Description

Even with all idle-related options in DankMaterialShell set to Never, my system still ends up suspending or returning to the login screen as if an idle action was triggered.

Important details:

• In Energy & Security → Idle settings I have:
  • “Lock automatically after” = Never
  • “Turn displays off after” = Never
  • “Suspend system after” = Never
• systemd-logind is configured to ignore idle actions and sleep/lid keys via a drop-in.
• hypridle is installed but disabled and not running:
  • The user service is inactive (dead),
  • There are no hypridle processes,
  • It is not referenced anywhere in my Hyprland config.
• There are no other idle daemons configured to manage suspend/lock as far as I know.

From my point of view as a user, what happens is:

• After some time, the session either suspends or drops back to the login/greeter as if an idle timeout had fired.
• This can happen even while Steam is downloading games (so the system is not completely idle).
• It feels like something in DMS (IdleMonitor / session handling) is still triggering a suspend or session close despite the GUI showing “Never” for all idle actions.

I also applied a workaround by masking the suspend-related systemd targets so that nothing can call systemd suspend, but I would like to understand/fix the root cause.

Expected Behavior

With:

• DankMaterialShell idle settings (lock automatically, turn displays off, suspend system) all set to Never, and

• systemd-logind configured like this:

  [Login]
  IdleAction=ignore
  IdleActionSec=0
  HandleSuspendKey=ignore
  HandleLidSwitch=ignore
  HandleLidSwitchExternalPower=ignore

I noticed this happens when I turn off my screen; the system goes into sleep mode immediately after shutting down. Is there something I need to change? I'm using an RTX 5080.

Same issue here.

Are you all on hyprland or something different?

And coudl you share ~/.config/DankMaterialShell/settings.json - you can strip location coordinates from it if you have it for gamma or whatever, for privacy.
