Hello everyone. I am in desperate need of help, my screen keeps displaying random colours and failing after a several minutes of logging on, but the system does not crash at all. Also, I enjoy computer games very much and when I run games,the graphics in the games starts failing. I think this is to do with the graphics driver that ubuntu has when was installed not being compatable with my graphics card, I couldn't find a graphics driver for my graphics card that works on ubuntu. My computer is a Toshiba Satellite L300D. A lot of people on the internet say that toshiba laptops are not compatable with linux, it might be something to do with that as well. My graphics card is either a ATI Radeon X1250 or a ATI Radeon X1200.
