Bug Description
Binary package hint: gnome-power-manager
Sometimes, on my laptop running latest Jaunty, there is strange behavior. If I close and then open lid, the screen starts blinking endlessly, redrawing window decorations. It is highly annoying and makes laptop unusable.
Doing ctrl-alt-F21 does not help, reclosing the lid does not work.
The following messages fiull Xorg.log with the same frequency as blinking:
(II) PM Event received: Capability Changed
I830PMEvent: Capability change
(II) PM Event received: Capability Changed
I830PMEvent: Capability change
etc
What I noticed is that if I click on SCREEN BRIGHTNESS applet and bring up the slider for screen brightness, blinking stops while the slider is up.

There is a similar problem with those using 2.8.600 or lower version of the ATI drivers.
