Since installing Ubuntu on my laptop, my screen keeps flashing randomly, usually several times each minute. It happens so quickly that I can't tell what color it flashes, only that is flashing (I think it's white, but I don't know for sure because it only shows for a split second). Mostly, it appears to affect only part of the screen.
It's just a (major) annoyance, but I'm wondering if there's a fix for this or if it's an indicator of a deeper issue. I was unable to reproduce this issue booting to Windows 7 on the same laptop or using Ubuntu (installed from the same disk) on my other box.
