This has never failed me (on RHEL and openSuSE):
1) Switch to a console (CTRL+ALT+F2)
2) Log in as root
3) switch to runlevel 3 (this will kill any X-server)
$> init 3
4) install the device driver
5) switch back to runlevel 5 (automatically restarts X-server)
$> init 5
Ubuntu might do things differently.
All the best,
Andy
