Just installed centos 5.3 with kde. Dual video card - radeon hd 4350. Centos detected that. Tried using system-config-display to change to 1680X1050
. After I click ok, system says display setting is changed. Need to restart. When I restart the system, the screen defaults back to 1280X1024. I tried using init 3, then system-config-display to change but to no avail. Please help...very new to all this.

thanks for all your forth coming replies.
