It sounds a bit like your tab key is getting stuck, or something is causing your computer to think the tab key is held down. (And possibly another key like alt.) The flickering you describe sounds like the fast shift of focus from one menu entry to the next and back around. On your other machine: try holding down (or tapping very quickly) tab and another key (such as as alt, shift, or ctrl) and see if the behavior is similar. This doesn't sound like an actual video problem to me, mostly because of what you saw in the terminal. --Rogan > > Finally I tried other programs and discovered that the flickering was > happening with all of them. > > I rebooted the computer and the flickering started as soon as the GUI > came up.
