nvidia driver error - xorg doesn't start

[antonio giulio <antongiulio05@gmail.com>]

Hi,

I have in /etc/modules 'nvidia' and my kernel is 2.6.12.
After last update I cannot enter in kdm more. I got error for 'screens
not found etc.', but nvidia is present in '/etc/modules'. If I launch
'modprobe nvidia', kdm starts.
However when I try to enter in KDE, it returns to kdm login page again.
I have last version from repository unstable of udev.
Could be it same problem of thread:

???
my nvidia-version is 7174

Thanks,
Giulio
