Lock screen isn't working correctly

I’ve found two issues:

  1. Last night, I put my pc into sleep mode. But when I opened it again, it didn’t ask for the password.
  2. The network applet in the system tray locks everything until it get connected to Wi-Fi, even the lock screen. The desktop is visible with all the windows opened. Only when it gets connected to the internet, the log-in screen appears.

No, it works correctly, but the bottleneck is rather your HDD:

Note that the “lock screen” is an additional program. So on kde it is sddm.

If you lock the screen and then suspend, then it should work as intended.

If you look at:

systemctl list-dependencies graphical.target

Each Services on a target run in parallel, but targets run in steps.

You see that NetworkManager.service is part of multi-user.target.

Now I guess the services NetworkManager-wait-online.service is the stopper,

systemctl list-dependencies NetworkManager-wait-online.service

which depends on NetworkManager.

So at the end: It will not start the “lock screen” until it has a internet connection on wakeup. The “screen lock” have to be started and then suspend. On wake up the screen lock appears normally then.

On fast SSDs you will not experience that issue, but on slow HDDs.

Then please change the suspend button behaviour of the application launcher.

You ask me, who is not a dev of kde and not part of ManjaroTeam and even don’t use KDE Plasma at all, to change it? Hmhm :thinking: I am the wrong person.

Report it upstream to the kde devs. That would be a better advice, since Manjaro doesn’t develop KDE, or change it yourself.

However… just think that a lock screen on Xorg is a hacky thing. Wayland seems not to have this problem. Maybe try that, but on the other side wayland is still in progress of development, so expect not a 100% bug-free environment.

EDIT: On I3 with a slow laptop on a 5400RPM HDD I experience the same with blurlock, but it doesn’t happen with GDM and Gnome on the same machine (when I remember correctly). So might a specific plsama and sddm problem.
