My E-350 laptop screen flickers for ~5 minutes every time after waking from
DPMS. The flicker persists through VT switches and changing the power profile
to high.

After the wait it stabilizes and picture is good again.

It looks similar to a CRT on 60Hz, but xrandr is confident the mode is right
for the lcd (60hz, not something lower).
