When I first installed Xubuntu on my system, it would automatically suspend after the set idle period no problem. But I seem to have changed something and its no longer working.

I've checked the usual suspects, first and foremost being that I have actually set it properly in xfce4-power-manager which I think I do:

Xfce Power Manager Settings

When I run systemd-inhibit --list --mode=block I get the following:

WHO                 UID  USER      PID  COMM            WHAT                                                                       WHY                                      MODE
xfce4-power-manager 1000 doctor_ew 1192 xfce4-power-man handle-power-key:handle-suspend-key:handle-hibernate-key:handle-lid-switch xfce4-power-manager handles these events block
xfce4-power-manager 1000 doctor_ew 1071 xfce4-screensav idle                                                                       Inhibit requested                        block

2 inhibitors listed.

But I'm not sure if I'm supposed to be seeing that or not. Are there any other troubleshooting steps anyone can recommend, I'm not sure what else I could check at this point.

I have the same inhibitor displayed when enabling the "presentation mode" of the power managment widget in my dashboard. You may have activated that.

  • THAT WAS IT. I actually had to enable that widget just to check, so I have no idea how it got accidentally toggled, but sure enough Presentation Mode was enabled. Thank you very much for posting, I never found any mention of that in my research.

The first inhibitor is ok, but the second should not be there. If I check ps ax | grep screen I get:

1135 ?        Sl     0:00 /usr/bin/xfce4-screensaver --no-daemon

So our configurations must differ. I've setup my power manager the same way you do. The /etc/systemd/logind.conf should be disabled throughout all entries:

[Login]
#NAutoVTs=6
#ReserveVT=6
#KillUserProcesses=no
#KillOnlyUsers=
#KillExcludeUsers=root
#InhibitDelayMaxSec=5
#HandlePowerKey=poweroff
#HandleSuspendKey=suspend
#HandleHibernateKey=hibernate
#HandleLidSwitch=suspend
#HandleLidSwitchExternalPower=suspend
#HandleLidSwitchDocked=ignore
#PowerKeyIgnoreInhibited=no
#SuspendKeyIgnoreInhibited=no
#HibernateKeyIgnoreInhibited=no
#LidSwitchIgnoreInhibited=yes
#HoldoffTimeoutSec=30s
#IdleAction=ignore
#IdleActionSec=30min
#RuntimeDirectorySize=10%
#RemoveIPC=yes
#InhibitorsMax=8192
#SessionsMax=8192

  • This is my home gaming server, so I've got the screensaver completely disabled, as well as logind.conf with all disabled. I tried killing the unused screensaver process, but it still hasn't gone to sleep. I know its wrong but I think I'm going to try killing the power manager too. No inhibitors == sleep right? If that works at least I can narrow down my troubleshooting. Thanks for the help btw!

  • Yes, the screensaver may not inhibit the power manager. If it helps, you could accept my answer

  • Sorry forgot to reply, I tried getting rid of the screensaver inhibitor and its still awake. I'm still digging into it and I'll keep updating this question if I find anything
