First... sorry about mailing you and the list at the same time Anders... I sometimes forget to clean up the To:/Cc: fields before I click send....
After the YOU update, and a reboot (which took me about a week before I rebooted) the graphics were hosed. I have a dual monitor setup using nVidia's Twinview options. It used to work perfectly - I had full 3D accelleration on both montiors etc. Now, I don't have any 3D accel at all, and only one monitor is working.. the second monitor is being driven out of range.
Did you try reinstalling the nvidia driver? Updating either X or the kernel with YOU will uninstall it
I did some more tinkering... I ended up having to maually run the nvidia installer from /usr/share/doc/nvidia plus roll back all my xorg to the previous version. Now I'm upgrading one package set at a time to try and find the culprit... if I can nail it down to one I'll re-post ot the list here.... C
