For about a year I've been seeing this problem pop up occasionally under F12 (and F11 before that). When the kernel or Xorg changes there is a high probability of a reboot leaving the dual-link monitor in a slightly messed up state. The video looks like there are several superimposed frames with perhaps a half inch registration problems (at 100dpi). Doing a shutdown and restarting with the power button clears up the issue. I guess some state isn't being correctly re-initialized by a reboot, but once cleared by actually powering down, will work. Is anyone else with a dual link monitor seeing this? Are there any kernel or xorg switches to clear more framebuffer state on startup? -wolfgang -- Wolfgang S.
