Trouble installing ATI Drivers in Ubuntu

[MDE]

I installed Ubuntu (Edgy) on a spare hard drive to mess around with and immediately ran into trouble. My screen resolution is locked at 1600x1200 60Hz (it says 86Hz in the Screen Resolution drop box). So I tried installing video drivers with guides from here (black screen on boot up after Ubuntu startup splash screen) and here (just didn't work) with no luck. Any suggestions for a relative Linux newbie?

EDIT: This is with the AMD64 version of Ubuntu and a Radeon X1900 XT.

Have you asked on the Ubuntu Forums?

Did your original install display properly but just not allow the resolution to be changed?

Yeah, it showed the other resolutions but just went right back to 1600x1200.

Ah, I've seen a fresh install locked at just one resolution (only one resolution available) and reconfiguring xorg (dpkg-reconfigure xserver-xorg) would solve it. You could backup your xorg.conf and give that a try.

Edit your xorg.conf and delete the metamodes that does not function...
