Latest 11 update changed my resolution.

[Mike Adolf]

Greetings
I just did the latest Fedora 11 update to kernel 2.6.29.6-213.fc11.185.
My screen resolution use to be 1680 x 1050 now it is 1280 x 1024 and
everything looks squashed. Preferences/Display won't let me change it.
The drop down doesn't list the 1680 x 1050. It also indicated that my
monitor is now unknown. I have a NVIDIA GeForce 7900 GS.

How do I fix this?

Mike
