Comment 8 for bug 431146

I'm not 100% sure that this is the same problem that I'm experimenting, but I think so.

When I turn on the computer and I log in, the display seems to go sleep when it is supposed to go.
However, after a while, the display stops going to the sleep mode when it is inactive and I can see the same icon, with the arrows in the corners, in the notification area.
I have been trying, for a long time, to find out what causes this change in the display behavior, but I couldn't understand what it is.

I noticed that, if I take out the laptop battery and put it again, or vice versa, the display starts failing to go to the sleeping mode. But I couldn't exactly notice a concrete pattern.

If I kill the gnome-power-management process and start it again, everything seems to work properly again.

I also saw the following when running the gnome-power-management in verbose mode:
"TI:23:11:17 TH:0x9146168 FI:gpm-manager.c FN:gpm_manager_idle_changed_cb,632
 - lid is closed, so we are ignoring ->NORMAL state changes"

Why does it say that the lid is close if it is open?
Maybe this has no importance... I don't know.

I have the screensaver disabled.

I have an intel integrated video chipset.

Thank you!
