I am running Zorin OS version 8 Ultimate (based on Ubuntu 13.10 "Linux"). I installed the udates driver from repositories. It is very unclear what Linux driver is actually the most up to date version I need for my system. I have researched this for many hours and tried installing the supposedly needed AMD Catalyst driver needed for Linux for my system.
I seem to have AMD Catalyst driver installed to support an installed Radeon ONE HD5450 graphics card. I can open Catalyst and change the settings. I rebooted a few times after changing settings a few times, and I keep getting one screen staying white. The cursor or pointer for my mouse goes from one screen to another, but one screen has no image, just stays white. I have configured this same driver in Windows7 and had no problems like this in Windows7. Any clues as to what I might be missing here?
