I do, and i am. So how on earth do I get rid of it?

I'm trying to install the NVIDIA 177.82 driver for my Geforce 7600GT card in Ubuntu 8.04
Every time I try it stops with the message:
The document referred to in the message tells me to change the default runlevel in /etc/inittab to 1 or 2 to install it, then change it back to 3 or 5 or whatever to get my desktop back.
Unfortunately, Ubuntu 8.04 doesn't appear to have a file called inittab and if I create one in the /etc directory containing id:2:initdefault: it appears to be completely ignored on restart.

So, how can I get out of X, kill it, and then get back in once I have installed the drivers?

Thanks

To stop the X server in Ubuntu you can try
from a terminal. Then switch to a virtual console, e.g. press Alt-Ctrl-F1, login and launch the Nvidia installer from there. When you've finished, do
logout from the console, switch to the X screen (Alt-Ctrl-F7) and the trick is done!

goto a tty (ctrl-alt-f1)
login as root
kill gdm or kdm (killall gdm or killall kdm)
then do your thing
restart X (gdm or kdm)

That did the trick - thanks.
