Public bug reported:

Or: "Why is DPMS off for my screens ?"

I just travelled a quite long journey to find out why my computer
wouldn't go to sleep anymore. I first tried to follow the steps given
here: https://wiki.ubuntu.com/DebuggingGNOMEPowerManager with little
luck (as I have a standalone computer, I don't have much upower traffic)
so I focused on gnome-settings-daemon (whose --no-daemon options just
don't work).

After much research, I found out that the power plugin just didn't
start. Looking in the code (gsd-power-manager, I try to find anwers
where I can), I noticed that if the power-manager cannot clear dpms
timeouts, the manger just didn't start.

So I issued a: xset q | grep -A1 DPMS
DPMS (Energy Star):
  Standby: 360    Suspend: 360    Off: 420
  DPMS is Disabled

and indeed my DPMS is disabled. Enabling it then restarting gnome-
settings-daemon (killall then start with --no-debug) I see that the
power plugin starts just fine and my computer goes to sleep as expected.

I checked xorg.conf that DPMS option was present and it is indeed.

So my question is: "Why is DPMS off for my screens ?"
I'm also wondering why the power plugin could start if DPMS is off ?

I must add power-wise information: my kernel starts with "noapic" option
otherwise, my computer won't resume.
