video problems on dual-link monitors upon reboot on F12


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?

If the airwaves belong to the public why does the public only get 3
non-overlapping WIFI channels?
