A couple questions: display space and driver question 11.1

During install I could see the whole monitor space, now I have a black stripe of 1 cm on the right. I installed the ATI drivers, seems to have made it worse than default as I can’t adjust it out through monitor with horizontal adj. Resolution is reported as 1280 x 1024 but it is not showing that.KDE gui, 4.1. 17 inch analog LCD.

Also, this motherboard has a set of linux drivers, do I need to install those for all functions to work? I’m most concerned about energy consumption, temp monitoring. The cpu seems to clock down to 1ghz? Seems really low since its 2.5ghz.

System is AMD 4850e, Asus mb with AMD 3200 onboard graphics, 64 GB SSD. Thanks for any help.
