Nvidia proprietary driver installation

The NVIDIA proprietary driver works much more stable than nouveau, so it's good idea to install it. But this is somehow complicated: First - download it from nvidia.com site. Here "NVIDIA-Linux-x86_64-260.19.44.run" is used. Copy it to dom0. Every next step is done in dom0.

See this page for instruction on how to transfer files to Dom0 (where there is normallyno networking).

WARNING: Nvidia doesn't sign their files. To make it worse, you are forced to download them over a plaintext connection. This means there are virtually dozens of possibilities for somebody to modify this file and provide you with a malicious/backdoored file. You should realize that installing untrusted files into your Dom0 is really a bad idea. Perhaps it might be a better idea to just get a new laptop with integrated Intel GPU? You have been warned, anyway.

Userspace components

Install libraries, Xorg driver, configuration utilities. This can by done by nvidia-installer:

./NVIDIA-Linux-x86_64-260.19.44.run --ui=none --no-x-check --keep --no-nouveau-check

Kernel module

You will need:

  • nvidia kernel module sources (left from previous step)
  • kernel-devel package installed
  • gcc, make, etc

This installation must be done manually, because nvidia-installer refused to install it on Xen kernel. Firstly ensure that kernel-devel package installed all needed files. This should consists of:

  • /usr/src/kernels/2.6.34.1-12.xenlinux.qubes.x86_64
  • /lib/modules/2.6.34.1-12.xenlinux.qubes.x86_64/build symlinked to the above directory
  • /usr/src/kernels/2.6.34.1-12.xenlinux.qubes.x86_64/arch/x64/include/mach-xen should be present (if not - take it from kernel sources)

If it is not true - correct it manually. To build kernel module, enter NVIDIA-Linux-x86_64-260.19.44/kernel directory and execute:

IGNORE_XEN_PRESENCE=1 CC="gcc -DNV_VMAP_4_PRESENT -DNV_SIGNAL_STRUCT_RLIM" make -f Makefile.kbuild
mv /lib/modules/2.6.34.1-12.xenlinux.qubes.x86_64/kernel/drivers/video/nvidia.ko /lib/modules/2.6.34.1-12.xenlinux.qubes.x86_64/extra/

Ignore error while inserting nvidia.ko (at the end of make phase). Now you should disable nouveau:

cat /etc/modprobe.d/nouveau-disable.conf
# blacklist isn't enough...
install nouveau /bin/true

Configure Xorg

After all, you should configure Xorg to use nvidia driver. You can use nvidia-xconfig or do it manually:

X -configure
mv /root/xorg.conf.new /etc/X11/xorg.conf
# replace Driver in Device section by "nvidia"
