GDM automatically suspends

Med · 2025-09-27 12:11:22

I am running a dual-seat configuration. Since updating to GNOME 49, I am having issues with the computer going to sleep 10 minutes after idling. I have disabled sleep for the gdm user:

sudo -u gdm dbus-run-session gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'nothing'
sudo -u gdm dbus-run-session gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 0

I have also edited /etc/systemd/logind.conf to set:

HandleLidSwitch=ignore
HandleLidSwitchExternalPower=ignore
IdleAction=ignore

None of this appears to work. I regards to timing, at boot, loginctl list-sessions indicates that the session is idle after 5 minutes and the computer goes to sleep exactly after 10 minutes. To address the problem I have set up a systemd inhibitor, but I prefer a cleaner fix. This worked fine with GNOME 48. Any idea? Thanks!

Possibly related to https://bbs.archlinux.org/viewtopic.php?id=308457 - is the problem gnome 48 or systemd 258?

I do not think the issue is systemd per se, as it only started after updating to GNOME 49. This being said I could try using another login manager to see whether this happens or not.

systemd and gnome updated pretty much at the same time. Did you explicitly test systemd 258 against gnome 48?

If not (or maybe in general) try to downgrade systemd to 257-9 to see whether you're with the other guys.
According to that thread, KDE etc are not affected and it's strictly Gnome + systemd 258 (+ nvidia? hybrid graphics?) and it would be interesting to see whether the second suspend is maybe actually triggered by the DM w/ systemd 258

Could somebody clarify what exactly do I need to change -
whether it GSettings or /etc/systemd/logind.conf, or both?

If this isn't https://bbs.archlinux.org/viewtopic.php?id=308457 its probably related to https://bbs.archlinux.org/viewtopic.php … 1#p2266271
