I have downloaded Ubuntu 14.04 and wanted to try some OpenGL programming. My laptop has switchable graphics technology (Intel HD Graphics 4000 and AMD Radeon HD 8570M). I thought that it'd be better to install proprietary drivers and take advantage of OpenGL 4+ so first I installed the drivers by typing sudo apt-get install fglrx-updates, then I rebooted my pc. However, after boot, low-graphics error came up instead of login screen.  I didn't give up and tried searching google on my other computer. I tried almost everything possible, yet it still looks like my graphics is not being recognized.  It's worth noting that I have linux-headers installed and am using 64bit version of Ubuntu. Also, when I uninstall the fglrx driver, everything works fine again.  Here's what I already tried:   Reinstalling the drivers (complete purge). Entering low-graphics mode and typing amdconfig --initial. Installing the newest drivers drivers from amd.com (I also tried beta drivers; no luck). I switched LightDM to GDM, still no luck (it completely broke my Ubuntu installation).   Thank you for any suggestion.  EDIT: By reading some log files I came to a conclusion that the greeter fails to start. I just don't know why.  EDIT 2: I installed GDM once again. Now it boots to console without showing any error. I tried to log in and type startx and it says Caught signal 11 (Segmentation failed).

I am planning on doing a fresh install of Ubuntu and want to know what is the correct way to install ATI Catalyst Video Driver?      There are multiple valid answers for this question spanning over several versions of Ubuntu. For your convenience an index of each below:

My laptop computer has a Nvidia video card and runs Ubuntu 12.04 LTS 64-bit. During an upgrade yesterday it seemed as a new Nvidia driver version 304 (if I remember correct) was installed. After upgrade and reboot, I opened the Additional Driver tool and found that the Nvidia driver version 304 was in use. So far so good.  However, the Additional Driver tool also reported that there existed a Nvidia driver version 319 and that this driver version was recommended. I then selected to change to this recommended driver, the driver was downloaded and installed, I rebooted the system and ended up with a black screen and a command shell.  How to change proprietary Nvidia video driver using the command line and revert back to the previous version that worked on my system?  (A second question: How can it be that a video driver that apparently does not work was recommended?)

[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.

I've installed the  (beta) following the step in  for Ubuntu Quantal Quetzal. My system is 64 bit and my graphic card is an ATI RadeonHD 6670, this g.c. is Officially Supported (Catalyst &amp; Open Source), you can confirm that from this .  I don't have any problem, except the AMD testing use only watermark. I see the following frame in any stage into the OS (logged, unlloged, etc.) except in the terminals.     I found different versions of how to remove this image, but this change according to the system, so I want an answer from this popular (trusted) site.   How to solve this issue in Ubuntu 12.10 32b? This procedure is different in a 64b system?

I'm trying to update my graphics card.

I'm using Ubuntu 16.04 and there's no fglrx! What happened?

I have an MSI Radeon HD 7850 card. MSI provide no Linux support, and the AMD driver gives me an Unsupported Hardware watermark that does not show up in screenshots.  I uninstalled the proprietary driver and found that Unity 3D no longer works, and I really only picked Ubuntu because of the excellent shortcuts provided in the recent versions.   Trying to locate the open source driver has been a pain for me. According to the documentation I have read it is pre-included in Ubuntu 12.04, yet there is no Unity 3D support. I tried using the newest drivers from AMD's website, but that also had the watermark.  Does anyone know how I can get the open source driver? If not, does anyone know how to remove the watermark. I'm on the verge of going back to Windows.

To install the graphics driver I need to exit GUI / Gnome and go to the terminal. How can I do this in Ubuntu 18.04? Ctrl(STRG)+Alt+F1...F7 does not work, neither on the desktop, nor on the login screen...

I installed Ubuntu 18.04 After installation, I rebooted the computer, entered the grub menu, pressed e in ubuntu added the nomodeset option and Ubuntu presented the Gnome interface in a resolution of 1024X768 telling me: Unknown Display. So my question is how to install the drivers for my NVIDIA GTX 1050 graphics card

I have a Samsung NP-QX411. It has two graphics cards, Intel and nVidia. The Intel drivers were quickly found and is fully functional. But nVidia, I have tried installing several drivers in different ways. But I can not run it without success. I do not understand how Ubuntu has by default the switch Hybrid Graphics option. What should I do?

Ok, I'm a total Linux noob. I was able to install 12.4 without issue, except that it says in the system settings that the graphics card/driver is "unknown".  I have NVIDIA GeForce FX 5200, and have not been able to get it installed. I've found the driver at NVIDIA but couldn't figure out how to actually install it. I found instructions that used apt-get to automatically find the current driver and install it, and that came close. At least then it showed up in the 3rd party drivers list. It said it was installed but not being used? And I was unable to find out why that might be, or how to get the system to use it  Two questions: 1. CAN/SHOULD my graphics card work with 12.4? 2. If so, HOW?  I'm running a 100% fresh install, so what's the step-by-step from there?

The NVIDIA graphics driver on this PC is several versions out of date, so I went to upgrade it due to an unrelated issue. I went to the NVIDIA website, downloaded the 64-bit Windows 10 driver for the GT 720 GPU. I ran the installation as you normally would only to be met with the error "NVIDIA Installer Failed", and it told me the "Graphics Driver" failed to install.   Now I only have one usable monitor, the other is not detected, yet it turns on briefly as Windows initially loads the desktop.  What I Have Tried  Clean Installation  This is the first thing I tried, I restarted the computer, waited a while, and then I ran the NVIDIA driver installer, I selected "Custom Install", and then I ticked the "Clean Install" checkbox. This failed in the same way as before. Note, I also tried "Run[ning the updater] As Administrator".  Windows Update  I opened Windows Update to check for updates, since this can often fix failed driver installs. It said there was a NVIDIA driver update available, so began the update process. This failed with the error "0x80070003". I tried again, it failed again.  Manual Driver Install  From device manager, I right clicked on the GPU, and clicked "Update Driver Software", I opted to browse for driver files, with "Check subfolders" checked, and navigated to C:\NVIDIA\DisplayDriver\368.39\ and clicked "OK". This failed with "Code 28".  Manual Driver Install (Automatic)  Same as before, except I let Windows find the driver online automatically, I presume it found the same files I had already downloaded, and downloaded them again. This failed.  I am still stuck with one working monitor, reduced graphical performance, and am unable to install the NVIDIA driver.  This is my work PC, so I don't have a huge amount of time to reinstall Windows, so I'd rather not do that, as I have various customisations in place, and lots of programs installed. It'd take a long time for me to do all of that again.    EDIT: More Info  There are no NVIDIA listings under "Uninstall a Program" in the Control Panel. Yet the "NVIDIA Control Panel" app is still in the start menu, but does not start. I believe that is because there are just three DLL files in C:\Program Files (x86)\NVIDIA Corporation\coprocmanager, and no other files/directories in coprocmanager's parent directory.  When the driver is installing, my second monitor starts working, and then stops when the installation fails.  When the driver is installing, it briefly appears as "NVIDIA GeForce GT 720" in Device manager, after it fails, it goes back to being labeled, quite simply, "Display".  Tried running...  PsExec.exe -i -s "C:\NVIDIA\DisplayDriver\368.39\Win10_64\International\setup.exe"   ..to no avail.  PC Specs (from Speccy):   Custom build NVIDIA GeForce GT720 (not from Speccy, since it just lists the monitor under Graphics).

I recently updated the drivers for my NVIDIA GeForce video card to version 364.72 (or other version in the 364.xx series), and I'm now experiencing issues such as the following:   Games or other graphically intensive applications crash or hang I get BSODs that are associated with the graphics driver, e.g. nvlddmkm.sys or dxgkrnl.sys Graphical glitches such as missing or misplaced text or icons, display corruption, or a black screen occur The graphics driver crashes regularly, with the message "Display driver [...] has stopped responding and has recovered." The fan on my graphics card spins up to high speed, or the card makes excessive noise   Reinstalling the graphics driver did not help. What's going on?     This question comes up often and the answers are usually the same. This post is meant to provide a definitive, canonical answer for this problem. Feel free to edit the answer to add additional details.

I just ordered the Nvidia GTX card. I have a dilemma, though. Should I keep using the driver which is available in "additional drivers" in Ubuntu, or should I install the driver from the Nvidia site?  So which driver is the best for me?

To summarize the answer: switching to proprietary drivers should work, but the artifacts disappeared for me even on the free drivers now.  Update: since switching back to the proprietary AMD driver (fglrx), I haven't seen these artifacts.  Occasionally I see artifacts instead of correctly rendered characters:    For now I have only observed this in Firefox.  The characters become normal once I select the text.  What's the issue here and how can I solve it?  Graphics card:  AMD Radeon HD 7790 Driver: radeon (free) -> now I'm no fglrx and am not seeing the artifacts (see the update)

The proprietary NVIDIA drivers "disappeared" with my latest update:    The option of "Proprietary drivers for devices" is correctly set under the "Ubuntu Software" tab. I have the graphics-driver PPA (ppa:graphics-drivers/ppa) correctly added to my sources.  Any ideas on how to bring the proprietary drivers back?  PS1: I need them because some of the games I play under wine don't work without them, for whatever reason.  PS2: Also, this feels like it should have a straightforward answer, but I've been looking online for a while without luck.

I have 2 graphics cards (Tesla k10, K40) in my supermicro SuperServer (7047GR-TPRF). I installed Ubuntu Server 14.04, but when I install cuda or Nvidia graphics driver (version 311 or 340), my Ubuntu desktop hangs on login.
