Why not have a little GNOME launcher that does a sed to /etc/X11/xorg.conf (you can even use RBAC) to change the driver from nvdia to vesa (or probably less effort drops in an xorg.conf that specifiies vesa or removes it which defaults to nvidia). Restart your X session with a ctl-alt-bksp and you are done. No need to boot to a different configuration to do this. Bob
