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.
