Bug 291955 – kde-base/kwin-4.3.3 sometimes gets confused when connecting/disconnecting power adaptor from laptop (compositing on/off)

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Biker 2009-11-05 09:56:15 UTC]

When I disconnect the power adaptor from my laptop, KWin  gets confused and the screen goes black.

Reproducible: Sometimes

Steps to Reproduce:
1. Unplug the power cord from your laptop

Actual Results:  
When I disconnect the power adaptor from my laptop, KWin gets confused and the screen goes black; reconnecting the power adaptor doesn't help. Whenever I do that (disconnecting the power) kde tries to disable compositing and sometimes it succeed and sometimes not. When everything goes black, I have to press Alt+Shift+F12 to disable compositing and get an usable desktop back. However, if I try to switch compositing back on, everything goes black again. The only way to get kde back to normal is to issue the command kwin --replace from a konsole shell.

Expected Results:  
When unplugging the power, kde should disable compositing and when reconncting the power it should turn it on again, without ever turning my screen black.

I am now running kde 4.3.3, but the bug has been there since at least kde 4.2, probably even before that.

My hardware is a thinkpad T500 with an intel video card.

Do you still have this problem with kde 4.3.5 or 4.4.2?
Please attach your xorg.conf and Xorg.0.log
