Hello,
I'm having an issue where the administrator account of my installation is not lockable from the power menu.
I click 'lock' and not a thing happens, but all other functions (logout etc.) work perfectly.
Strangely, I don't have this problem on the other non-admin account on this install which goes to the lock screen without issue.

Is there a way I can diagnose this? Or is this a feature rather than a bug.

Il have the same issue, impossible tout lock. 😮

I just tried this in raven and it worked. Clicked lock and it locked me out of the OS, requiring a password to get back in to the OS. I didn't see where the admin stuff was relevant. Maybe a bug or update thing?

By admin account do you mean you're logging in as root or you mean an account with sudo priveledges?

    I'm having the same problem. Super+L and clicking on "Lock" don't do anything.

    Locking via shell works however with:

    dm-tool lock

    but not with:

    gnome-screensaver-command --lock

      Exactly the same comportment than seagle describe with my normal account (sudoer).

        @ All user affected: What desktop environment are you running?

        Works fine for me. Latest Solus Budgie.

          It's interesting. All users here have an updated Budgie.
          2 users have a lock that works.
          The rest do not.
          If we were all running WIN I would easily guess "software conflict", when apps regularly over-rode the settings of another app.
          Does such a thing as software conflict exist in solus/linux I wonder?

          By running gnome-screensaver in debug mode like this:

          pkill -f gnome-screensaver
/usr/bin/gnome-screensaver --no-daemon --debug &

          I noticed this output in the shell when trying to lock

          [listener_lock_cb] gs-monitor.c:209 (10:02:48):	 Locking disabled by the administrator

          Which got me to check org.gnome.desktop.lockdown via gsettings

          $ gsettings get org.gnome.desktop.lockdown disable-lock-screen
true

          This nees to be set to false

          sudo gsettings set org.gnome.desktop.lockdown disable-lock-screen 'false'

          Now locking the computer is working normally again for me.

            seagle Late reply, but you cracked the case Seagle! Although I had to solve the problem using a slightly different gsetting command - thought I'd post here in case anyone else encountered this foible.

            By running the following command I confirmed that the value for Gnome's desktop lockdown setting was 'true' when it should be 'false'.
            sudo gsettings set org.gnome.desktop.lockdown disable-lock-screen 'false'

            I tried to set it to 'false' using the set command but no dice for some reason, so I used the reset command which did the trick.
            gsettings reset org.gnome.desktop.lockdown disable-lock-screen

            The GUI lock function now works! Though the behaviour of Solus's locking system does seem slightly weird - I wonder why after locking and switching users, getting back into your account requires logging in on the home screen, and then typing the same password into the still active lock screen... seems a bit redundant to me as you've already proved you have the right credentials on the home screen.

                trenchanter the "reset" probably makes more sense anyway than manually setting it to "false".

                  Sorry for the late reply, but I was having the exact same issue after last Friday's software update. trenchanter your solution did the trick to solve the lock issue. Thanks!
