Can't Lock My Screen

bsucker98

I'm not sure what caused the issue, suddenly I couldn't lock my screen, neither with the shortcut(Super + L) nor via the applet. But Automatic Screen Lock works 30 seconds after Blank Screen.....

So I ran journalctl -f and then pressed <Super> + L
Then I get an error saying
Couldn't lock screen: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.Shell.ScreenShield was not provided by any .service files

I have no idea what to do, tried googling multiple ways and never got a solution 🙁

Is this on Budgie or GNOME Shell?
If you are using Budgie, can you check if budgie-screensaver is running by doing ps -aux | grep 'budgie-screensaver'?
If you are using Budgie, do you also have GNOME Shell + GDM installed? This will negatively impact the ability to reliably lock the screen, despite various measures I implemented in budgie-screensaver to kill off the gjs gnome shell process.

Yes it is running when I checked

Oh I never knew that, I have installed both GNOME shell and GDM...maybe that's what causing the issue, It seems the issue came after a recent big update (I'm not sure), Because I had installed Gnome for about 6 months and never had any lock screen issues...

Thanks Josh, imma uninstall Gnome and see

JoshStrobl Thank you so much, this saved my day!

bsucker98 Yea it is the result of a change they made in GNOME Shell 40 unfortunately. If you uninstall gnome-shell and GDM, and install lightdm + slick-greeter, you should be able to lock your screen again, at the very least through the User Indicator applet. Not sure about the automatic screen lock though or shortcut though, I honestly use neither.

Aha now it all works nicely...not an issue, for some reason still after removing Gnome, it shows as an option to choose from in slick greeter 😄
