Where to set time-out to lock desktop?

Ask Fedora
1

Using Fedora 36 workstation.

I cannot find the setting to only lock te desktop but not suspend.

How to I do that? Say after 15 minutes of no activity, the desktop should lock automatically.

  • it will be nice if Gnome knows I am playing a video, then it will pause the count down.

The gnome settings panel → privacy → screen lock
gives you the ability to change the screen lock and screen blank settings.

I don’t know exactly what criteria gnome uses to determine activity or inactive as far as playing a video.

It already does that, but it may depend on applications inhibiting the screensaver. For example, the builtin video player does inhibit the screensaver. Also, playing Twitch in Firefox inhibits the screensaver.

If you’re using mpv you’ll want to start with gnome-session-inhibit.

Another related question - which tools I can use to find out if any apps are inhibiting the screensaver timer?

It seems when I am running DosBox Staging, the screensaver is not activating even the machine is idle overnight.

This is the output of systemd-inhibit --list. My Gnome do not lock after idle for a few hours.

Which application is responsible?

can you look at:
~/.config/dosbox/dosbox-staging.conf

and change screesaver from auto to allowed

Changing screensaver to allowed works.

Thank you very much for your kind assistance!
