I use the nvidia-* packages version 1.0.8776-1 on my Sid system with a
custom kernel (compiled from linux-source-2.6.18 version 2.6.18-3) and I
do not have any problem.
Maybe the old nvidia kernel module was not properly unloaded in your
case and that gave problems when you started X again due to version
mismatch.
I would try this:
Shut down X; install the new nvidia-kernel-source package again.
# module-assiant auto-install nvidia
Make sure the new version of the module is loaded:
$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA Linux x86 Kernel Module 1.0-8776 Mon Oct 16 21:56:04 PDT
2006
GCC version: gcc version 4.1.2 20061020 (prerelease) (Debian 4.1.1-17)
If you still have the old module loaded try "modprobe -r nvidia"
followed by "modprobe nvidia". If this fails to load the new module then
check the version string of the nvidia.ko file in /lib/modules:
$ strings /lib/modules/$(uname -r)/nvidia/nvidia.ko | grep "nvidia id"
nvidia id: NVIDIA Linux x86 Kernel Module 1.0-8776 Mon Oct 16 21:56:04 PDT
2006
Once you have made sure that the 1.0-8776 module can be loaded, install
the new nvidia-glx package and verify that the libglx.so symlink points
to the right file:
$ file /usr/lib/xorg/modules/extensions/libglx.so
/usr/lib/xorg/modules/extensions/libglx.so: symbolic link to
`libglx.so.1.0.8776'
Also check the version of nvidia_drv.o:
$ strings /usr/lib/xorg/modules/drivers/nvidia_drv.o | grep "nvidia id"
nvidia id: NVIDIA X Driver 1.0-8776 Mon Oct 16 21:58:46 PDT 2006
If all versions are consistent then X should start again. If it does not
then run
$ egrep '^\((EE|WW)\)' /var/log/Xorg.0.log
and check the output for clues.
