Autosuspend not working but manual suspend works

I can run systemctl suspend and the system will go to sleep perfectly.

I have dim screen at 30 seconds. I have when inactive: sleep 1 minute.

If I wait 1 minute, I see the screen dim at 30 seconds, however at the 1 minute mark I get this in journalctl -b0 -f
Feb 03 10:47:30 endeavorOs systemd[1]: Started dbus-:1.2-org.kde.powerdevil.wakeupsourcehelper@1.service.
Feb 03 10:47:40 endeavorOs systemd[1]: dbus-:1.2-org.kde.powerdevil.wakeupsourcehelper@1.service: Deactivated successfully.

Yet nothing happens, there is no sleep.

Some more information:
$loginctl show-session “$XDG_SESSION_ID” -p IdleHint -p IdleSinceHint
IdleHint=no
IdleSinceHint=0

Hi, and welcome to the comunity

It looks like your problem is similar to the issue(s) described here https://bugs.kde.org/show_bug.cgi?id=510992#c8

TLDR kernel bugs exposed via improved KDE functionality

The proposed workaround is to remove the executable bit from wakeupsourcehelper

sudo chmod -x /usr/lib/kf6/kauth/wakeupsourcehelper

[moonriver]

Unfortunately I already did that and the comments at the end of that thread are from me.

Removing x from wakeupsourcehelper ends up with these errors:

Oh, alright, I see. May I propose another workaround then.

You were saying that invoking systemctl suspend works fine, so in the Power Management settings in the Other Settings section, select run condition “When inactive” and enter systemctl suspend command with a a different timeout, say something like 55 seconds

It might work. Good luck.

[moonriver]

That does work as a workaround! Thank you very much.

[moonriver]

Well, unfortunately, the Other Settings, when inactive does not take into account if a video or other source is blocking sleep and will only execute based on time since last input. Meaning it will sleep while watching a video. So not quite a solution but thanks for the help regardless.

[jake99]

Ah, KDE, always missing the details.
It’s not a big deal, we can create a small script that will check if there are any inhibitions before suspending

The one-liner for you

#!/bin/bash
[ "$(busctl --user call org.kde.Solid.PowerManagement.PolicyAgent /org/kde/Solid/PowerManagement/PolicyAgent org.kde.Solid.PowerManagement.PolicyAgent HasInhibition u 1 | awk '{ print $2 }')" = "false" ] && systemctl suspend

Save it to a file, make the file executable, and use it instead of systemctl suspend command.

Disclaimer, have not tested this thoroughly, you may need to adjust it to your needs.

Based one liner thank you. Marking as solved! Thank you!!!
