Kubuntu Video Problems

[millenium_dare]

Hi Guys,

I just got the Kubuntu distro. and when I installed it everything worked except that I wanted to change the resolution to 1280 x 1024. My problem is that when I go into the Display properties and change the video driver, I cant get back into the OS when I restart the comp. or X-Server. If I restart x-server and try to log in, it gives me a black screen. When I restart the comp. it loads everything and then gives me a second loading screen, but nothing loads. HELP PLEASE.

Thanks
