graphics cards and drivers
- NVidia (proprietary driver download for Linux at ; "Latest cards" list at , "Legacy cards" list at ).
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
If everything is ok with the driver you get the following output from "glxinfo|head":
