I've also encountered this bug on Ubuntu Karmic 9.10 with nvidia-glx-96
96.43.13-0ubuntu6.
So far I have tried to enable nvidia driver through jockey-gtk and Xserver goes
into failsafe mode on startup.
I chose the troubleshooting option in notification dialog on startup and
backed up xorg.conf and log files.
last lines from :0.log may be related to fact that nvidias' driver is trying to
initialise GART and fails :
-----

Maybe this error happens because gpu doesn't support GART?
I checked man nvidia-xconfig whisch says:
--nvagp=NVAGP, --no-nvagp
Set the NvAGP X config option value. Possible values are 0
(no AGP), 1 (NVIDIA's AGP), 2 (AGPGART), 3 (try AGPGART, then try
NVIDIA's AGP); these values can also be specified as 'none',
'nvagp', 'agpgart', or 'any'.
Further I ran:
sudo nvidia-xconfig --nvagp=1 to use only nvidiaagp
And now I'm going to restart and see if it helps.
