  • No such device = Grub Rescue 13.10

    - by LittleBeard
    Noob here. I just installed 13.10 yesterday And it booted up for me several times and all was well. Then this morning when I went to boot I received a "No such device" error and a "grub rescue" command line prompt. I tried running the live disc and re-installing Ubuntu 13.10 However that was a fail. The same messages kept occurring. Then I tried to boot up in Windows 7. Also a fail. I then attempted to run a Windows 7 restore disc. You guessed it - Fail. This sucks. What do I do?

  • Ubuntu not booting after upgrade to 12.04 from 11.10

    - by ddd
    I upgraded to 12.04 from 11.10 today. After the upgrade, I did the usual reboot of the system and then Ubuntu hangs on Checking battery state..[OK]. I can login to terminal with Ctrl-Alt-F5 and I did startx but it hangs after displaying white images of the desktop icons..there is no menu or any top bar at all. I guess this problem has something to do with Xserver, but I cannot find xorg.conf on my system. How can I get around this problem? Also is there a way I can make a backup of my files through the command line, because the GUI is not showing up at all?

  • What does ^+Z do to a process

    - by Kifsif
    In command line I wrote: michael@ubuntu:~$ firefox Firefox launched. Command prompt ($) disappeared. Then I pressed ^+z. The result was: [1]+ Stopped firefox Well, Firefox really stopped. It did not react anyhow. So, I could not close it by pressing the cross of the window. By the way, the menu items 'Tools', and 'Help' somehow showed some signs of life. They showed drop-down lists, but nothing more (no reaction to inner menu items). Well, I could not end Firefox through System Monitor. Could you comment on this case: what happened after pressing ^+z?

  • Ubuntu 14.04 upgrade succeeded partially - I would like to use a different mirror; how can I do that?

    - by user290648
    When I wanted to upgrade from Ubuntu 13.10 to 14.04 the update manager told me that there was an unresolvable problem with calculating the upgrade. In order to see more details I performed the following on the command line: apt-get update apt-get upgrade apt-get dist-upgrade apt-get install update-manager-core do-release-upgrade Now do-release-upgrade tells me that no newer version is available but the "about" box in the main menu tells me I am still on 13.10. I think the latter is right, as for instance in the "system settings" there is no way to select local menus, which is present in 14.04 (I tried with a DVD, and there it is). Maybe the problem is related to the fact that "apt-get update" cannot get two resources called "saucy/InRelease" and "saucy/main/binary-i386/Packages" from the mirror (mirror.informatik.uni-mannheim.de; 404 not found). I would like to use a different mirror; how can I do that? Any help appreciated, thanks in advance.

  • 12.04 install now just blank screen

    - by bull
    I have attempted to install a new copy of 12.04 using usb stick instead of using download manager. Everything went fine while using usb stick until I restarted after installation was complete. Then, I got the screen with cursor and 4 lines of script with the first line saying "could not write to bytes: broken pipes". I have used several versions of Ubuntu from 6.04, but this one seems broken. I have tried nouveau.blacklist and many other suggestions to no luck. I am using hp pavilion m7790y dual core processor system, with nvidia 7600gt video card, 4gb ram and two hard drives with Vista on one and fresh install of Ubuntu 12.04 on other. I'm still looking for help to solve this problem. Thanks in advance.

  • Is there a batch processing framework that could be used for C++ applications?

    - by Benjamin
    In my team we develop several command-line C++ applications that work together; they're currently run by hand in separate windows, and after a while managing windows gets really confusing. I'm looking for a better way to manage the processing of these applications; ideally it would have a GUI with the ability to do the following: start applications in a specified order display application status close particular applications Is there anything available that does this type of thing or would we need to develop our own? Is there a better way than this?

  • Generate Unique Abstract Backgrounds with Ablaze

    - by Jason Fitzpatrick
    If you want custom and unique backgrounds without having to code your own image-generating engine, Ablaze makes it simple (and fun) to create abstract images. You can customize a wide array of options in Ablaze including the base shape (ring, horizontal line, or random), number of particles, distance each particle travels, and the speed (if you increase the speed range you get more distinct lines and if you decrease it you get smoother smokier shapes). You can also seed the design with a color palette pulled from any image you provide (the sample above was seeded with a Wonder Woman comic panel). Tweak and reset the pattern generation as much as you want; when you create an abstract image worthy of your desktop just click the save button to grab a copy of it in PNG format.

  • Overview of the agile process that I can apply to a startup

    - by Pete2k
    I need to provide a quote to an external client for some software. I'm looking to use agile just for initial requirements building (which I'm experienced in from a developer perspective) but I need to do everything this is just a one man job. The client are having a hard time working out what there requirements are and the value I can add will be to sit down with them and work out what they want using user stories etc, I basically need to be a BA for a little bit. I am looking for good overview of the procedures to go through in the agile process for building requirements, and the continuing process a bit for further down the line. For example the initial inception through to elaboration of epics and building user stories (or not) just need to read a bit about it before the meeting so I know the best way to proceed if I spend a day with them. Having additional resources to provide to the client so that we are all on the same page would be useful too.

  • GUI is not displayed anymore

    - by mdobrinin
    I am running 12.04 LTS on a VM. I encountered a problem with the screen being black and the familiar orange background showing for a fraction of a second when clicking or resizing the screen. I had to shutdown the machine and now I have no GUI. I only get a black command-line interface. As some other posts suggest, I attempted: sudo service lightdm restart This doesn't work for me because it gets stuck at this point: Skipping profile in /etc/apparmor.d/disable: user.bin.firefox Skipping profile in /etc/apparmor.d/disable: user.sbin.rsyslogd * Starting AppArmor profiles [ OK ] Any ideas?

  • Collision detection problem in XNA

    - by Fantasy
    I'm having two problems with my collision detection in XNA. There are two boxes, the red box represents a player and the blue box represents a wall. The first problem is when the player moves to the upper side or bottom side of the wall and collides with it, and then try to go to the left or right, the player will just jump in the opposite direction as seen in the video. However if I go to the right side or the left side of the wall and try to go up or down the player will smoothly go up or down without jumping. The second problem is that when I collide with the box and my key is still pressed down the blue box goes half way through red box and and goes back out and it keeps doing that until I stop pressing the keyboard. its not very clear on the video but the keeps going in and out really fast until I stop pressing the key. Here is a video example:- http://www.youtube.com/watch?v=mKLJsrPviYo and Here is my code Vector2 Position; Rectangle PlayerRectangle, BoxRectangle; float Speed = 0.25f; enum Direction { Up, Right, Down, Left }; Direction direction; protected override void Update(GameTime gameTime) { // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); KeyboardState keyboardState = Keyboard.GetState(); if (keyboardState.IsKeyDown(Keys.Up)) { Position.Y -= (float)(Speed * gameTime.ElapsedGameTime.TotalMilliseconds); direction = Direction.Up; } if (keyboardState.IsKeyDown(Keys.Down)) { Position.Y += (float)(Speed * gameTime.ElapsedGameTime.TotalMilliseconds); direction = Direction.Down; } if (keyboardState.IsKeyDown(Keys.Right)) { Position.X += (float)(Speed * gameTime.ElapsedGameTime.TotalMilliseconds); direction = Direction.Right; } if (keyboardState.IsKeyDown(Keys.Left)) { Position.X -= (float)(Speed * gameTime.ElapsedGameTime.TotalMilliseconds); direction = Direction.Left; } if (PlayerRectangle.Intersects(BoxRectangle)) { if (direction == Direction.Right) Position.X = BoxRectangle.Left - PlayerRectangle.Width; else if (direction == Direction.Left) Position.X = BoxRectangle.Right; if (direction == Direction.Down) Position.Y = BoxRectangle.Top - PlayerRectangle.Height; else if (direction == Direction.Up) Position.Y = BoxRectangle.Bottom; } PlayerRectangle = new Rectangle((int)Position.X, (int)Position.Y, (int)32, (int)32); base.Update(gameTime); }

  • 5 Best SEO Strategies to Promote Your Website

    People nowadays use the internet and visit websites to search for any available information. Some users tend to use popular search engines like Google, Yahoo and MSN if they don't know the URL or the web address of what they are searching.

  • Ubuntu and surround sound

    - by keith
    I'm trying to connect my Logitech x.530 to my Dell studio 1558 and get 5.1 sound. I have 3 jacks and in Windows I automatically could switch between line in adn mic. Which means I could get 5.1 surround over these 3 jacks. Ubuntu does not realise that one of the three jacks should be switched to give sound to the center and LFE speaker. I tried all the tips in the forums, but nothing works. I can only select 4.0 sound in pulse audio. As the dell and the IDT 92hd89e chip for the sound are probably famous laptops I thought there must be someone who has similar issues in the 5.1 sound. I would like to stay at Linux but without this hardware support it's almost impossible.

  • LWJGL: Camera distance from image plane?

    - by Rogem
    Let me paste some code before I ask the question... public static void createWindow(int[] args) { try { Display.setFullscreen(false); DisplayMode d[] = Display.getAvailableDisplayModes(); for (int i = 0; i < d.length; i++) { if (d[i].getWidth() == args[0] && d[i].getHeight() == args[1] && d[i].getBitsPerPixel() == 32) { displayMode = d[i]; break; } } Display.setDisplayMode(displayMode); Display.create(); } catch (Exception e) { e.printStackTrace(); System.exit(0); } } public static void initGL() { GL11.glEnable(GL11.GL_TEXTURE_2D); GL11.glShadeModel(GL11.GL_SMOOTH); GL11.glClearColor(0.0f, 0.0f, 0.0f, 0.0f); GL11.glClearDepth(1.0); GL11.glEnable(GL11.GL_DEPTH_TEST); GL11.glDepthFunc(GL11.GL_LEQUAL); GL11.glMatrixMode(GL11.GL_PROJECTION); GL11.glLoadIdentity(); GLU.gluPerspective(45.0f, (float) displayMode.getWidth() / (float) displayMode.getHeight(), 0.1f, 100.0f); GL11.glMatrixMode(GL11.GL_MODELVIEW); GL11.glHint(GL11.GL_PERSPECTIVE_CORRECTION_HINT, GL11.GL_NICEST); } So, with the camera and screen setup out of the way, I can now ask the actual question: How do I know what the camera distance is from the image plane? I also would like to know what the angle between the image plane's center normal and a line drawn from the middle of one of the edges to the camera position is. This will be used to consequently draw a vector from the camera's position through the player's click-coordinates to determine the world coordinates they clicked (or could've clicked). Also, when I set the camera coordinates, do I set the coordinates of the camera or do I set the coordinates of the image plane? Thank you for your help. EDIT: So, I managed to solve how to calculate the distance of the camera... Here's the relevant code... private static float getScreenFOV(int dim) { if (dim == 0) { float dist = (float) Math.tan((Math.PI / 2 - Math.toRadians(FOV_Y))/2) * 0.5f; float FOV_X = 2 * (float) Math.atan(getScreenRatio() * 0.5f / dist); return FOV_X; } else if (dim == 1) { return FOV_Y; } return 0; } FOV_Y is the Field of View that one defines in gluPerspective (float fovy in javadoc). This seems to be (and would logically be) for the height of the screen. Now I just need to figure out how to calculate that vector.

  • How do I get my Mac to boot from an Ubuntu USB key?

    - by user11621
    If you select "USB" and "Mac" on this download page, it gives a series of command line instructions to make a USB key which the MacBook will boot into Ubuntu from. I've followed them to the letter two or three times on different USB keys, and it doesn't work. There's a very great deal of technical discussion about EFI etc. but this set of instructions seems to suggest it should just work, but it doesn't. Help? I'm increasingly unhappy with the more locked-down approach Apple is taking, and I'd quite like to start using Linux with a view to transitioning over to using it as my main operating system, but booting from the CD takes forever, runs slowly and I'm really hoping to get it moving off USB. Can anybody help me?

  • NetworkManager refuses to manage my WLAN interface

    - by user104167
    I'm using Ubuntu 12.10 with Gnome 3.6 on a brand-new Samsung NP900X4C. The installer detected the wireless adapter, took in the SSID and WPA passphrase, wrote these into /etc/network/interfaces and connected perfectly. Once installation was finished I wanted to switch to using NetworkManager to manage the wireless adapter, since this is much more convenient than fiddling with /etc/network/interfaces every time I find a new hotspot. Therefore I edited /etc/NetworkManager/NetworkManager.conf to set: [ifupdown] managed=true When I rebooted NetworkManager, the problems started: - The NetworkManager tray applet changed from saying device not managed to device not ready - I lost all internet connectivity as wlan0 would not associate to the Access Point - if I set managed=false in NetworkManager.conf and restarted both NetworkManager and networking services from the command-line, the Gnome desktop "semi-crashed" and lost all its Window Decorations, the panel, the launcher and basically became unusable. However if I restart the computer completely after setting managed=false, wlan0 once again works perfectly.
