I have an Ati radeon x1550, and connected to that a DVI monitor (and another to the VGA, but this bug is present also when only the DVI monitor is connected) This bug appears in every distribution and kernel I tried, the last one is fedora 16, but I tried debian 6 too and Archlinux with the latest kernel. Description of problem: DVI screen, if on standard resolution (1680x1050) blinks from the tty to the Gnome dekstop, and especially when something like Firefox is made fullscreen: I recorded a video to explain this better: https://www.youtube.com/watch?v=8Tcjb6p0Yi4
