Ubuntu 9.10 - Display distorted on netbook

Posted Tue, 2009-11-24 21:49 by cohiba

New to Ubuntu, but after installation of Ubuntu 9.10 my screen on the netbook (VIA 1024x600) does not work. It gives a distorted signal, unreadable. When I connect an external screen the display shows a perfect picture. I noticed I cannot select a resolution of 1024x600 in the display settings. Could this be the problem?
