> 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.

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?
