Just recently upgraded to 13.04 and am having trouble running TF2 via Steam. Whenever I start Steam I get a dialog saying:     OpenGL GLX context is not using direct rendering, which may cause performance problems.   Every time I go to launch TF2 I get a dialog saying:     Could not find required OpenGL entry pint 'glGetError'! Either your video card is unsupported, or your OpenGL driver needs to be updated.   I tried updating my Nvidia drivers, hoping that would solve this issue but alas, it did not. I believe this issue is related to a fix I used to get Skype working with 13.04, specifically . Just a heads up I'm using GNOME Shell 3.8.  Let me know if you need anymore information about my system.

I am not able to play "Half-Life-2" on Steam + Ubuntu 14.04 . Error shown in message box on screen:      Could not find required OpenGL entry pint 'glGetError'!

I installed Ubuntu 14.04 on my Lenovo IdeaPad Y510P today. Everything worked fine, but after installing my graphics card driver the background became pixelated (Nvidia GeForce GT755m). I downloaded the driver through Additional Drivers and selected Version 331.113 (Proprietary, tested). It was using Nouveau before.  When I apply Nouveau it becomes clean again, but it is much weaker when I open games, it gives me very low FPS even in Counter-Strike. With Nvidia driver FPS and everything else seems fine, except things look pixelated and when I minimize windows and maximize again, the window goes black.    I attempted to solve the problem myself by removing the old Nvidia driver and manually installing the latest version, but it did not help.  Please let me know if you need more details.

[SOLVED] I managed to fix the issue by uninstalling the proprietary AMD drivers, rebooting, starting Steam letting it update, reinstalling AMD drivers, reboot. It seems to be working and I can now play all my Steam linux games. I just installed Ubuntu 13.10 64bit on my main PC. I also installed Steam (.deb from ). The install went without errors. On running Steam, nothing happens. I run Steam from the terminal and receive two segmentation faults, always occurring on different lines of Steam.sh when I run Steam: /home/samathy/.local/share/Steam/steam.sh: line 755: 11111 Segmentation fault   /home/samathy/.local/share/Steam/steam.sh: line 755: 11239 Segmentation fault   The rest of the output on the terminal is just dump-saving text. I can't see anything about GLX issues, or locale issues (they seem to be popular issues with steam) I'm running Ubuntu 13.10 64bit with Xubuntu (installed after the Ubuntu install.) My specs are as follows: AMD FX 6350. AMD HD7870 (With AMD proprietary beta drivers) 12GB DDR3 Samsung 840 EVO 120GB. This problem is a little weird to me because Steam runs fine on my Ubuntu 13.10 + Xubuntu-desktop, Intel Atom N270 netbook without any fiddling, I can even run games. I've googled a lot and only really found solutions to other steam issues, not my own. If anyone could help, that'd be wonderful. Thanks! edit: I should mention that I've tried doing ~$steam --reset  It does not produce errors its self, but also doesnt solve the problem either. I have also tried installing Steam from Ubuntu package manage, but that results in the same errors.

Update  This has been confirmed resolved in a later version 376.33 and possibly the update prior.     Okay, I recently did a computer update. I used to run Blender 2.77 on a Dell desktop (5 GB RAM, 2.7 GHZ, Windows 8, build in graphics card). Since that computer wasn't fast enough for my preference, I saved up and got a new gaming laptop - the Asus ROG GL552 (Windows 10, 16 GB DDR4 RAM, Nvidia GeForce GTX 960M with 4 GB DDR5 RAM, 2.6-3.5 Ghz, and quad-core intel processor). That laptop has been known to have outdated drivers, so when I got it, I updated it to up to date Windows 10 drivers.  As soon as I started Blender, I immediately noticed its speed. Even doing simple things, like clicking buttons, or rotating the view with the middle mouse button, took too long to register in the program. I tried changing some User Preference System settings, but that didn't really help much. And the hardware seems to be fine - the render is lightning fast (renders the startup scene in under .1 second; it's just laggy when loading the uv screen), so I don't know why it's like this, or what to do. Also, I ran Blender 2.77 on this computer, and it was also slow (although it was fine on my previous computer).  It could be an issue with drivers perhaps (or maybe OpenGL?), but I ran Unreal Engine 4, and had none of the same issues - the speed was pretty decent on that; so I'm not sure why Blender would be so slow. Any help is appreciated - thanks guys!

I got black screen like said in this post :   Friend's list, Library, everything show me a black screen.  The answer in the link i posted can't work anymore : a part of this answer is to put Windows Version : Windows XP in wineconfig  As of now, steam can't be launched with Windows XP. So I have to put Windows 7 or 10, and the "-no-cef-sandbox"  argument seems to be useless alone.  I can add that i also tried to put d3d11 in Native Windows without success. Someone could help ?

I recently installed 14.04.  But now I need a new driver for my nVidia GeForce GT 630. The former driver was rejected as not compatible with the 64-bit. I found that other driver and when I wanted to install it in the terminal with sh I was called first to stop the x-server. It cannot be installed with running x-server.  So how do I install them?

Just bought a Geforce GTX 660 and replaced my Radeon HD 5870 (it finally died after 3 years). I'm having terrible problems getting the video card to work. As I only had command line options so far I've ran:  (purged fglrx*)  then  sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-331  and then I started getting low graphics mode errors. did some searching on my tablet, and I tried several things but what finally worked better was:   sudo apt-get install bumblebee bumblebee-nvidia  However now that I'm logged into my computer finally, I have no access to terminal, no access to the top bar, and hitting Super Key does nothing, alt-f2 does nothing, and I only can post because I tried running WoW and it had an error and the error report opened a link.   All I can see on my desktop is my wallpaper and desktop icons. I can CTRL+ALT+F1, and navigate to the downloaded official nvidia driver, however that won't run because of x-server, and I can't run it from my desktop.   Can anyone help me?

After it was reinstalled, updates downloaded but it won’t start even from the terminal. This is the error message it gives:  Running Steam on ubuntu 16.04 32-bit   STEAM_RUNTIME is enabled automatically   [2016-04-25 09:12:35] Startup - updater built Mar 31 2016 19:10:48   SteamUpdateUI: An X Error occurred   X Error of failed request:  BadValue (integer parameter out of range for operation)

This is the third reinstall of Ubuntu 14.04 I have done today.  I just bought a laptop with an Core i3 processor and an Nvidia GeForce GT 840M graphics card.  I have installed the Nvidia driver using their .run file, and also following tutorials, and it just doesn't work. When I check in the terminal which GPU I am using it says "i915" instead of "nvidia".

After upgrading from 12.04 to 14.04 I could log in to my X session (albeit with really low graphics). While trying to fix the graphics, I managed to break the X session.  Now, after typing my password in the unity-greeter, the items disappear and I can only see the desktop background and the pointer. This happens for every user. I can still log in in tty's. How can I solve this?  Also, I cannot seem to be able to install nvidia-current as it tries to install nvidia-304 and it depends on old video-abi libraries. Is there a way to tell the package manager that nvidia-current should use a newer version?

I currently have 2 R9 280's and according to blender all GPU's with the new OpenGL and GCN 1ste gen are supported. But in blender 2.79 and 2.82 I can't seem to use it in any way. I know AMD is not that great but I am saving up for a 2060 and the dual R9 280's should work for now. can someone please help me to fix this. and command line codes I have to run or scripts I can use.

I had the beta drivers running previously and after a standard update it stopped working. What I've tried so far:  sudo apt-get remove --purge fglrx*   Then downloaded drivers from Amd website and unzipped it and ran:  sudo ./amd-driver-installer-catalyst-13-4-x86.x86_64.run --buildpkg Ubuntu/trusty sudo dpkg -i fglrx*.deb   After this the Ubuntu  guide wants to make this:  aticonfig --initial   and it returns:  Unable to open /etc/ati/control, please reinstall the driver. aticonfig: No supported adapters detected   The adapter is 280x and as said, it worked previously with the same drivers and with the same installation procedure.  Any ideas?

I have been on quite the odyssey trying to get steam to work.   I am using Ubuntu 15.04 and the linux 4.0.5 kernel. System specs:  Intel haswell quad core CPU AMD Radeon 7870 Graphics Samsung 850 EVO SSD 16GB Memory  I was able to get steam to work in 14.04LTS, but I had other problems with that version; namely flash issues in chrome. So I updated to 15.04 and my system is more stable (except for steam, there is always something...)  I have tried removing various lib files to no effect. I have removed and installed steam a few times and it doesn't appear to be working.   I tried switching to the proprietary drivers, but that causes my system to hang when it boots. In order to fix it I completely removed and purged fglrx from my system. I attempted to reinstall the proprietary drivers via command line according the ubuntu page instructions, and ran into the same error, so I am stuck with the open source drivers.  I can only assume that my card is no longer supported by the proprietary drivers, which is frustrating.   Before I removed the proprietary drivers I got the same error as these guys:   Now that I have removed the proprietary drivers I am getting missing lib errors, which I guess is not surprising:  libGL error: unable to load driver: radeonsi_dri.so libGL error: driver pointer missing libGL error: failed to load driver: radeonsi libGL error: unable to load driver: swrast_dri.so libGL error: failed to load driver: swrast  I am about ready to give up and am seriously considering buying an Nvidia card. If anybody has any suggestions on what else I can do, I would really appreciate it.

I am currently using Ubuntu 14.10. Steam is showing up in the Ubuntu Software Center, but when I click on it it says:      Not found   There isn't a software package called "steam" in your current software sources.         Is there a fix for this? Am I the only one having this problem?

I recently made the switch to Ubuntu. Everything on my laptop works fine except my hybrid graphics card. It is Intel graphics combined with Nvidia GeForce GT650M. I tried Bumblebee, but primusrun doesn't work (segmentation fault, core dumped) and optirun works with glxspheres64, but steam games look worse with optirun than with Intel graphics (e.g. Surgeon Simulator 2013 runs fine with Intel and hangs a lot with optirun)   I tried Nvidia Prime, but it gives me a black screen on startup after install, so I can't do anything and have to power off my PC with the power button. I also tried nvidia-prime 0.5 on Ubuntu 14.04, and then I get 'low-graphics mode' and I can't get to Unity.
