How to install Nvidia Driver with pacman
Info from Package Maintainer tpowa
The package is for those people who run a stock arch kernel! I only test with kernel 2.6 and xorg.
NOTE by someone else: we didn't forget people using the -beyond kernel, check next paragraph
Multiple kernel users: You need to install nvidia package for each extra!
You have to use extra repository, enable it for pacman. Leave X-Server, else pacman cannot finish installation and it will not work! As root, run:
pacman -Sy nvidia (for newer cards) pacman -Sy nvidia-96xx or pacman -Sy nvidia-71xx (for older cards)
For -beyond users:
pacman -Sy nvidia-beyond pacman -Sy nvidia-96xx-beyond or pacman -Sy nvidia-71xx-beyond (for older cards)
If you use the -ck, -suspend2 or -mm kernels, adjust the above command appropriately.
README from nvidia for details on which card is supported by which driver.
/etc/X11/XF86Config or your
/etc/X11/xorg.conf config file:
Disable in modules section:
Add to modules section:
Make sure you DON'T have a line
in the Module section since recent versions of xorg-server does not include the type1 font module (completely replaced by freetype).
Section DRI completely:
#Section "DRI" # Mode 0666 #EndSection
Driver "nv" or
Driver "vesa" to
If it exists disable
Chipset option (only needed for nv driver).
This was for basic setup, if you need more tweaking options
have a look at
You can also run:
Enabling Composite in Xorg
Refer to the Composite wiki for detailed instructions.
/etc/rc.conf MODULES section (not needed anymore if you run xorg and udev).
Needed for nvidia-71xx and kernel >=2.6.13!
Problems that might occur
Please remove your old /usr/X11R6 dir it can cause trouble during installation. Also make sure you've installed
pkgconfig. The NVIDIA installer uses pkgconfig to determine where modular Xorg components are installed.
If you experience slow 3D Performance have a look at
Perhaps they are wrong linked to mesa or something else.
Try reinstalling with
pacman -S nvidia.
When you get this message when you try to start an openGL application (for example enemy-territory, or glxgears):
Error: Could not open /dev/nvidiactl because the permissions are too restrictive. Please see the
FREQUENTLY ASKED QUESTIONSsection of
/usr/share/doc/NVIDIA_GLX-1.0/READMEfor steps to correct.
Add yourself to the
video group using
gpasswd -a yourusername video (don't forget to log out and back in, or type: source /etc/profile).
You must compile the module with the compiler that was used for the kernel
else it may fail.
pacman -S nvidia should do it, if not wait for a new kernel release and stay with old kernel and gcc.
Kernel update: Kernel updates will require reinstalling the driver. A workaround is available.
Driver Config Tool
The new config tool for the nvidia-drivers is included called 'nvidia-settings'
You don't have to use it it's only a add-on!
For more information about the use, have a look at the following file:
Please install gtk2 with "pacman -S gtk2" in order to use this tool.
If you experience problems like crashing the X-Server while running the tool
you have to delete your
.nvidia-settings-rc file in your home directory.
Nvidia-Settings Autostart: You might like to apply the settings chosen using nvidia-settings at startup, firstly run nvidia-settings at least once in order for settings to be restored. The settings file is stored in ~/.nvidia-settings-rc. Then add the following to the auto-startup method of your DE:
If you experience crashes, try to disable
RenderAccel "True" option.
If you have nvidia installer complaining about different versions of gcc between the current one and the one used for compiling the kernel then see on how to install the traditional way but remember to
If you have comments on the package please post it here: http://bbs.archlinux.org/viewtopic.php?t=10692 If you have a problem with the drivers have a look at the nvidia forum: http://www.nvnews.net/vbulletin/forumdisplay.php?s=&forumid=14 For a Changelog please look here: http://www.nvidia.com/object/linux_display_ia32_1.0-8762.html
Note: please don't change the above part without notifying me.
Bad performance after installing new nvidia-driver
If you experience very slow fps rate in compare with older driver first check if You have Direct Rendering turned on. You can do it by:
glxinfo | grep direct
If You get: direct rendering: No then that's your problem. Next check if You have the same versions of glx for the client and server by this:
glxinfo | egrep "glx (vendor|version)"
And if you see different vendors or versions for the client and server run this:
ln -fs /usr/lib/libGL.so.$VER /usr/X11R6/lib/libGL.so ln -fs /usr/lib/libGL.so.$VER /usr/X11R6/lib/libGL.so.1 ln -fs /usr/lib/libGL.so.$VER /usr/lib/libGL.so.1.2
Where $VER is the version of nvidia package, that you're using. You can check it by
That's all. Now restart your Xserver and you should have normal acceleration.
How to install NVIDIA Driver the traditional way
WARNING This will give you a whole new series of problems to deal with, because of libgl being provided by the pacman package, you will have to create an empty dummy libgvl package, and you'll still need nvidia-utils for Mesa OpenGL library, otherwise packages you install will depend on mesa also. Read more here: http://bbs.archlinux.org/viewtopic.php?pid=286530
- Download the latest NVIDIA driver from: http://www.nvidia.com/object/linux.html
File name will look something like this:
The Kernel Steps (the following 4 steps) can be left out if you use at least kernel 2.6.5 because the needed Includes are now in the Kernel package
- Download the kernel source for the kernel version you are using
uname -r will give you kernel version
- Move the current incomplete kernel source tree to 2.x.x.old:
mv /usr/src/2.x.x /usr/src/2.x.x.old
- Uncompress and unpack your source code in
mv /path/to/linux-2.x.x.tar.bz2 /usr/src cd /usr/src tar --bzip2 -xvf linux-2.x.x.tar.bz2
- Copy the old include directory and
.configfile into new source tree:
cp -rp linux-2.x.x.old/include/ linux-2.x.x/include/ cp linux-2.x.x.old/.config linux-2.x.x/.config
- Go to a non-graphical session
- Use Control-Alt-F5 (or whatever F key you want)
- Login as root
- Go to runlevel 3
- Run NVIDIA installer
You will be asked to accept their license, then hit OK a couple times on informational screens, the driver will then be built and installed
- Edit XFree86Config file
- Use the editor of choice to open
/etc/X11/XFree86Configand go to the
- Change your driver from current (probably
- Uncomment the glx load line
- Comment or delete the Chipset line if exists
- Use the editor of choice to open
- Edit modules loaded on boot
nvidiato modules section
MODULES=(... some modules ... nvidia)
- Reboot the machine and enjoy 3D acceleration...and a tainted kernel :)
Tweaking NVIDIA drivers
/etc/X11/XFree86Config with your editor of choice and try the following options to improve performance.
Not all options may work for your system, try them carefully and always backup your configuration file.
Disable NVIDIA Graphics Logo on startup
Device section add the
Option "NoLogo" "True"
Enable hardware acceleration
Device section add the
Option "RenderAccel" "True"
NOTE: The RenderAccel is enabled by default since drivers version 9746.
Override monitor detection
"ConnectedMonitor" Option under
Device section allows to override the monitor detection when X server starts. This may save a bunch of seconds at start up. The available options are:
"CRT" (cathode ray tube),
"DFP" (digital flat panel), or
The following statement force NVIDIA drivers to use DFP monitors.
Option "ConnectedMonitor" "DFP"
NOTE: use "CRT" for all analog 15 pin VGA connections (even if you have a flat panel). "DFP" is intended for DVI digital connections only!
Enable the use of triple buffering by adding under
Device section the
Option "TripleBuffer" "True"
Use this option if your GPU has plenty of ram (128mb and more) and combined with "Sync to VBlank". You may enable sync to vblank in nvidia-settings.
This option is used to enable the server's support for backing store, a mechanism by which pixel data for occluded window regions is remembered by the server thereby alleviating the need to send expose events to X clients when the data needs to be redisplayed. BackingStore is not bounded to NVIDIA drivers but to X server itself. ATI users would benefit of this option as well.
Under Device section add:
Option "BackingStore" "True"
Use OS-level events
Taken from NVIDIA drivers README file: "Use OS-level events to efficiently notify X when a client has performed direct rendering to a window that needs to be composited." Whatever it means, it may help improve performance. This option is currently incompatible with SLI and Multi-GPU modes.
Device section add:
Option "DamageEvents" "True"
This option is enabled by default in newer driver.
Enable power saving
... For a greener planet (not strictly related to NVIDIA drivers). Under
Monitor section add:
Option "DPMS" "True"
Using TV-out on your NVIDIA card
Good article on the subject can be found from:
Why is the refresh rate not reported correctly by utilities that use the XRandR X extension (e.g., the GNOME "Screen Resolution Preferences" panel, `xrandr -q`, etc)?
The XRandR X extension is not presently aware of multiple display devices on a single X screen; it only sees the MetaMode bounding box, which may contain one or more actual modes. This means that if multiple MetaModes have the same bounding box, XRandR will not be able to distinguish between them.
In order to support DynamicTwinView, the NVIDIA X driver must make each MetaMode appear to be unique to XRandR. Presently, the NVIDIA X driver accomplishes this by using the refresh rate as a unique identifier.
You can use `nvidia-settings -q RefreshRate` to query the actual refresh rate on each display device.
The XRandR extension is currently being redesigned by the X.Org community, so the refresh rate workaround may be removed at some point in the future.
This workaround can also be disabled by setting the "DynamicTwinView" X configuration option to FALSE, which will disable NV-CONTROL support for manipulating MetaModes, but will cause the XRandR and XF86VidMode visible refresh rate to be accurate.
How to install NVIDIA Driver with custom kernel
It's an advantage to know how the ABS system works by reading some of the other wiki pages about it, first:
We will create our own pacman package quickly by using ABS, which will compile the module for the currently running kernel:
Make a temporary directory for creating our new package:
mkdir -p /var/abs/local/
Make a copy of the nvidia package directory:
cp -r /var/abs/extra/x11/nvidia/ /var/abs/local/
Go into our temporary nvidia directory:
We need to edit the two files nvidia.install and the PKGBUILD file, so they contain the right kernel version variables, so we don't have to move it from the stock kernel /lib/modules/2.6.xx-ARCH directory.
You can get your kernel version and local version name if you type:
- In nvidia.install replace the KERNEL_VERSION="2.6.xx-ARCH" variable with your kernel version, such as KERNEL_VERSION="126.96.36.199" or KERNEL_VERSION"188.8.131.52-custom" depending on what your kernels version is and local version text/number. Do this for all instances of the version number within this file.
- In PKGBUILD change the _kernver='2.6.xx-ARCH' variable to match your kernel version again, like above.
- If you have more than one kernel coexisting in parallel with another, (such as a custom kernel alongside the default -ARCH kernel) change the "pkgname=nvidia" variable in the PKGBUILD to a unique identifier, such as nvidia-2622 or nvidia-custom. This will allow both kernels to use the nvidia module, since the custom nvidia module has a different package name and will not overwrite the original.
makepkg -i -c
.. Now it will automatically build the NVIDIA module for your custom kernel and clean up the leftover files from creating the package. Enjoy!
