I am new to Linux but I love it so far. I installed Ubuntu 12.10 (32 bit) on my laptop It runs fine until it I try to run to many things at once. If I ever try to install anything, or I have two many taps up on Firefox Then my screen starts to flicker really bad and if it gets to bad then the screen goes half black and the other half gets all scrambled. Even if I kill all the software I have been using, the flickering does not go away until I reboot. I read the thread named "Screen Flickering" So I figured I would provide the information requested on that thread.
