Bug description:
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:

Here is lshal -m with gnome-power-manager killed and X correctly handling
the 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!
