Oh, I forgot to mention that changing the radeon "power_profile" fixes the problem, ie doing: echo low > /sys/class/drm/card0/device/power_profile fixes the problem, and there's no flickering anymore! Did this work in the past and if so, when? Please attach your xorg log and dmesg output. Created attachment 52313 [details]

Hmm.. I'm pretty sure I didn't see flickering in Fedora 14 (Linux 2.6.35). Flickering starts already before Xorg is started. I just tried Fedora 16 final TC1 (Test Compose 1) which has Linux kernel 3.1.0-0.rc9.git0.0.fc16.x86_64. The same heavy flickering/distortion problem happens there. I'll attach new dmesg for 3.1.0-0.rc9.git0.0.fc16.x86_64 and Xorg.0.log. The flickering seems to happen on these conditions: - Laptop starts with LID closed, so BIOS has internal LVDS disabled. The laptop is in a docking station, so there's only external DVI monitor in use. - After Linux has started booting, I open the laptop LID, and the internal LVDS has been turned on on clone mode with the external DVI display - and there's heavy flickering and distrortion on the internal LVDS display. - Distortion starts before Xorg is started. - After logging in to Xorg and running "echo low > /sys/class/drm/card0/device/power_profile" the distortion stops and the LVDS display is good/normal again.

Does it work properly if booted with the lid open? Yep, if I boot with lid open then it's fine - no flickering. I just tried multiple times with lid open. I just tried with the latest Fedora 16 Final RC1 (using Linux 3.1.0 final), and I noticed the LVDS flickering actually happens *sometimes* also when booting the laptop with lid open. So it's not actually always related to opening the laptop LID. Created attachment 52925 [details]

Same here on Acer Aspire 7560G (A8-3500M - Radeon HD 6620G) with Kubuntu 12.04 Beta 1 and external HDMI display (selected as main in xrandr settings). I didn't try yet boot with disabled LVDS, but I indeed have flickering on LVDS in some use-cases. For example every time when I use "carousel" KWin feature for switch between applications by Alt+Tab.
Issue is reproduceable even when I boot without external display.
The interesting thing I notice: issue reproduceable only with OpenGL version of KWin. I never can get it reproduced with OpenGL ES version of KWin.
Alex, I have the same issue or I need to fill separate bugreport?
