Re: 8600 fails to load properly in Ubuntu 8.04
1. Run the uninstall from the driver version that you installed with. You should do this from a console window same as 3 below.
2. Make sure that you have removed all traces of the nvidia driver packages that are the default with Ubuntu. There are many posts on this both here and the ubuntu forums.
3. Go to a console window [Ctrl-Alt-F1], login and to stop X, use:
sudo /etc/init.d/gdm stop
4. Install the driver as per the instructions. Let the nvidia driver install write a new xorg.conf file.
PS: nvidia is the nvidia driver. There is no reason to go to init1. Personally I usually go to init 3 out of habit, but the runlevels for ubuntu have no relation to what used to be a psuedo-standard.
