Summary: Display flickers when setting power_profile Product: DRI Version: unspecified Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: egore@gmx.de
When calling something like
echo "low" > /sys/class/drm/card0/device/power_profile
my display flickers a single time. This is okay-ish, but on Microsoft Windows the clock changes do not cause such a flicker. There has to be some kind of trick to achieve that and it would be great if this would work an Linux, too.
Tested on vanilla kernel 2.6.39 with libdrm 2.4.26 and xf86-video-ati 6.14.2.

--- Comment #2 from Erdem U. Altinyurt spamjunkeater@gmail.com 2012-05-15 17:25:36 PDT --- I have this flickering issue too on my HD8650. But not only moving to high to low profile. It flickers low to high profile too! This doesn't let us use "dynpm"...
Using Kernel 3.3.5 with mesa/radeon/drm trunk.
