Public bug reported:
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.
** Affects: gnome-power-manager (Ubuntu)
