nvidia 8800 gtx under ubuntu feisty

if you should ever have to use an nvidia 8800 gtx under ubuntu feisty:

download the latest nvidia linux driver and install it like this (don’t download the beta drivers). that does not work after rebooting anymore.

open /etc/modprobe.d/lrm-video and comment out some lines:
## Make nvidia/nvidia_legacy and fglrx use /sbin/lrm-video to load
#install fglrx /sbin/lrm-video fglrx $CMDLINE_OPTS
install nvidia /sbin/lrm-video nvidia $CMDLINE_OPTS
#install nvidia_legacy /sbin/lrm-video nvidia_legacy $CMDLINE_OPTS
#install nvidia_new /sbin/lrm-video nvidia_new $CMDLINE_OPTS

open /etc/default/linux-restricted-modules-common and disable the modules fglrx, nvidia_legacy, nvidia_new

add the following lines to /etc/X11/xorg.conf
Section “Extensions”
Option “Composite” “Enable”
