I have a Samsung R540 and yesterday installed Ubuntu alongside Windows. This is a new computer, and I did the install from a disk. Everything seemed fine yesterday aside from scroll not working on the touchpad, but I've found some work arounds and while annoying, I'm not overly concerned. However, a few minutes ago, the brightness just started flickering. At first I was afraid it was a video card problem, but then the brightness setting popped up and it was going wild - jumping all over the place. The laptop was frozen while it did this. It stopped and I was able to restart, but it started doing it a few minutes later. Has anyone else experienced this?
Thanks.
