Public bug reported:
Binary package hint: gnome-power-manager
Hi,
I'm using fully updated karmic beta amd64 on a Dell Inspiron 1520 with
gnome-power-manager 2.28.0 on linux kernel 2.6.31-13-generic. I have it
set in System>Preferences>Power Manager to always blank the laptop
display when the lid is closed. The respective gconf key is set to
always use DPMS off mode to blank the screen and turn off the backlight.
However, the display only stays of for 2-3 seconds, then comes back on.
I have observed that if I suspend or hibernate, after waking the display
behaves normally. If I kill gnome-power-manager, the display behaves
normally. [xset force dpms off] blanks the display normally.
The display behaved normally under Ubuntu 9.04.
Here is lshal -m although, I am not sure this is still relevant due to
devicekit. . . This is the lid being closed, waiting for the display to
incorrectly come back on, then opening the display:

blanking:

There is no difference I can see, so I would think that this further proves
that the problem is with gnome-power-manager.
If there is anything else I can do/test/post/try, please let me know.
Thanks!
