graphics cards and drivers
- 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.
The proprietary driver works well but it needs a bit of care. 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 automatically 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 . If everything is ok with the driver you get the following output from "glxinfo|head":
