Introduction

By default Ubuntu will use the open source video driver Nouveau for your NVIDIA graphics card. This driver lacks support for 3D acceleration and may not work with the very latest video cards or technologies from NVIDIA.

An alternative to Nouveau are the closed source unified NVIDIA drivers, which are developed by NVIDIA. This driver provides excellent 3D acceleration and video card support.

NVIDIA drivers provided by the Ubuntu repositories

What package one would use depends on the version of Ubuntu one is using, and what graphics card one has installed.

Installation

Usually you will see a notification and/or an icon in the top panel, reminding you that restricted drivers are available.

restricted_drivers.jpg

By clicking the icon you will be taken to a dialog where you can choose which version you want to install, choose the recommended driver.

drivers_dialog.png

If you are using an older version of Ubuntu, or if you aren't notified about additional drivers, you can launch the installation yourself.

  • Go to System -> Administration -> Additional Drivers

  • Once the drivers are downloaded and installed, reboot your computer.

Note: In older version of Ubuntu, Additional Drivers are called Hardware Drivers.

Note: In older version of Ubuntu, newer graphic adapters may not be supported with the repositories provided driver.

Note: In newer version of Ubuntu, older graphic adapters may not be supported with the repositories provided driver.

Removing Nouveau (advanced/expert users)

Nouveau, an open source driver, is installed by default. It's possible to remove it completely, but it is not necessary and therefore not recommended.

If you still desire to remove it, you can do so by entering the following command in a terminal:

sudo apt-get --purge remove xserver-xorg-video-nouveau

Installation without X / from the console

Ubuntu 14.04 and up

The jockey-text command was removed with the release of Ubuntu 14.04. You can now use ubuntu-drivers to get the list of packages for each driver, and then install the packages using apt-get. For example:

sudo ubuntu-drivers devices

/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0

vendor : NVIDIA Corporation modalias : pci:v000010DEd00000DDAsv000017AAsd000021D1bc03sc00i00 model : GF106GLM [Quadro 2000M] driver : xserver-xorg-video-nouveau - distro free builtin driver : nvidia-304-updates - distro non-free driver : nvidia-304 - distro non-free driver : nvidia-331 - distro non-free recommended driver : nvidia-331-updates - distro non-free

sudo apt-get install nvidia-331

Up to Ubuntu 12.04

If you need to change drivers without the use of the X GUI, perhaps because those drivers are not installed, you can with the jockey-text command. For example:

jockey-text --help
jockey-text -l
jockey-text -e xorg:nvidia_current

Troubleshooting

Installation Fails

  • If the restricted driver remains unactivated after attempting to activate it in the Additional Drivers dialog, you may not have the appropriate linux headers installed to compile the driver. Ensure that the linux-headers-XXX and linux-restricted-modules-XXX packages are installed, where XXX matches the version of the kernel you are using.

  • If the activation hangs on download/install dialog, you can install the driver using System -> Administration -> Synaptic Package Manager, make sure you pick the latest driver version recommended by the Additional Drivers tool and all its dependencies. Then go to the Additional Drivers tool and activate the driver you just installed.

Driver Not Active

  • X has not been configured to use the new driver. Open a terminal, run sudo nvidia-xconfig, and restart X (reboot works).

Boot Splash Screen Issues

  • Open up a Terminal and install the Startup-Manager:

    sudo apt-get install startupmanager 
  • Launch the Startup Manager from System -> Administration -> Startup-Manager.

  • In the Boot options tab, change the resolution to something your monitor can handle (1024x768 is usually enough for the boot screen to look nice).

  • Change the color depth to 24 bits and press the Close button, reboot your system.

Can't Save Settings

nvidia-settings can't write to xorg.conf if it hasn't been started with administration privileges. Make sure you start nvidia-settings with the following command:

gksudo nvidia-settings

Some text (for example in menu) is rendered incorrect

With a Ge Force 7600, after installation of the nvidia driver in Ubuntu 14.04 some text and icons are rendered incorrectly, sometimes content is displayed distorted in a triangle instead of a rectanglar window, and X resets intermittently.

Using nouveau the XGA resolution 1024x768 is configured and works. However, manually changing to a different resolution with xrandr, etc. fails.

In order to address these issues, install nvidia-304-updates driver, and change the resolution from auto to something different in nvidia X server settings.

Suspend/Hibernation

If you use an old NVIDIA driver, hibernation & suspend may not work, there is a workaround however.

  • We need to edit xorg.conf, open a terminal and enter the following command:

    gksudo gedit /etc/X11/xorg.conf
  • In the section called Section "Device" add Option "NvAGP" "1", you should end up with something like this:

    Section "Device"
        Identifier     "my id"
        Driver         "my dr"
        VendorName     "my vendor"
        BoardName      "my board name"
        Option         "NvAGP" "1"
    EndSection
  • Blacklist the intel_agp module from being loaded by the kernel. This is done by editing blacklist.conf, open a terminal and type:

    gksudo gedit /etc/modprobe.d/blacklist.conf

    Then add the following line:

    blacklist intel_agp
    Reboot your system.

Onboard Graphics Chipset

Low/Missing Screen Resolutions

Often screen resolutions on offer are far lower than those offered with the open source driver. The NVIDIA binary driver seems to be very weak at reliably probing this information from the monitor and relies on additional information in xorg.conf.

To fix this you can add more resolutions by entering the following in a terminal:

xrandr --addmode S-video ...

Replace the dots with the desired resolution. For further details and potential workarounds see X config resolutions.

Low Resolution Icons and OS Features

If you have problems with low resolution icons, shortcuts and menus placed strangely, and especially desktop size not matching your monitor, this may be due to a bug with multiple monitor setup. If you've previously setup a second monitor and have it plugged in but not turned on, Ubuntu/Xubuntu may be counfounded by this. The simplest method to resolve this is to remove the redundant cable from your machine and reboot. Additionally, install arandr (GUI for xrandr editing) and setup two profiles, one with the secondary monitor and one without. Removal of redundant cable when not in use is nonetheless still recommended. This problem was experienced in Ubuntu and Xubuntu.

Screen Blanks/Monitor Turns Off

Using a laptop with a GeForce Go card, or connecting the sole display via DVI on a dual-head system sometimes results in the screen not receiving a picture. This is caused by the driver outputting video to the VGA port on the graphics card, instead of DVI.

The usual hint that you have this problem is when you hear the startup sound but nothing appears on the screen. If you do not hear any sound, you are more than likely experiencing unrelated problems.

This is a bug about displays on digital outputs being blank when using NVIDIA driver, and can be resolved by editing your /etc/X11/xorg.conf file:

  • Switch to the console by using ctrl+alt+F1, or reboot and select recovery mode from the GRUB menu.

  • Open and edit xorg.conf like this: sudo nano /etc/X11/xorg.conf.

  • Find the line that says: Section "Screen"

  • Insert a new line that says Option "UseDisplayDevice" "DFP".

  • Save the file. If you had to restart into recovery mode, type reboot, otherwise restart your display using sudo /etc/init.d/gdm restart.

Problems with Video Playback

If you have problems with video playback in e.g. mplayer, gxine, or mythtv frontend with a legacy card, it may be due to too high a color depth (e.g. using NT6 Vanta/Vanta LT "nvidia" driver, I experienced flickering vertical bars & blue screen flashing). To fix this, manually edit /etc/X11/xorg.conf and change DefaultDepth to 16.

Creating Application Profiles

nVidia X Server Settings has an application profiles editor much like the Windows counterpart (nVidia Control Pannel) that allows you to set special parameters per-application. For manual text file editing read the Application Profiles ReadMe included in the nVidia for Linux Driver ReadMe. It is quite detailed on where the file locations are, how to enable or disable application profiles completely and what arguments you can use.

For using the nVidia X Server Settings? Follow this basic guide (I'll use Quake 4 as an example)

  • Open up nVidia X Server Settings
  • Go to "Application Profiles"
  • Make sure the check box is selected for "Enable Application Profiles" otherwise the Application Profiles won't work.
  • Click the Add (+) Button for detection rules to "Add a Rule"
  • Make sure for "Rule Pattern" the feature will be used if "Process Name (procname)" is selected
  • For "Matches this string" put in the application name (in this example, quake4)
  • For "Rule Profile" click on "New Profile"
  • In the new popup window, change the profile name to something easy to reference to (in this example I'll name it the same as quake4app)
  • Now, enter any profile settings. You can find the full list in the Application Profiles ReadMe. (in this example, we would select "GLDoom3" from the drop-down menu list to create an SLI Profile for ID Tech 4 Engine-based games)

  • Change the value to whatever you'd like. (in this example, we would set "GLDoom3" Boolean value to "true")
  • Save and close the open windows for the Application profile and the detection rule. (The Add (+) button in the bottom right next to the cancel logo)

We've now created an application profile. One of these days I will list the different process names for ID Tech 4 engine-based games for Linux and their procname's so anyone could easily create working SLI Profiles for these games. I've attempted to use GLDoom3 on other game engines such as the Spark Engine used by Natural Selection 2... sadly it only made the game run at the speed of one GPU, still not enabling the second one to work in SLI outside the ID Tech 4 Engine...

NOTE: The OpenGL Environment Variables are not all listed in the ReadMe. GLDoom3 for example is only discussed in the SLI portion of the driver's ReadMe.

SLI / Multi-GPU on Ubuntu(and Linux in general)

NOTE: This was last tested with nVidia 343.13 drivers... despite these drivers adding support for the GTX Titan Z, a Multi-GPU videocard it still does not support SLI... so the GTX Titan Z is reduced to a single GTX Titan in Linux... same goes for other nVidia Multi-GPU cards such as the GTX 690. sad

For more information, please read SLI & Multi-GPU section of the ReadMe included with nVidia's drivers for Linux.

Current limitations (last tested on 343.22) on nVidia's drivers are as follows:

  • Linux only support SLI & Multi-GPU (Two-GPUs-on-one cards such as the GTX 690) can be enabled, but only via commant promts in the Terminal.

  • Only works on desktop platforms, SLI on mobile GPU's is unsupported.
  • Only ID Tech 4 Engine games are officially supported in SLI by creating an "Application Profile" with GLDoom3 set to "true". Games on ID Tech 4 engine includes Quake 4, Enemy Territory: Quake Wars, Doom 3, Prey and Open Source games on ID Tech 4 include The Dark Mod.
  • GPUs with ECC enabled may not be used in an SLI configuration.
  • SLI on Quadro-based graphics cards always requires a video bridge.
  • TwinView is also not supported with SLI or Multi-GPU. Only one display can be used when SLI or Multi-GPU is enabled, with the exception of Mosaic.

  • If X is configured to use multiple screens and screen 0 has SLI or Multi-GPU enabled, the other screens configured to use the nvidia driver will be disabled. Note that if SLI or Multi-GPU is enabled, the GPUs used by that configuration will be unavailable for single GPU rendering.
  • Alternate Frame Rendering (AFR) and Split Frame Rendering (SFR) are supported in Linux. AFR2 is not supported nor is it planned for Linux.

Alternate Frame Rendering (AFR) is supported. This SLI mode uses each card to render one frame then the next card renders the following. For example, in two-way AFR, GPU1 renders frames 1, 3, 5, etc. and GPU2 renders 2, 4, 6, etc. Outside of the ID Tech 4 engine Alternate Frame Rendering does not work on any card other than the first which causes framerates to drop by 50%. This is a known bug and nVidia are currently working on this issue.

SLI Profiles are NOT included with the drivers unlike the Windows version of the nVidia drivers. They must be manually created for ID Tech 4 Engine-based games. To learn how to make them yourself, please read the Creating Application Profiles section of this wiki page.

Split Frame Rendering (SFR) is also supported. This mode uses the first GPU to render the top half of the screen, and the second GPU to render the bottom half. This mode also does not function correctly outside of ID Tech 4. It will still render the full screen, but only at the speed of a single GPU.

Alternate Frame Rendering mode 2 (AFR2) is NOT supported in Linux. This mode is opposite of Alternate Frame rendering by instead using the last GPU as the primary, and every GPU above it as the next in line. For example, in three-way AFR2? GPU3 renders frames 1, 4, 7, etc. GPU2 renders frames 2, 5, 8, etc. and GPU1 renders frames 3, 6, 9, etc. In Windows, AFR2 is the preferred SLI mode as it tends to yeild higher performance over AFR. My theory is because GPU1 is the primary card for video out, it uses a different GPU for the primary calculations it better balances the work load. I have not seen any documentation as to the specific reason AFR2 performs better.

Despite what was mentioned above, if you wish to try SLI here's how to enable it via the terminal:

  • Open up Terminal.
  • Use the following command of your choice: sli=on (enables SLI) sli=auto (Allows nvidia-xconfig to automatically enable SLI if it detects an SLI-ready setup) sli=afr (enables SLI in AFR mode) sli=sfr (enables SLI in SFR mode).

Terminal commands:

sudo nvidia-xconfig -sli=on
sudo nvidia-xconfig -sli=auto
sudo nvidia-xconfig -sli=afr
sudo nvidia-xconfig -sli=sfr
sudo nvidia-xconfig -sli=off
  • Put in your password
  • Reboot Ubuntu (sudo reboot via terminal or via the GUI)
  • Open up the "nVidia X Server Settings" program
  • Select any GPU in the list, and look for the screen output. If SLI is indeed enabled? It will say "(SLI)" at the end of the detected screen output.

The Only difference is if you have a Multi-GPU (such as the GTX 690) you change the argument of sli to multigpu. Terminal commands:

sudo nvidia-xconfig -multigpu=on
sudo nvidia-xconfig -multigpu=auto
sudo nvidia-xconfig -multigpu=afr
sudo nvidia-xconfig -multigpu=sfr
sudo nvidia-xconfig -multigpu=off

If you have Multi-GPU cards in your system in SLI (such as two GTX 690's with the appropriate SLI bridge) you just have to mix the commands together.Terminal commands:

sudo nvidia-xconfig -sli=on -multigpu=on
sudo nvidia-xconfig -sli=auto -multigpu=auto
sudo nvidia-xconfig -sli=afr -multigpu=afr
sudo nvidia-xconfig -sli=sfr -multigpu=sfr
sudo nvidia-xconfig -sli=off -multigpu=off

SLI Application Profiles for ID Tech 4 Engine Games on Ubuntu (and Linux in general)

The Application profile examples I have below are for:

  • Enemy Territory: Quake Wars (etqw-rthread.x86 & etqw.86)

  • Doom III (doom.x86)
  • Quake IV (quake4smp.x86 & quake4)

  • Prey (prey.x86)
  • The Dark Mod (thedarkmod.x86)

NOTE: This list was compiled with NVIDIA 343 drivers.

Essentially, just enable "GLDoom3" and also "GLThreadedOptimizations". One may also setup an "AlwaysOn" profile setting for "GLThreadedOptimizations" as an example of settings you can always have activated. It's up to you to leave it on or disable it since there's the chance it can affect your OpenGL performance negatively.

To use these application profiles, one way is via the file manager.

  • Open your File Manager.
  • go to your "Home" folder.
  • Tap "CTRL" and "H" to toggle hidden folders and files.
  • Go into the ".nv" folder.
  • Open the file "nvidia-application-profiles-rc" in a text editor (or if it doesn't exist, create the text file).
  • Copy and paste the following into the file and save (the last part with "alwaysapplied" is optional but is recommended for enabling Threaded Optimizations on all OpenGL apps). Some older apps might have compatibility issues but you can always make a custom application profile with the "GLThreadedOptimizations" set to "false"):

    {
        "rules": [
            {
                "pattern": {
                    "feature": "procname",
                    "matches": "prey.x86"

                },
                "profile": "idtech4app"
            },
            {
                "pattern": {
                    "feature": "procname",
                    "matches": "quake4smp.x86"
                },
                "profile": "idtech4app"
            },
            {
                "pattern": {
                    "feature": "procname",
                    "matches": "quake4"
                },
                "profile": "idtech4app"
            },
            {
                "pattern": {

                },
                "profile": "idtech4app"
            },
            {
                "pattern": {
                    "feature": "true",
                    "matches": "alwayson"
                },
                "profile": "alwaysapplies"
            }
        ],
        "profiles": [
            {
                "name": "idtech4app",
                "settings": [
                    {
                        "key": "GLDoom3",
                        "value": true
                    },
                    {
                        "key": "GLThreadedOptimizations",
                        "value": true
                    }
                ]
            },
            {
                "name": "alwaysapplies",
                "settings": [
                    {
                        "key": "GLThreadedOptimizations",
                        "value": true
                    }
                ]
            }
        ]
    }
  • Save and exit.
  • Open up the "nVidia X Server Settings" application.
  • Browse to "Application Profiles".
  • if the "nvidia-application-profiles-rc" didn't properly load the modified configuration? Click the "Reload" button. It looks like a green circle with two circular arrows.

Filing bug reports

NVIDIA driver from the Ubuntu repositories

If one is using a NVIDIA driver package from a supported Ubuntu repository (not downloaded from NVIDIA's website directly), first one would want to file a new report via a terminal:

ubuntu-bug xorg

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

As well, please ensure all of the below are tested and provided:

  • Is this an issue with the latest version downloaded directly from NVIDIA's website?
  • Did this happen with a prior version of the NVIDIA driver?
  • Did this issue happen in a prior release of Ubuntu?

If the issue is not reproducible in the version from NVIDIA's website, then the issue would be a downstream (Ubuntu) issue.

If the issue is reproducible in the version from NVIDIA's website, the next step is to report a bug upstream as per below.

Reporting an upstream bug

If either your downstream bug report is marked Triaged, or you are using the drivers from NVIDIA's website directly, one will want to file a bug report via the NVIDIA Bug Submissions website.

  • Product - This is going to be either GeForce Graphics or Quadro Graphics.

  • Choose OS - Linux/Other Unix
  • Product Name - This may be gathered by executing at a terminal

    lspci -vvnn | grep VGA 
  • Driver Version - This may be gathered by executing at a terminal:

    cat /var/log/dmesg | grep -i nvidia 
  • Question - This is where one would put click-for-click steps on how to reproduce this problem verbatim, as well as your operating system information gathered from a terminal:

    lsb_release -rd
    uname -a 

Next, one would want to contact NVIDIA customer care via Live Chat in order to identify a WORKAROUND, and generate a trackable case number regarding your problem.
