• Dim (NEARLY blank) laptop screen, secondary screen works - why?

  - by LIttle Ancient Forest Kami

  My laptop screen is (almost) black while my secondary screen is fine. I believe it to be backlight / brightness related. Problem description it starts when I start the laptop system loads and works fine, just screen has problems I can see the screen though very faintly / dimly - it's hard to see anything which ain't very white e.g. starting screen has big Thinkpad logo in white, large font - I can see it, though very dimly second screen works very well Official backligtht debugging: using acpi setting as prescribed there for Thinkpads didn't help I can see an entry in /sys/class/backlight/ and it changes when I press hotkeys for brightness (current backlight power for instance goes up or down) acpi-off didn't helpm neither did acpi_backlight=vendor Hardware data Laptop is Thinkpad Edge with glossy screen. 4 processors, 2 cores, exemplary CPU data from cat /proc/cpuinfo reports Genuine Intel i5 (M 480 @ 2.67GHz). OS is Ubuntu Lucid, 10.04 LTS, 64-bit, with Linux generic kernel (2.6.32-44) and GNOME 2.32.2 (though I doubt there lies the problem). $ lspci | grep VGA 01:00.0 VGA compatible controller: ATI Technologies Inc M92 [Mobility Radeon HD 4500 Series] $ lshw -C display *-display description: VGA compatible controller product: M92 [Mobility Radeon HD 4500 Series] vendor: ATI Technologies Inc physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 32 bits clock: 33MHz capabilities: pm pciexpress msi bus_master cap_list rom configuration: driver=radeon latency=0 resources: irq:33 memory:c0000000-dfffffff(prefetchable) ioport:2000(size=256) memory:f0300000-f030ffff memory:f0320000-f033ffff(prefetchable) Driver I was NOT running any proprietary drivers, just checked with "Hardware drivers". There is one for ATI that is suggested there, though I didn't need it so far. UPDATE: changing the driver to proprietary one (ATI/AMD FGLRX) didn't help. Tried and failed Resetting / running on power or battery / charging / getting rid of static electricity / warming up *doesn't help* This is NOT a blank-screen problem, at least it isn't following official Ubuntu black-screen diagnostics - I can see my screen, though barely. What I will try next: - check last updates I've made - IIRC I am running on nomodeset already, but will verify this Any ideas how to proceed best? What is most probable cause?

• Windows 7 XPS Document Writer has stopped working

  - by jamie

  I have successfully used the Windows 7 XPS Document writer for quite a while under windows 7 (64 bit). Now however when i try to print i get prompted twice for the output file name and then get different error messages depending upon the application being used. e.g. Notepad gives a 'The I/O operation has been aborted because of either a thread exit or an application request'. I have disabled and reenabled the XPS facilities of windows features and have similiarly removed and readded the printer. But the end result is the same. I've uninstalled all applications i have installed since the time when i know it worked but this also has not made any difference. Suggestions please!

• Unity, changing gravity game & stopping character when he hit a wall.

  - by Sylario

  i am currently working on a 2d puzzle game in the unity engine. One of the aspect of this game is the possibility to rotate the level of 90°. It also rotate the gravity. The main character is not directly controlled by the player, but instead fall when the level is rotated. When the main character hit a wall, he should stop to move. If i do not stop it, it kind of blink ans shake against the wall. To stop it i detect collision and depending on the current rotation state, the player will stop at "vertical" or "horizontal" tags when a OnCollisonEnter occurs. I must do that because when the player fall on his relative ground, He must not stop like if he had touch a wall. My problem is the 'side' of platform, or the 'top' of wall, they use the same tag and thus do not give the correct tag to my character. I tried to put a very small invisible box on top/side of elements but the collision occurs nevertheless. It seems when the player falls and hit something he go through a bit before being replaced at correct position by unity. Is there a way : 1 ) to doesn't stop my character but to make it appear immobile on screen 2 ) To detect a "i cannot move anymore" collision other than by using collision?

• What are some ways to separate game logic from animations and the draw loop?

  - by TMV

  I have only previously made flash games, using MovieClips and such to separate out my animations from my game logic. Now I am getting into trying my hand at making a game for Android, but the game programming theory around separating these things still confuses me. I come from a background of developing non game web applications so I am versed in more MVC like patterns and am stuck in that mindset as I approach game programming. I want to do things like abstract my game by having, for example, a game board class that contains the data for a grid of tiles with instances of a tile class that each contain properties. I can give my draw loop access to this and have it draw the game board based on the properties of each tile on the game board, but I don't understand where exactly animation should go. As far as I can tell, animation sort of sits between the abstracted game logic (model) and the draw loop (view). With my MVC mindset, it's frustrating trying to decide where animation is actually supposed to go. It would have quite a bit of data associated with it like a model, but seemingly needs to be very closely coupled with the draw loop in order to have things like frame independent animation. How can I break out of this mindset and start thinking about patterns that make more sense for games?

• Symantec Backup exec 2012 for SBS - moving data to offsite drives

  - by Will Lennard

  Can anyone advise how best to run the following strategy, or even if it is possible/sensible strategy? I am looking to backup an SBS server using BE2012 where the data is backed up on a weekly full backup, with subsequent daily incrementals till the end of the week, a fresh full backup will then be taken the next weekend, and the cycle repeats for 4 weeks, thus 4 full backups with incrementals. This months worth of backups will then be moved off to an offsite store via USB drive for safe keeping. Is this viable, sensible, or am i just a bit crazy? All ideas are welcome.

• Is there a NVIDIA driver (for a 7-series card) that will actually work for 12.10?

  - by DS13

  I see many similar topics on this, but I've tried all their suggestions, and nothing has worked. ISSUE: I do a clean install of Ubuntu 12.10. Boots fine with the “nouveau” graphics driver – graphics are very slow and choppy. The three other driver options in Ubuntu (official NVIDIA drivers), all result in a variation of the black screen on boot up. There will be NO access to a command line/GUI in anyway what-so-ever (tried every option recommended out there, but the system is unusable at this stage). I can only reinstall, and try different drivers…and I only ever get one shot at it. QUESTIONS: Does anyone know of a NVIDIA driver that will actually work with a Nvidia GeForce 7350LE? Or a 7-series card in general? This is my second computer, and I’m just trying to get a working install of Ubuntu on it. I don’t want to put much money into it, as I have seen Ubuntu run great on much older/less capable machines. I’ve got a decent Intel processor (2.3Ghz), 2GB of RAM, 320GB hard drive, 32-bit architecture, and there is no other O/S installed. It appears as if the graphics card is holding me back. Should I just buy a cheap graphics card (non-NVIDIA) to put in as a replacement? TRIED SO FAR: -all drivers available in Ubuntu *all fail -manual install of some different NVIDIA drivers *all fail -also tried installing the generic kernel, Nvidia driver doesn't work in 12.10 *no difference -every method suggested to at least get a command line after switching to a NVIDIA driver *all fail

• libGDX using Stage and Actor produces different camera angles on desktop and Android Phone

  - by Brandon

  libGDX using Stage and Actor produces different camera angles on desktop and Android Phone. Here are pictures demonstrating the problem: http://brandonyuh.minus.com/mFpdTSgN17VUq On the desktop version, the image takes up most all the screen. On the Android phone it only takes up a bit of the screen. Here's the code (not my actual project but I isolated the problem): package com.me.mygdxgame2; import com.badlogic.gdx.*; import com.badlogic.gdx.graphics.*; import com.badlogic.gdx.graphics.Texture.TextureFilter; import com.badlogic.gdx.graphics.g2d.*; import com.badlogic.gdx.scenes.scene2d.*; public class MyGdxGame2 implements ApplicationListener { private Stage stage; public void create() { stage = new Stage(); stage.addActor(new ActorHi()); } public void render() { Gdx.gl.glClearColor(0, 1, 0, 1); Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); stage.draw(); } public void dispose() {} public void resize(int width, int height) {} public void pause() {} public void resume() {} public class ActorHi extends Actor { private Sprite sprite; public ActorHi() { Texture texture = new Texture(Gdx.files.internal("data/hi.png")); texture.setFilter(TextureFilter.Linear, TextureFilter.Linear); sprite = new Sprite(new TextureRegion(texture, 0, 0, 128, 128)); sprite.setBounds(0, 0, 300.0f, 300.0f); } public void draw(SpriteBatch batch, float parentAlpha) { sprite.draw(batch); } } } hi.png is included in the above link Thank you very much for answering my question. I've spent 3 days trying to figure it out.

• "System call failed" error when trying to open "My Computer" etc. under the Start menu! What is happening?

  - by verve

  When I go to the start menu I can load program icons but if I click on Documents, My Pictures, My Computer, Default Programs...all the options on the right part--I get "System call failed". How do I solve ths? Is my HD failing? Also, I don't know if it's connected but yesterday my uTorrent stopped working in a way it has never done before. I'm not able to download torrent files. In the program I get "socket unreacheable..." Also, for the last 2 days my internet has been super-slow. I checked Kaspersky for viruses. It says: "No active threats". Windows 7 64-bit.

• how to set global PATH on OS X?

  - by lajos

  I'd like to append to the global PATH variable on OS X so that all user shells and GUI applications get the same PATH environment. I know I can append to the path in shell startup scripts, but those settings are not inherited by GUI applications. The only way I found so far is to redefine the PATH environment variable in /etc/launchd.conf: setenv PATH /usr/bin:/bin:/usr/sbin:/sbin:/my/path I coulnd't figure out a way to actually append to PATH in launchd.conf. I'm a bit worried about this method, but so far this is the only thing that works. Does anyone know of a better way?

• Phantom Local Disks appearing in my drive list

  - by Paul

  I seem to have several phantom Local Disks mapped to different letters that are of 0 bytes in size. Strangely, they do not show up when I view my drives through Windows Explorer. But if I open an application such as ACDSee Pro or MS Word and then go to open a file I can see all these Local Disks mapped to different letters. This means when I plug in my external hard disk it ends up mapped to letter R instead of its usual G which messes up any programs I have pointing to it by default. How did they get there and more importantly, how do I get rid of them? I'm on a Window 7 Home Premium 32 bit machine.

• Choosing a Linux distribution

  - by Luke Puplett

  Dangerous territory with this question so please try to be impartial and instead focus on what to look for when choosing a Linux distribution. I'm completely new to Linux. I thought it'd never happen but I need to have a Linux box to play with and I have a spare fanless Atom PC (32-bit only). I'll be using the machine as a non-commercial hobby server, the trouble is, I don't even know how to compare Linux distributions and why people pick one over another. If anything, I want to have an easy install from USB stick. My question is: what do you look for when choosing a (free?) Linux distribution for a server? If you can, please explain what sorts of things actually differ between one and another without saying which you think is better, just the facts. The way I see it, Linux as a server is just an SSH console and I find it hard to imagine what could be different between one and another.

• What's normal Taskbar behavior (windows)

  - by Erik

  I'm a fairly new user to windows, and Vista is my first version. I'm a bit confused about the taskbar -- either its behaving oddly or I'm just confused, or I've broken something. When I've got a lot of windows on screen, I thought that clicking on a window's taskbar icon would bring that window to the front. I thought it had been doing that in the past, but I'm not entirely sure. When I click it, it just flashes, a second click minimized, and a third click reopens and brings it to the front. Is this normal?

• My laptop suppose to have 6 GB ram but it's only 2 GB installed

  - by monablo

  My laptop is supposed to have 6 GB ram but it only detects 2 GB of it, so I don't know what to do. I searched the web for answer and what i get that there's 2 possible problem: 1- That 4 GB ram card is broken and not working 2- or the 2 ram card have a different path so the windows chose the path of the smaller ram card which would be the 2 GB ram I don't know what is the path in first place so I really don't know what to do. How would I troubleshoot, and work out why the 4 GB stick is not being detected? My laptop's specifications are as follows: Windows 7 Home premium 64- bit Operating system processor : intel (R) core(TM) i7 CPU Q740 @1.73 GHz 1.73GHz installed memory(RAM) : 2.00 GB (but it suppose to be 6 GB -_- ) My laptop is Dell and it's Model N5010

• PHP + IIS7 + X64 OS (Windows 7 or Server 2008)

  - by Eric

  I'm going to answer my own question here, but I thought this might be important enough to post so that it would be indexed for the next person who runs into my situation. Problem: I can not seem to get PHP code to execute on a x64 bit version ofIIS7, whether it be in my desktop, Windows 7, or the application's final destination on Windows Server 2008. Every time I try and look at a test php document to confirm installation, I only see the source code. I've followed the documentation from PHP, from iis.net, blogs, howtos, just about anywhere I can find that Google would send me. I tried the web installer, tried manual installations instead of the MSI, tried version 5.3.5, tried version 5.2.17, but no matter what, the code would never execute. I even tried registering .eric files with PHP FastCGI Module, but same result, php source code only.

• Change ownership of directory and all contents to a new user from root.

  - by Andrew Fashion

  I created a website under /var/www/html/ all under root, all images, files, .htacess, directories, etc... I uploaded and configured everything as root. I want to make it it's own username/password so it's not owned by root. I currently do not have the user account made either, I want to also setup FTP for the user account. There is also about 30GB of images in the folder as well. How can I go about changing all of this? I am running CentOS 5.5 64 bit. Thank you!

• Browsing freezes after installing SP2 on Vista

  - by n21jc

  After installing SP2 on Vista 32-bit HP laptop, all browsers (Firefox, IE, Maxthon) periodically freeze randomly. It occurs when opening a new webpage. It might happen after 45 minutes of browsing, or 3 minutes. The only way to get out of it is to right click the taskbar, "end program", and say "close now" when it tries to search for a solution. Or occasionally, I have to hard reboot. It doesn't seem to correlate with any one particular type of webpage, but I'm assuming that something being loaded doesn't play well with my system. I would uninstall SP2, but it fixed several even more annoying system problems I'd had with my computer.

• How to copy/paste LARGE amounts of text in Windows

  - by Johnson

  I am not sure if this is more suited for Superuser or Stackoverflow, but here goes... A little bit of background: I'm learning SQL and was trying to make a very large table which I could use for optimization tests. Something generic with random values. I created a little Java program to do just that, and was able to put out a text file with 100,000 lines, each line being an SQL INSERT statement for a new random record. However, with anything much bigger than 100,000 lines, I had problems either opening/using the text file in any text editor, or copying/pasting the text to the windows clipboard and then into SQL Developer so I could execute it as a script. I'm probably overlooking something really obvious, or doing something really stupid. There has got to be a better way to do this, but I couldn't find anything through Google or Stackoverflow or Superuser. Thanks!

• SSH and Latent Connections (e.g., satellite connections)

  - by user71494

  Most of the week I live in the city where I have a typical broadband connection, but most weekends I'm out of town and only have access to a satellite connection. Trying to work over SSH on a satellite connection, while possible, is hardly desirable due to the high latency ( 1 second). My question is this: Is there any software that will do something like buffering keystrokes on my local machine before they're sent over SSH to help make the lag on individual keystrokes a little bit more transparent? Essentially I'm looking for something that would reduce the effects of the high latency for everything except for commands (e.g., opening files, changing to a new directory, etc.). I've already discovered that vim can open remote files locally and rewrite them remotely, but, while this is a huge help, it is not quite what I'm looking for since it only works when editing files, and requires opening a connection every time a read/write occurs. (For anyone who may not know how to do this and is curious, just use this command: 'vim scp://host/file/path/here)

• How to start a Software Company

  - by MeshMan

  I've always been interested in wondering how software companies happen. I find it extremely difficult once you're tied down with car, house, life etc. Funding is always the biggest concern. To make this a bit more specific, I see two types. Those offering a product/service or those offering a consultancy company. One things that bugs me about the product/service kind is that we all know how burning the candle at both ends is extremely exhausting. Coding for 8-10 hours in the day and then code in the evenings on your own stuff, doesn't last long. No matter how passionate you are about your idea, simply put, coding day and night is a recipe for burn out. Is this a defeatist attitude though? Can it be balanced? A consultancy kind isn't as tricky in my honest opinion. I think once you have spent years and years in the industry building up relationships, contacts from contracting or moving around, and of course, being involved in the community, then landing your first project as a consultant I'm sure is easier than the product/service kind. I'd imagine friends then could join you as you take on bigger company projects, like an Agile implementation or TDD training, then off you go gaining bigger things. Could you please specify which company type you're answering if you can't contribute to both. I'd like to hear everyone's experiences or ideas on any level for software company start-ups.

• Can't select text with mouse in Word / Office 2007

  - by asc99c

  I'm having a very weird problem here for the last few months. In Word, and in fact all programs from the Office 2007 suite, I can't drag the mouse pointer to select text. I can click at a point in the text and the cursor moves correctly to that point. If I double click, the word under the cursor is selected, and triple clicking selects the whole line. However if I hold the mouse button down and drag the mouse, no text is selected. Occasionally the problem disappears and everything works fine, but it then reappears a few minutes later. Text selection with the mouse works everywhere else (Firefox, PuTTY, OpenOffice), just not in Office. The only addins are Google Desktop Office Addin, and Person Name (). For info it is Office 2007 SP3, running on Windows 7 64-bit.

• Need to automount dvd or cdrom at fixed mount point in Ubuntu 11.04

  - by Lindsay Haisley

  Ubuntu 11.04, by default, automounts a cdrom or dvd at /media/<vol_name>. I need to make the automounting system use a fixed name instead of the volume name for all CDs or DVDs inserted into this particular drive, e.g. "/media/op-drive0". A bit of searching turns up pretty much the same solution I used, successfully, on an older, gentoo box, which is to create an fdi file for hal, along the lines of the instructions at https://bbs.archlinux.org/viewtopic.php?id=91450. This doesn't seem to work on this box. Other sources say to use the gnome-mount utility to set the mounting properties. Ubuntu 11.04 doesn't know about the gnome-mount program. Any ideas?

• Cannot access windows share

  - by Wrigley

  I have an accounting program specifically tailored to the IT industry, its called Fincon (exe based). It basically works on a client to server directory base system. the server is currently running on a windows 7 machine with a NTFS partition. I have installed Wine. Have the shared Windows directory mounted with what I assume is the correct command for such being (mount -tsmbfs //servername/sharedir /mnt/fincon -0 usename=username,password=password). I can see the shared dir although it does take a bit long to access it on the Ubuntu machine via the mapped directory but instant via normal network browsing. I have also set up the mapped directory to my D: drive in Wine and have pointed the fincon.ini to read server field from D: directly. Here's my issue, it seems that for some odd reason I cant write to the mapped directory from Ubuntu, yet I can with my Windows machines, the permissions are set correct on the Windows 7 share and I really dunno what I'm missing. I'm quite a Linux noob just switched yesterday. Thanks guys for any help in this would be quite appreciated. As I'm pulling out my hair here and really want to migrate my work PCs to a Linux OS as it just gives less issues than Windows does ever.

• Why is Windows 7 so slow to log-on when my Wireless USB dongle is plugged in?

  - by Sam

  I'm using an Edimax Wireless USB dongle (model EW-7711UTN) on Windows 7 64-bit. The dongle works brilliantly (it was truly plug-and-play) except for one thing. I've noticed that if the dongle is plugged in whilst I'm logging on to Windows it introduces a massive delay - after I type in my password and hit enter, Windows shows the "Welcome" screen, then the screen goes black for 2 minutes or so (with just the cursor showing) before finally displaying my desktop. If I unplug the dongle before I enter my password, Windows goes straight to my desktop. Even though the dongle didn't appear to need drivers for Windows 7, I did try downloading the latest ones from the Edimax website, but that made no difference.

• Easily manage vsftpd virtual users?

  - by Phil

  I have a vsftpd server configured with many virtual users. logins are stored in a Berkeley DB file One configuration file exists for each user to define his permissions (read-only or read-write, home directory, etc.). To do that, I use the user_config_dir parameter (set in vsftpd.conf). I am wondering if it would be possible to manage these virtual users from a simple GUI (such as web interface). I have found some tools but they are limited to generic vsftpd configuration, not virtual users management. Otherwise, PAM-MySQL seems to be a good way to manage users efficiently but only username/password and logs can be stored in database, not permissions. Finally, I've found this thread, but the solution is a bit awkward... Is there any way to easily manage the vsftpd users ?
