Yesterday, my screen starting flickering like mad, changing colours and failing, 'til the point my netbook in unusable. I'm running Kubuntu 11.04 amd64, and had just installed the last 230 updates KPackageKit offered (I hadn't had internet access for a while).
The netbook started up normally after reboot, and then after a while, this began to happen. After force shutting it down, I tried to roll back to previous kernel, but the problem persists during boot screen as well. I downloaded 11.11 and managed to boot from my USB drive, but still, the screen does the same thing.
This is definitely a hardware problem, isn't it? Bad contact between screen and graphics adapter? Graphics adapter itself? What do you guys think?
Thanks in advace!
