Todays' updates wrecked the resolution

view story

http://forums.fedoraforum.org – I just did the latest updates and now my display is stuck at 800 x 600! How do I get it back to 1280 x 1024 ? After running # nvidia-xconfig and then rebooting. the display is so distorted I can't see anything. and when I do Ctrl-Alt-F1 nothing happens and I can't get to a prompt. How do I get a prompt? This is bad. never had a video problem like this one. (HowTos)
