Just a follow up on this. I disabled Nouveau and installed the latest
NVIDIA drivers but it's acting a bit wonky. Here's what I did:
- created /*/etc/modprobe.d/disable-nouveau.conf*/ which contains the
blacklist nouveau options nouveau modeset=0
- Then I modified /*/etc/grub.conf */so that the Kernel vmlinuz line
- Then I rebooted and manually installed the NVIDIA drivers as I usually
do. The installer ran normally and modified the /etc/X11/xorg.conf as
- Brought the system up to telinit 5 and graphics work normally using
NVIDIA. Acceleration is active and looks good.
Now here's the wonky part. I log off to get back to the login screen
and the graphics wig out. Everything gets choppy and distorted. I
tried ctrl-alt-f2 and was barely able to make out the words printed on
the screen. I tried going down to telinit 3 and then back up to telinit
5 but that did nothing. I had to reboot the system which resulted in
graphics running normally again. The problem repeats when I log in and
then log off. Everything is cool until I log off graphically at the

GIGABYTE GV-N440D3-1GI GeForce GT 440 Video Card
GIGABYTE GA-Z68XP-UD3 motherboard
Intel Core i7-2600K Sandy Bridge 3.4GHz processor
ASUS VE276Q 27" monitor

a setting and the system is trying to load something Nouveau related and
Any ideas would be appreciated....
