Public bug reported:

After installing Oneiric beta 2 on a Acer Aspire One 522 with an AMD
C-50 chipset, when the screen is shut off with dpms and comes back on,
the LCD flickers. The longer the screen is turned off, the more severe
the flickering is when it is turned back on. When the flickering occurs,
waiting a couple of minutes makes the flicker grow progressively better
until it is gone completely.

How to reproduce:
xset dpms force off; sleep 10; xset dpms force on
