* RedHat/Fedora/Debian/[K]Ubuntu installation information can be found at [http://www.nvnews.net/vbulletin/showthread.php?t=72490]. 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. | |||

==== 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: | |||
<code> | |||
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 | |||
</code> | |||
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 . | |||
