Plasma 5.16 wont lock right when laptop lid is closed

My Arch install with Plasma with display manager gdm wont start the KDE lock screen correctly when I open the lid from suspend. Is there any fix to this? This really does concern me.

Re: Plasma 5.16 wont lock right when laptop lid is closed

What does "won't lock right" mean? How does this show itself, post your journal after such a locking situation. FWIW GDM is a lock screen and KDE has a lock screen, I don't know if there's an option to disable GDM from trying to be a lock screen, but if there isn't you might be better off using another display manager that doesn't try to be a lockscreen itself.

Edit: try something like

sudo -u gdm dbus-run-session  gsettings set org.gnome.desktop.lockdown disable-lock-screen 'true'

Also is this a wayland session and if so did you try xorg?

Mod note: Moving to NC

Not a wayland session. What I mean is that When I open the lid of my laptop, the session doesn’t show the lock screen and goes straight to the desktop. Which is a huge security risk. Also would like to add that this is mostly happening on battery instead of ac

Did you try what I mentioned wrt GDM? What's your output for

systemd-inhibit --list

Wrap output in [ code ][ /code] tags (without the spaces) and don't bump your post

Did you reboot after executing that command? If it still fails even after reboot, get GDM out of the picture, and use normal a configured startx, or if it has to be a DM use sddm.
