• Login takes very long, annoying repaints once a minute when logged in: How to troubleshoot?

  - by user946850

  I am suffering from a strange problem with my Gnome Shell in Ubuntu 12.10. The login takes very long ( 30 sec), with a blank screen. In Google Chrome and Thunderbird (and perhaps in other applications), the main window freezes and is repainted in periodic intervals of less than one minute. The freeze takes several seconds, and it seems that font and appearance of, e.g., tabs and buttons briefly changes. Attempting to enable the second monitor show an error message related to XRANDR. Everything seems to have started three days ago, after I had to force-shutdown the machine while it was hibernating due to low power. (It was hibernating for quite a while and didn't want to stop.) Silly me. I have tried the following measures, with no avail: Checked all package file md5 hashes using debsums Reinstalled all packages using a variant of dpkg --get-selection \* | xargs apt-get install -reinstall Temporarily moved configuration directories such as .gconf, .config and .gnome2 to another location Created a new user account When I choose "Ubuntu" during login, the problems disappear. I am sort of frustrated that reinstalling all packages didn't fix the issue. How to troubleshoot this Gnome Shell (?) problem, short of reinstalling the system? (Or did anyone see this kind of behavior on their machine?)

• How do I partition my Hard drive to install Kubuntu?

  - by Xdflames

  I am a complete newbie to partitioning and I would like some guidance here. Can anyone explain what exactly I should be doing here? I am installing Kubuntu 12.04 on a currently Windows 7 laptop. My current Partitions say this: /dev/sda /dev/sda1 ntfs 104 MB 35 MB /dev/sda2 ntfs 319965 MB 87164 MB Basically, what I want is some guidance on what exactly to do here. All I want is a partition for my OS (Which will be Kubuntu 12.04) and a partition for all of my data. I also want to restart fresh with my hard drive, with only what I mentioned on here. I am installing Kubuntu from a flash drive (I set it up as a bootable device with Universal-USB-Installer-1.9.0.9), as I do not have any blank CDs/DVDs to burn to. What should I name my partitions? What should I set the type as? What size do they need to be? Edit: My hard drive is 320GB. Just looked it up in my BIOS. This computer will mainly be used for internet browsing and overall just messing around with the Linux OS.

• Java Dragging an object from one area to another [on hold]

  - by user50369

  Hello I have a game where you drag bits of food around the screen. I want to be able to click on an ingredient and drag it to another part of the screen where I release the mouse. I am new to java so I do not really know how to do this please help me Here is me code. This is the class with the mouse listeners in it: public void mousePressed(MouseEvent e) { if (e.getButton() == MouseEvent.BUTTON1) { Comp.ml = true; // placing if (manager.title == true) { if (title.r.contains(Comp.mx, Comp.my)) { title.overview = true; } else if (title.r1.contains(Comp.mx, Comp.my)) { title.options = true; } else if (title.r2.contains(Comp.mx, Comp.my)) { System.exit(0); } } if (manager.option == true) { optionsMouse(e); } mouseinventory(e); } else if (e.getButton() == MouseEvent.BUTTON3) { Comp.mr = true; } } private void mouseinventory(MouseEvent e) { if (e.getButton() == MouseEvent.BUTTON1) { } else if (e.getButton() == MouseEvent.BUTTON1) { } } @Override public void mouseReleased(MouseEvent e) { if (e.getButton() == MouseEvent.BUTTON1) { Comp.ml = false; } else if (e.getButton() == MouseEvent.BUTTON3) { Comp.mr = false; } } @Override public void mouseDragged(MouseEvent e) { for(int i = 0; i < overview.im.ing.toArray().length; i ++){ if(overview.im.ing.get(i).r.contains(Comp.mx,Comp.my)){ overview.im.ing.get(i).newx = Comp.mx; overview.im.ing.get(i).newy = Comp.my; overview.im.ing.get(i).dragged = true; }else{ overview.im.ing.get(i).dragged = false; } } } @Override public void mouseMoved(MouseEvent e) { Comp.mx = e.getX(); Comp.my = e.getY(); // System.out.println("" + Comp.my); } This is the class called ingredient public abstract class Ingrediant { public int x,y,id,lastx,lasty,newx,newy; public boolean removed = false,dragged = false; public int width; public int height; public Rectangle r = new Rectangle(x,y,width,height); public Ingrediant(){ r = new Rectangle(x,y,width,height); } public abstract void tick(); public abstract void render(Graphics g); } and this is a class which extends ingredient called hagleave public class HagLeave extends Ingrediant { private Image img; public HagLeave(int x, int y, int id) { this.x = x; this.y = y; this.newx = x; this.newy = y; this.id = id; width = 75; height = 75; r = new Rectangle(x,y,width,height); } public void tick() { r = new Rectangle(x,y,width,height); if(!dragged){ x = newx; y = newy; } } public void render(Graphics g) { ImageIcon i2 = new ImageIcon("res/ingrediants/hagleave.png"); img = i2.getImage(); g.drawImage(img, x, y, null); g.setColor(Color.red); g.drawRect(r.x, r.y, r.width, r.height); } } The arraylist is in a class called ingrediantManager: public class IngrediantsManager { public ArrayList<Ingrediant> ing = new ArrayList<Ingrediant>(); public IngrediantsManager(){ ing.add(new HagLeave(100,200,1)); ing.add(new PigHair(70,300,2)); ing.add(new GiantsToe(100,400,3)); } public void tick(){ for(int i = 0; i < ing.toArray().length; i ++){ ing.get(i).tick(); if(ing.get(i).removed){ ing.remove(i); i--; } } } public void render(Graphics g){ for(int i = 0; i < ing.toArray().length; i ++){ ing.get(i).render(g); } } }

• Problem with sprite direction and rotation

  - by user2236165

  I have a sprite called Tool that moves with a speed represented as a float and in a direction represented as a Vector2. When I click the mouse on the screen the sprite change its direction and starts to move towards the mouseclick. In addition to that I rotate the sprite so that it is facing in the direction it is heading. However, when I add a camera that is suppose to follow the sprite so that the sprite is always centered on the screen, the sprite won't move in the given direction and the rotation isn't accurate anymore. This only happens when I add the Camera.View in the spriteBatch.Begin(). I was hoping anyone could maybe shed a light on what I am missing in my code, that would be highly appreciated. Here is the camera class i use: public class Camera { private const float zoomUpperLimit = 1.5f; private const float zoomLowerLimit = 0.1f; private float _zoom; private Vector2 _pos; private int ViewportWidth, ViewportHeight; #region Properties public float Zoom { get { return _zoom; } set { _zoom = value; if (_zoom < zoomLowerLimit) _zoom = zoomLowerLimit; if (_zoom > zoomUpperLimit) _zoom = zoomUpperLimit; } } public Rectangle Viewport { get { int width = (int)((ViewportWidth / _zoom)); int height = (int)((ViewportHeight / _zoom)); return new Rectangle((int)(_pos.X - width / 2), (int)(_pos.Y - height / 2), width, height); } } public void Move(Vector2 amount) { _pos += amount; } public Vector2 Position { get { return _pos; } set { _pos = value; } } public Matrix View { get { return Matrix.CreateTranslation(new Vector3(-_pos.X, -_pos.Y, 0)) * Matrix.CreateScale(new Vector3(Zoom, Zoom, 1)) * Matrix.CreateTranslation(new Vector3(ViewportWidth * 0.5f, ViewportHeight * 0.5f, 0)); } } #endregion public Camera(Viewport viewport, float initialZoom) { _zoom = initialZoom; _pos = Vector2.Zero; ViewportWidth = viewport.Width; ViewportHeight = viewport.Height; } } And here is my Update and Draw-method: protected override void Update (GameTime gameTime) { float elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; TouchCollection touchCollection = TouchPanel.GetState (); foreach (TouchLocation tl in touchCollection) { if (tl.State == TouchLocationState.Pressed || tl.State == TouchLocationState.Moved) { //direction the tool shall move towards direction = touchCollection [0].Position - toolPos; if (direction != Vector2.Zero) { direction.Normalize (); } //change the direction the tool is moving and find the rotationangle the texture must rotate to point in given direction toolPos += (direction * speed * elapsed); RotationAngle = (float)Math.Atan2 (direction.Y, direction.X); } } if (direction != Vector2.Zero) { direction.Normalize (); } //move tool in given direction toolPos += (direction * speed * elapsed); //change cameracentre to the tools position Camera.Position = toolPos; base.Update (gameTime); } protected override void Draw (GameTime gameTime) { graphics.GraphicsDevice.Clear (Color.Blue); spriteBatch.Begin (SpriteSortMode.BackToFront, BlendState.AlphaBlend, null, null, null, null, Camera.View); spriteBatch.Draw (tool, new Vector2 (toolPos.X, toolPos.Y), null, Color.White, RotationAngle, originOfToolTexture, 1, SpriteEffects.None, 1); spriteBatch.End (); base.Draw (gameTime); }

• Booting Ubuntu 12.04 from external eSATA disk

  - by Lord of Scripts

  This is my system topology: Disk #1 (SATA Internal) C: D: (Windows 7 Ultimate) Disk #2 (SATA Internal) E: (Windows Backup) Disk #3 (eSATA External) H: I: (Other windows data) /dev/sdc3 Linux Swap /dev/sdc4 Extended partition /dev/sdc5 Linux / So, I originally had there Ubuntu 8.1 from years ago but never got to use it. Now I used the Ubuntu 12.04 Live CD to install on that same location (That live CD takes a century to boot on a 6GB Intel i7 system...). The installation went fine, I selected it to install on /dev/sdc5 but it never asked me for any boot stuff, where I wanted to install Grub or whatever it is that it uses nowaways (I come from the LILO days when it always worked :-) So, yet again I can't access my new Linux installation. I have to wait a century to boot the "Live" CD and it allows me to see my new installation but I can't do anything with it. I tried the approach of this blog post. Copied the linux.bin of /dev/sdc5 into C: and used the BCDEdit steps to declare the new OS. So when I boot I see the Windows Boot menu and select Linux and after than I only get a black screen with a blinking cursor on the upper left. I can boot into Windows though. So, perhaps it didn't install the boot code on /dev/sdc5? I used this setup years ago booting from Windows with a BIN file: dd if=/dev/sdc5 of=/mnt/share/C/linux.bin bs=512 count=1 I am very reluctant to run GRUB because years ago I did and it wiped out my Windows boot sector and took quite some effort to recover it and be able to boot Windows again. I have been trying to install GRUB on a blank USB stick but I can't find anything clear enough. My system does NOT have a floppy. So can someone give me some ideas about how to get control of my Ubuntu 12.04 installation?

• OpenGL Fast-Object Instancing Error

  - by HJ Media Studios

  I have some code that loops through a set of objects and renders instances of those objects. The list of objects that needs to be rendered is stored as a std::map, where an object of class MeshResource contains the vertices and indices with the actual data, and an object of classMeshRenderer defines the point in space the mesh is to be rendered at. My rendering code is as follows: glDisable(GL_BLEND); glEnable(GL_CULL_FACE); glDepthMask(GL_TRUE); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glEnable(GL_DEPTH_TEST); for (std::map<MeshResource*, std::vector<MeshRenderer*> >::iterator it = renderables.begin(); it != renderables.end(); it++) { it->first->setupBeforeRendering(); cout << "<"; for (unsigned long i =0; i < it->second.size(); i++) { //Pass in an identity matrix to the vertex shader- used here only for debugging purposes; the real code correctly inputs any matrix. uniformizeModelMatrix(Matrix4::IDENTITY); /** * StartHere fix rendering problem. * Ruled out: * Vertex buffers correctly. * Index buffers correctly. * Matrices correct? */ it->first->render(); } it->first->cleanupAfterRendering(); } geometryPassShader->disable(); glDepthMask(GL_FALSE); glDisable(GL_CULL_FACE); glDisable(GL_DEPTH_TEST); The function in MeshResource that handles setting up the uniforms is as follows: void MeshResource::setupBeforeRendering() { glEnableVertexAttribArray(0); glEnableVertexAttribArray(1); glEnableVertexAttribArray(2); glEnableVertexAttribArray(3); glEnableVertexAttribArray(4); glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, iboID); glBindBuffer(GL_ARRAY_BUFFER, vboID); glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, sizeof(Vertex), 0); // Vertex position glVertexAttribPointer(1, 3, GL_FLOAT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 12); // Vertex normal glVertexAttribPointer(2, 2, GL_FLOAT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 24); // UV layer 0 glVertexAttribPointer(3, 3, GL_FLOAT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 32); // Vertex color glVertexAttribPointer(4, 1, GL_UNSIGNED_SHORT, GL_FALSE, sizeof(Vertex), (const GLvoid*) 44); //Material index } The code that renders the object is this: void MeshResource::render() { glDrawElements(GL_TRIANGLES, geometry->numIndices, GL_UNSIGNED_SHORT, 0); } And the code that cleans up is this: void MeshResource::cleanupAfterRendering() { glDisableVertexAttribArray(0); glDisableVertexAttribArray(1); glDisableVertexAttribArray(2); glDisableVertexAttribArray(3); glDisableVertexAttribArray(4); } The end result of this is that I get a black screen, although the end of my rendering pipeline after the rendering code (essentially just drawing axes and lines on the screen) works properly, so I'm fairly sure it's not an issue with the passing of uniforms. If, however, I change the code slightly so that the rendering code calls the setup immediately before rendering, like so: void MeshResource::render() { setupBeforeRendering(); glDrawElements(GL_TRIANGLES, geometry->numIndices, GL_UNSIGNED_SHORT, 0); } The program works as desired. I don't want to have to do this, though, as my aim is to set up vertex, material, etc. data once per object type and then render each instance updating only the transformation information. The uniformizeModelMatrix works as follows: void RenderManager::uniformizeModelMatrix(Matrix4 matrix) { glBindBuffer(GL_UNIFORM_BUFFER, globalMatrixUBOID); glBufferSubData(GL_UNIFORM_BUFFER, 0, sizeof(Matrix4), matrix.ptr()); glBindBuffer(GL_UNIFORM_BUFFER, 0); }

• XNA WP7 Texture memory and ContentManager

  - by jlongstreet

  I'm trying to get my WP7 XNA game's memory under control and under the 90MB limit for submission. One target I identified was UI textures, especially fullscreen ones, that would never get unloaded. So I moved UI texture loads to their own ContentManager so I can unload them. However, this doesn't seem to affect the value of Microsoft.Phone.Info.DeviceExtendedProperties.GetValue("ApplicationCurrentMemoryUsage"), so it doesn't look like the memory is actually being released. Example: splash screens. In Game.LoadContent(): Application.Instance.SetContentManager("UI"); // set the current content manager for (int i = 0; i < mSplashTextures.Length; ++i) { // load the splash textures mSplashTextures[i] = Application.Instance.Content.Load<Texture2D>(msSplashTextureNames[i]); } // set the content manager back to the global one Application.Instance.SetContentManager("Global"); When the initial load is done and the title screen starts, I do: Application.Instance.GetContentManager("UI").Unload(); The three textures take about 6.5 MB of memory. Before unloading the UI ContentManager, I see that ApplicationCurrentMemoryUsage is at 34.29 MB. After unloading the ContentManager (and doing a full GC.Collect()), it's still at 34.29 MB. But after that, I load another fullscreen texture (for the title screen background) and memory usage still doesn't change. Could it be keeping the memory for these textures allocated and reusing it? edit: very simple test: protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. spriteBatch = new SpriteBatch(GraphicsDevice); PrintMemUsage("Before texture load: "); // TODO: use this.Content to load your game content here red = this.Content.Load<Texture2D>("Untitled"); PrintMemUsage("After texture load: "); } private void PrintMemUsage(string tag) { Debug.WriteLine(tag + Microsoft.Phone.Info.DeviceExtendedProperties.GetValue("ApplicationCurrentMemoryUsage")); } protected override void Update(GameTime gameTime) { // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); // TODO: Add your update logic here if (count++ == 100) { GC.Collect(); GC.WaitForPendingFinalizers(); PrintMemUsage("Before CM unload: "); this.Content.Dispose(); GC.Collect(); GC.WaitForPendingFinalizers(); PrintMemUsage("After CM unload: "); red = null; spriteBatch.Dispose(); GC.Collect(); GC.WaitForPendingFinalizers(); PrintMemUsage("After SpriteBatch Dispose(): "); } base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); // TODO: Add your drawing code here if (red != null) { spriteBatch.Begin(); spriteBatch.Draw(red, new Vector2(0,0), Color.White); spriteBatch.End(); } base.Draw(gameTime); } This prints something like (it changes every time): Before texture load: 7532544 After texture load: 10727424 Before CM unload: 9875456 After CM unload: 9953280 After SpriteBatch Dispose(): 9953280

• Tracking Protection List in IE9

  - by Emanuele Bartolesi

  To protect the privacy when I surf over the internet, I use AdBlockPlus add-in for Firefox. But when I use Internet Explorer 9, this add-in don’t work. Internet Explorer 9 (and I hope Internet Explorer 10) has built in feature to add a TPL. There is a javascript function to call named msAddTrackingProtectionList. This function has two parameter: the first one is the link of TPL and the second one is the Title of TPL. To do this is very easy. Add this simple javascript function on your website or in a blank html page. <a href="javascript:window.external.msAddTrackingProtectionList('http://easylist-msie.adblockplus.org/easyprivacy.tpl', 'EasyList Privacy')">EasyPrivacy TPL</a> The effect is below: EasyPrivacy TPL After click appears a confirmation prompt. For security reason this javascript function can only be called from a user interaction: buttons, links, forms. For more information about msAddTrackingProtectionList function  go to Msdn Library. For more information about EasyList go to Easy List TPL.

• Location-Based redirection and duplication in sub-directories affecting SEO

  - by Joshua

  I currently own the website www.xyz.com. The website has a sub-directory for each of the 3 target countries: .../en-US/ (United States), .../es-MX/ (Mexico), and .../es-DO/ (Dominican Republic). I have two main questions about this setup: Currently, the main domain/root (xyz.com) contains a blank index.php file, but I would like for a user to be redirected to one of the sub-directories based on their regional location. What is the best way to accomplish this? I have looked at using browser language-based redirection, but how would I know whether to direct a user to the MX or DO site if the browser language is set to spanish? Is there a way to detect a user's geographic location? Also, the 3 websites are practically identical except they all have 3 unique color schemes and the US site is in english while the MX and DO sites are in spanish. My problem is that I believe GoogleBot is penalizing/banning my site because the spanish text on the MX and DO pages are nearly identical and are thus marked as duplicates/spam. Is there a way to avoid this?

• Twitter "Authentication Error" Turpial & Choqok (latest versions)

  - by PineMarten

  I use Turpial a lot, but Turpial isn't connecting at all. I can still connect to Twitter thru the OS app (no issues signing in through Online Accounts) and of course I can still sign in using the browser, but Turpial gives me an "Authentication Error" and Choqok fails to do anything. I've tried changing my password, revoking the Turpial and Ubuntu apps in Twitter and re-enabling them, but then it gives me an "Invalid Credentials" message. I've even removed and installed Turpial multiple times, still nothing. I can't find any information or resources for this type of error from Turpial online. I think it may be something recent after finding this message elsewhere: (article related to "Birdie") It looks promising i'm currently using it atm, since all the other twitter clients no longer work due to the API 1.0 shutdown (posted today) I've never used Choqok before today, so I don't even know if I've set it up properly. It's failing to retrieve or send Tweets it just blank screens, but at least it signs in. I've figured that this isn't an issue with Ubuntu, or Turpial or Choqok, or the router (already replaced it today), so I don't really know what I'm dealing with here. I hope it's not another API issue, Facebook did something similar just a few weeks ago

• ubuntu 12.04 installer does not recognize drive partitions

  - by endless forms

  I recently purchased a new HP Pavilion HPE desktop running Windows 7. I am trying to install a dual-boot system with 12.04. However, when I run the LiveCD I only get as far as the "Install" window where you can select the partitions for your drives. On the bottom where it says "device for boot loader installation" I have "/dev/sda" and cannot select any other devices. All the options to change the drives are greyed out, most likely because there are no drives in the window. I partitioned my largest drive using the tools within Windows, then booted into the CD, but nothing shows up. I then used Gparted to change the new space from unallocated to an /ext2, and still nothing shows up. The installer does not recognize anything, but when I go into an Ubuntu session and use the disk utility manager I can see the partitions I made. Anything I do has to be done outside of the installer. I have no files on this new computer, so this is the perfect time to install a parallel OS. I would like avoid completely reinstalling Windows, however. I've been over the forums many times, but all the answers I've found have not worked for me. I also tried flagging the new, empty partition as boot, but that screwed Windows up. Also, the WUBI installer hits the same point and quits. I know that the disk itself is fine because I just made another dual boot system on a Gateway PC. This makes me think something within this computer is preventing the installer from "seeing" the drives. Any help would be much appreciated! Edit in response: The main part of the partitioning window shows no partitions, everything is blank. There is no way to add partitions, and all the buttons are useless. I've tried defragging my drive multiple times, and I also used the same disk to dual-boot another PC with no problems, so it's not the disk, it's definitely the computer.

• 13.04 Temp Save, rt3290, Kernel downgrade

  - by user170534

  It's kind of a multiplying but I didn't wanted to open more than one topics. I'd have a fresh install of Ubuntu with tlp configured and using acpi_call to keep 7670M turned off. I was a short time arch user and with openbox and firefox it was about 60 to 70 degrees; wanted to turn to a stable release just for this reason. acpitz-virtual-0 Adapter: Virtual device temp1: +50.0°C radeon-pci-0100 Adapter: PCI adapter temp1: -128.0°C coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +56.0°C (high = +87.0°C, crit = +105.0°C) Core 0: +54.0°C (high = +87.0°C, crit = +105.0°C) Core 1: +55.0°C (high = +87.0°C, crit = +105.0°C) The temperature is not seriously high yet can be lower. Another issue is my wifi card, rt3290: The rt2800pci module is fine and all that but the download performance is pretty bad alongside of annoying signal range and the prop. driver gives a conf error about some specific rt2860 code and integrales in pci_dev file. If I blank off the error making variables, module loads but the driver is unused. Since the driver is old, I was thinking of downgrading the kernel of raring to 3.7 or may be 3.6. Should &-or can I?

• JQueryMobile - Problems with dialog boxes [closed]

  - by Richard van Hees

  I'm programming in JQueryMobile, but I can't seem to get some things as I want. First it's good to tell I am mostly programming in a multi-page template. I have a login function in the web based app. The idea is that the user sees he's not logged in and the user can click on the button to log in. A dialog box pops up, in which the user can enter his credentials. This dialog box is in front of the previous page, in my case just index.php. The page for profile is at profile.php#profile. In this case the url for the dialog box is index.php#profile&ui-state=dialog. Don't ask me why, that's how JQueryMobile works, I guess. Anyway, after the user clicks on 'Login' in the pop-up, I want a new dialog to pop-up in which it says you are logged in and I want the content of the page behind it (index.php#profile) to refresh. Of course I want this all to move very smooth and no refreshing of the whole page, to prevent loading time and thus a blank screen for a second. In short: User not logged in Clicks on login Dialog pops up with form Clicks login New dialog pops up with 'success' (or whatever) in the same style as the previous dialog Clicks ok Page behind the dialogues has been refreshed without user noticing Also another thing that doesn't really work out for me: I can't seem to get a dialog to pop up, triggered by an action in another dialog. It just appears as a normal page.

• Cannot establish maximum resolution on ASUS PB278Q

  - by dentuzhik

  I've recently bought brand new ASUS PB278Q monitor. When trying to connect to my laptop, everything works great, except that I can't get the native resolution of my monitor (2560x1440) working. The automatic is 1920x1080. My graphic card is Nvidia GeForce 320m. Here's output from lspci for it: ~$ lspci | grep VGA 02:00.0 VGA compatible controller: NVIDIA Corporation GT216M [GeForce GT 320M] (rev a2) and also xrandr: ~$ xrandr Screen 0: minimum 8 x 8, current 3286 x 1437, maximum 8192 x 8192 VGA-0 disconnected (normal left inverted right x axis y axis) LVDS-0 connected primary 1366x768+0+669 (normal left inverted right x axis y axis) 344mm x 193mm 1366x768 60.0*+ HDMI-0 connected 1920x1080+1366+0 (normal left inverted right x axis y axis) 600mm x 340mm 1920x1080 60.0*+ 59.9 50.0 30.0 25.0 24.0 60.0 50.0 1680x1050 60.0 1440x900 59.9 1280x1024 75.0 60.0 1280x960 60.0 1280x800 59.8 1280x720 60.0 59.9 50.0 1152x864 75.0 1024x768 75.0 70.1 60.0 800x600 75.0 72.2 60.3 56.2 720x576 50.0 720x480 59.9 640x480 75.0 59.9 59.9 480x576 50.0 480x480 59.9 I have proprietary drivers installed on my machine, here's the info about the monitor from nvidia-settings (Actually I don't have enough reputation to post images, so here's the text): Chip Location: Internal Signal: TDMS Connection link: Single Native resolution: 2560x1440 Refresh rate: 60.00 Hz The monitor is connected to laptop via HDMI cable, and honestly I have no idea what version it is, and what version is my HDMI output of my graphics card. I tried to find how I can figure it out on the web, but had no luck. Also my video card has only VGA and HDMI outs so I can't test neither DVI-D cable nor DisplayPort. So apparently, there's some problem over there. At least I want to know exactly what's going on. I've tried to see if it a linux-specific problem, but windows also gave me the same resolution by default. What I've already tried: Connect through VGA (stupid one, of course it gave me 1920x1080). Checked two HDMI cables (not sure if they're the same or not, as mentioned above). Played around with xrandr and adding custom modes. Didn't help. Surfed for the info a lot on the web, but couldn't get appropriate results. Actually xrandr gives me the following: ~$ cvt 2560 1440 60 # 2560x1440 59.96 Hz (CVT 3.69M9) hsync: 89.52 kHz; pclk: 312.25 MHz Modeline "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync ~$ xrandr --newmode "2560x1440_60.00" 312.25 2560 2752 3024 3488 1440 1443 1448 1493 -hsync +vsync ~$ xrandr Screen 0: minimum 8 x 8, current 3286 x 1437, maximum 8192 x 8192 VGA-0 disconnected (normal left inverted right x axis y axis) LVDS-0 connected 1366x768+0+669 (normal left inverted right x axis y axis) 344mm x 193mm 1366x768 60.0*+ HDMI-0 connected primary 1920x1080+1366+0 (normal left inverted right x axis y axis) 600mm x 340mm 1920x1080 60.0*+ 59.9 50.0 30.0 25.0 24.0 60.0 50.0 1680x1050 60.0 1440x900 59.9 1280x1024 75.0 60.0 1280x960 60.0 1280x800 59.8 1280x720 60.0 59.9 50.0 1152x864 75.0 1024x768 75.0 70.1 60.0 800x600 75.0 72.2 60.3 56.2 720x576 50.0 720x480 59.9 640x480 75.0 59.9 59.9 480x576 50.0 480x480 59.9 2560x1440_60.00 (0x34f) 312.2MHz h: width 2560 start 2752 end 3024 total 3488 skew 0 clock 89.5KHz v: height 1440 start 1443 end 1448 total 1493 clock 60.0Hz ~$ xrandr --addmode HDMI-0 2560x1440_60.00 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 18 (RRAddOutputMode) Serial number of failed request: 29 Current serial number in output stream: 30 What I intend to do next: Try another HDMI cable? Try HDMI to DVI-D cable? Try HDMI to DisplayPort cable? Another type of adapters? VGA to DVI-D? Buy another laptop with another graphic card. Damn. My ideas pretty much end here. Any ideas? Any explanations why it isn't working are appreciated.

• Package Manager cannot access repositories but internet is working

  - by kazman

  I am currently at a conference in another country and my package manager cannot access repositories. My internet is working fine and I can ping the repositories or go to them in a browser, but package manager fails to access them. If I sudo apt-get update it throws Something wicked happened resolving 'wwwproxy:3128' (-5 - No address associated with hostname) (or Ign's). This proxy corresponds to my proxy at my office back at home, but I have disabled proxy in the package manager. Scanning for best repository doesn't work either, it doesn't manage to connect to any. I have searched for this online and have checked things about my apt.conf file. My apt.conf contains: Acquire::http::proxy "http://wwwproxy:3128/"; Acquire::https::proxy "https://wwwproxy:3128/"; Acquire::ftp::proxy "ftp://wwwproxy:3128/"; Acquire::socks::proxy "socks://wwwproxy:3128/"; If I remove apt.conf (or replace with blank), it makes no difference. I don't see that it should since I am connecting directly (and have set it so in my network options in Package manager network settings) I have also tried some things with resolv.conf (changing name address to primary and secondary dns) to no avail. (im not sure if this would help, following other advice) I am running 12.04. (I wrote this very quickly and wrote down everything I have tried to possibly shorten the troubleshooting process, have very limited time between lectures and need this sorted asap, my apologies)

• Storing a pass-by-reference parameter as a pointer - Bad practice?

  - by Karl Nicoll

  I recently came across the following pattern in an API I've been forced to use: class SomeObject { public: // Constructor. SomeObject(bool copy = false); // Set a value. void SetValue(const ComplexType &value); private: bool m_copy; ComplexType *m_pComplexType; ComplexType m_complexType; }; // ------------------------------------------------------------ SomeObject::SomeObject(bool copy) : m_copy(copy) { } // ------------------------------------------------------------ void SomeObject::SetValue(const ComplexType &value) { if (m_copy) m_complexType.assign(value); else m_pComplexType = const_cast<ComplexType *>(&value); } The background behind this pattern is that it is used to hold data prior to it being encoded and sent to a TCP socket. The copy weirdness is designed to make the class SomeObject efficient by only holding a pointer to the object until it needs to be encoded, but also provide the option to copy values if the lifetime of the SomeObject exceeds the lifetime of a ComplexType. However, consider the following: SomeObject SomeFunction() { ComplexType complexTypeInstance(1); // Create an instance of ComplexType. SomeObject encodeHelper; encodeHelper.SetValue(complexTypeInstance); // Okay. return encodeHelper; // Uh oh! complexTypeInstance has been destroyed, and // now encoding will venture into the realm of undefined // behaviour! } I tripped over this because I used the default constructor, and this resulted in messages being encoded as blank (through a fluke of undefined behaviour). It took an absolute age to pinpoint the cause! Anyway, is this a standard pattern for something like this? Are there any advantages to doing it this way vs overloading the SetValue method to accept a pointer that I'm missing? Thanks!

• No boot option after installing Ubuntu 12.04 LTS on Acer Aspire 4736z with Live CD

  - by utamaku

  I am facing a problem. After installing Ubuntu 12.04 LTS using Live CD, at the reboot there is no boot option to choose the OS. I directly get logged into my Windows 7. Before that i was having an issue with the 'nomodeset' if not mistaken .After ticking [x] on the nomodeset, i can install my Ubuntu, but got stucked again at choosing the partition option. So i did 2 partitions for Ubuntu, 1 partition as ext3 for / and the other 1 for swap. Which enabled to proceed until the finished installation dialogue, and after that system wants to reboot .It takes some time and gets stuck at the screen doing nothing, doesn't reboot at all. I did forced shutdown then rebooted again which directly logs me in windows 7 without boot option. In win7 the partitions for Ubuntu is gone. I tried the boot-repair thing and it doesn't help .It just shows up the _ Blank Cursor (terminal thing i guess). I typed boot repair but still the same result. I am using Acer Aspire 4736z. Please somebody help me with this issue.

• What is meant by "no password set" for root account (and otthers)?

  - by MMA

  Several years back, we were more accustomed to changing to the root account using the su command. First, we switched to the root account, and then executed those root commands. Now we are more accustomed to using the sudo command. But we know that the root account is there. We can readily find the home directory of user root. $ ls -ld /root/ drwx------ 18 root root 4096 Oct 22 17:21 /root/ Now my point is, it is stated that "the root password in Ubuntu is left unset". Please see the answers to this question. Most of the answers have something to this effect in the first paragraph. One or two answers further state that "the account is left disabled". Now my (primary) questions are, What is meant by an unset password? Is it blank? Is it null? Or something else more cryptic? How does the account becomes enabled once I set password for it? (sudo password root) In order get a better understanding, I checked the /etc/shadow file. Since I have already set a password for the root account, I can no longer see what is there (encrypted password). So, I created another account and left it disabled. The corresponding entry in the /etc/shadow file is, testpassword:!:16020:0:99999:7::: Now perhaps my above queries need to be changed to, what does an ! in password field mean? Other encrypted passwords are those very long cryptic strings. How come this encrypted form is only one character long? And does an account become disabled if I put an ! in the (encrypted) password field?

• how to recover lost partitions data

  - by TheJoester

  I have a 2TB SATA drive that was being used as file storage on my UBUNTU computer. I was re-imaging my windows box so I used that drive to back up some files to it. I did this by taking the drive from my windows PC and putting it in my UBUNTU PC, mounted it and copied the files over. After the windows refresh I thought it would be easier to take the 2 TB drive and dock it in the external dock my Windows case has built in. Anyway it would recognize in BIOS but windows would not see it (because it was EXT3 or EXT4) so when I went into the disk manager it advised me the drive needed to be initialized. Me not thinking I initialized it as a GUID Partition table. Now it sees it as a blank drive, even in UBUNTU. I have done nothing else to write or change the drive. I was wondering if there is a qay to repair the old partitioning and get access to my files back? many thanks! EDIT: I followed the instructions in the link @kniwor sent me. I used the command sudo gpart -W /dev/sda /dev/sda and here was the result: Guessed primary partition table: Primary partition(1) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) size: 0mb #s(1) s(2861671176-2861671176) chs: (1023/254/63)-(1023/254/63)d (178130/202/1)-(178130/202/1)r Primary partition(2) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) size: 0mb #s(1) s(3484550160-3484550160) chs: (1023/254/63)-(1023/254/63)d (216903/55/1)-(216903/55/1)r Primary partition(3) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Primary partition(4) type: 000(0x00)(unused) size: 0mb #s(0) s(0-0) chs: (0/0/0)-(0/0/0)d (0/0/0)-(0/0/0)r Not sure it found what I wanted. suggestions?

• Trouble installing from disk

  - by SuperNatural

  I'm writing this in desperation, Windows is slowly killing me and i need to change my home pc os to Ubuntu 11.04 as soon as possible. I created a USB flash drive to install ubuntu, twice, and both times they failed to begin install on restart of my pc. i read on another forum that you might have to change some boot sequence in BIOS but when pressing F2 to enter it didnt work. After a lot of cursing, I made myself an UBUNTU install cd and booted. To my excitement, it now displayed... try ubuntu and install ubuntu. i clicked install ubuntu which lead me to the preparing to install ubuntu display, i checked download updates while installing and clicked forward. The very next display is ' allocate drive space ' i assume there are meant to be options of drives provided but mine is just a blank box and underneath all the options to create a new partition table, add, change, delete and revert are all greyed out. There is a drop down menu labelled 'device for boot loader installlation' but the only option is /dev/sda. when i click install, a no root file system error comes up telling me to please correct from the partitioning menu. I am extremely frustrated. please!! can anyone help me...

• Installed geany has no options

  - by arundex

  I'm new to geany IDE. I installed geany from ubuntu software centre, and the window has no options other than opening a new file. I can't file any preference, tools option too for configuring. I heard it is a full fledged IDE. Also, from the screenshots available from the software center, it seems my Geany installation is missing almost everything. I'm not able to post the screenshots, but my interface just has 3 buttons. create a new file, open an existing file and a quit button. Everything else is inactive. I accidentally closed the sidepane, and I can't find any options to bring back that too. EDIT What am I missing in my Geany installation? PS: I tried installing from source from geany website. But, it posted some error saying GTK files not found. But, I removed geany from software centre and reinstalled several times. It installed Geany without problems, but with afore mentioned problems, that is I have nothing in my interface. Also, even after reinstalling, somehow Geany remembers to hide the sidepane by default, which I'm not able to see at all. I also added Geany ppa repository manually for latest fixes, but still when I reinstall from software centre I get a plain blank Geany interface. Thanks.

• Windows Phone 7 development: reading RSS feeds

  - by DigiMortal

  One limitation on Windows Phone 7 is related to System.Net namespace classes. There is no convenient way to read data from web. There is no WebClient class. There is no GetResponse() method – we have to do it all asynchronously because compact framework has limited set of classes we can use in our applications to communicate with internet. In this posting I will show you how to read RSS-feeds on Windows Phone 7. NB! This is my draft code and it may contain some design flaws and some questionable solutions. This code is intended to use as test-drive for Windows Phone 7 CTP developer tools and I don’t suppose you are going to use this code in production environment. Current state of my RSS-reader Currently my RSS-reader for Windows Phone 7 is very simple, primitive and uses almost all defaults that come out-of-box with Windows Phone 7 CTP developer tools. My first goal before going on with nicer user interface design was making RSS-reading work because instead of convenient classes from .NET Framework we have to use very limited classes from .NET Framework CE. This is why I took the reading of RSS-feeds as my first task. There are currently more things to solve regarding user-interface. As I am pretty new to all this Silverlight stuff I am not very sure if I can modify default controls easily or should I write my own controls that have better look and that work faster. The image on right shows you how my RSS-reader looks like right now. Upper side of screen is filled with list that shows headlines from this blog. The bottom part of screen is used to show description of selected posting. You can click on the image to see it in original size. In my next posting I will show you some improvements of my RSS-reader user interface that make it look nicer. But currently it is nice enough to make sure that RSS-feeds are read correctly. FeedItem class As this is most straight-forward part of the following code I will show you RSS-feed items class first. I think we have to stop on it because it is simple one. public class FeedItem {     public string Title { get; set; }     public string Description { get; set; }     public DateTime PublishDate { get; set; }     public List<string> Categories { get; set; }     public string Link { get; set; }       public FeedItem()     {         Categories = new List<string>();     } } RssClient RssClient takes feed URL and when asked it loads all items from feed and gives them back to caller through ItemsReceived event. Why it works this way? Because we can make responses only using asynchronous methods. I will show you in next section how to use this class. Although the code here is not very good but it works like expected. I will refactor this code later because it needs some more efforts and investigating. But let’s hope I find excellent solution. :) public class RssClient {     private readonly string _rssUrl;       public delegate void ItemsReceivedDelegate(RssClient client, IList<FeedItem> items);     public event ItemsReceivedDelegate ItemsReceived;       public RssClient(string rssUrl)     {         _rssUrl = rssUrl;     }       public void LoadItems()     {         var request = (HttpWebRequest)WebRequest.Create(_rssUrl);         var result = (IAsyncResult)request.BeginGetResponse(ResponseCallback, request);     }       void ResponseCallback(IAsyncResult result)     {         var request = (HttpWebRequest)result.AsyncState;         var response = request.EndGetResponse(result);           var stream = response.GetResponseStream();         var reader = XmlReader.Create(stream);         var items = new List<FeedItem>(50);           FeedItem item = null;         var pointerMoved = false;           while (!reader.EOF)         {             if (pointerMoved)             {                 pointerMoved = false;             }             else             {                 if (!reader.Read())                     break;             }               var nodeName = reader.Name;             var nodeType = reader.NodeType;               if (nodeName == "item")             {                 if (nodeType == XmlNodeType.Element)                     item = new FeedItem();                 else if (nodeType == XmlNodeType.EndElement)                     if (item != null)                     {                         items.Add(item);                         item = null;                     }                   continue;             }               if (nodeType != XmlNodeType.Element)                 continue;               if (item == null)                 continue;               reader.MoveToContent();             var nodeValue = reader.ReadElementContentAsString();             // we just moved internal pointer             pointerMoved = true;               if (nodeName == "title")                 item.Title = nodeValue;             else if (nodeName == "description")                 item.Description =  Regex.Replace(nodeValue,@"<(.|\n)*?>",string.Empty);             else if (nodeName == "feedburner:origLink")                 item.Link = nodeValue;             else if (nodeName == "pubDate")             {                 if (!string.IsNullOrEmpty(nodeValue))                     item.PublishDate = DateTime.Parse(nodeValue);             }             else if (nodeName == "category")                 item.Categories.Add(nodeValue);         }           if (ItemsReceived != null)             ItemsReceived(this, items);     } } This method is pretty long but it works. Now let’s try to use it in Windows Phone 7 application. Using RssClient And this is the fragment of code behing the main page of my application start screen. You can see how RssClient is initialized and how items are bound to list that shows them. public MainPage() {     InitializeComponent();       SupportedOrientations = SupportedPageOrientation.Portrait | SupportedPageOrientation.Landscape;     listBox1.Width = Width;       var rssClient = new RssClient("http://feedproxy.google.com/gunnarpeipman");     rssClient.ItemsReceived += new RssClient.ItemsReceivedDelegate(rssClient_ItemsReceived);     rssClient.LoadItems(); }   void rssClient_ItemsReceived(RssClient client, IList<FeedItem> items) {     Dispatcher.BeginInvoke(delegate()     {         listBox1.ItemsSource = items;     });            } Conclusion As you can see it was not very hard task to read RSS-feed and populate list with feed entries. Although we are not able to use more powerful classes that are part of full version on .NET Framework we can still live with limited set of classes that .NET Framework CE provides.
