Distorted colors and patterns on a laptop
I had this problem before but can't find the fix for it.
Reloaded Ubuntu 13.04 on a Toshiba Satellite L355D with an ATI RS690 graphics card detected. Both the shutdown dialogue box and search screens have a distorted Green color pattern. The background theme is perfect. The fix I used last time was to enter some code from a terminal window... but don't remember where I found it...
