I recently installed Ubuntu 10.04 onto my desktop, although I cannot seem to get my graphics card working.
When I try to change the resolution it will either display a black rectangle on the upper left hand corner of the screen, and freeze, or it will say that the X Server doesn't support that size resolution. I have tried the default ATI driver that came installed, but that results in the same thing as the FGLRX driver. I have also tried reinstalling several times but with no results. I have tried with both one, and dual display, but I would prefer dual display is that is possible.
Any help appreciated, thanks.
The Graphics card is an ATI [XFX Manufactured]Raedon 5450 1GB
