I recently got an software upgrade notice that included a new kernel and NVidia drivers, among other things. I have a video card with a NVidia GeForce 8500 GT chip set. I had been using restricted drivers and things had been working well. Now I get 640X480 only and apparently I am no longer using any proprietary drivers. Does anybody have any suggestions on
1) how to fix the video system? Without writing my own drivers?
2) how to ignore upgrades without being pestered by the system that new upgrades are available?
Thanks,
Hugh

The update apparently trashed the xorg.conf file. "sudo dpkg-reconfigure -phigh xserver-xorg" seems to fix it.

It seems that while I was flailing around in 640x480 mode, I deleted part of my control panel. Does anybody know how to get back to the default panel? I tried to add a main menu, but that just puts up an icon whose drop down contains Places, System, Applications, etc. I used to have those in individual tabs on the main panel. I'd like to get the default look back, as I got sort of use to it. It's no disaster if I can't.

Thanks for the pointers, Scott.
