graphics cards and drivers

NVidia

  • NVidia - proprietary driver download for Linux at [1]
  • "Latest cards" list at [2]
  • "Legacy cards" list at [3]
  • RedHat/Fedora/Debian/[K]Ubuntu installation information can be found at [4]. In particular, for RedHat/Fedora one needs to install the kernel-devel RPM package. Other than this, the information in that posting seems a bit overkill - the NVidia driver usually works very well without any SElinux jiggling.

checking the integrity of the NVidia driver

If everything is ok with the driver, you get the following output from "glxinfo|head":

name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
server glx extensions:
   GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig,
   GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control,
   GLX_EXT_texture_from_pixmap, GLX_ARB_multisample, GLX_NV_float_buffer
client glx vendor string: NVIDIA Corporation

maintaining the NVidia driver

The proprietary driver works well but it needs a bit of care. More to the point: parts of it need to be re-installed after kernel updates and updates of xorg-x11-* (both of which happen regularly). On RedHat systems that are regularly booted, the following lines in /etc/rc.local result in the necessary parts of the driver being re-installed automagically after booting:

if [ ! -h /usr/lib/xorg/modules/extensions/libglx.so ]; then
  echo "re-installing NVIDIA driver. This takes some time. Ignore any warnings."
  /root/NVIDIA.run --no-network -s -n
fi

if [ ! -e /lib/modules/`uname -r`/kernel/drivers/video/nvidia.ko ]; then
  echo "installing NVIDIA kernel module. This takes some time. Ignore any warnings."
  /root/NVIDIA.run --no-network -s -K -n
fi

This requires that you first "chmod +x" the driver package (e.g. NVIDIA-Linux-x86-169.04-pkg1.run) downloaded from the NVidia site, and then establish a symbolic link from it, to /root/NVIDIA.run .

ATI

ATI now belongs to AMD. Download the proprietary driver from http://ati.amd.com .
