Summary: Flicker after waking from DPMS sleep Product: DRI Version: XOrg CVS Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: minor Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: curaga@operamail.com

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).

--- Comment #3 from Simon Strandman simon.strandman@gmail.com 2011-10-04 01:05:19 PDT --- I have this problem too on similar E350-based hardware.
Sometimes I get this flicker, sometimes the screen is garbled (bug #36513). When I get a garbled screen the flicker usually persists even after a reboot. (Though this never happens in windows so I don't think it's a hardware issue.)

--- Comment #4 from Marc Deslauriers marc.deslauriers@canonical.com 2011-10-15 20:03:41 PDT --- I am getting this on a C-50 based Acer Aspire One 522. I can reliably reproduce the issue with:
xset dpms force off; sleep 10; xset dpms force on
