[ snip: returning to the nvidia 1.0.8774 packages makes X work again ]
There seems to be a problem with the 8776 nvidia kernel module. The
first thing to check is if "modprobe nvidia" gives you any error
messages for the new module. Furthermore, it is important that the
necessary device nodes are created when the module is loaded:
$ ls -l /dev/{nvidia,fb,agp}*
crw-rw---- 1 root video 10, 175 2006-10-30 10:04 /dev/agpgart
crw-rw---- 1 root video 29, 0 2006-10-30 10:04 /dev/fb0
crw-rw-rw- 1 root root 195, 0 2006-10-30 09:07 /dev/nvidia0
crw-rw-rw- 1 root root 195, 255 2006-10-30 09:07 /dev/nvidiactl
Also make sure that the right version of the nvidia X driver was loaded
by looking for lines like these in the Xorg log:
(II) NVIDIA X Driver 1.0-8776 Mon Oct 16 21:58:46 PDT 2006
(II) NVIDIA Unified Driver for all Supported NVIDIA GPUs
(--) Chipset NVIDIA GPU found
Finally, it might help to reboot after installing the new packages if
the problem is due to conflicts in the assignment of interrupts.
