Trouble with display resolution when installing ATI Firepro 2460
I'm currently trying to install a new graphic board, ATI FirePro 2460 on a desktop computer. I'm using Red Hat. After some minor trouble, I manage to install the board and now it works partly. I'm only getting a resolution of 640 x 480. I've tried to use the aticonfigure but it didn't work. I have also tried the ATI graphical tool, but since the total resolution is only 640 x 480, most of the ATI window is unreachable.
(The max display size is 640x480, while all the utility windows is large and therefore only parts of the utility windows is inside the max display area).
