Screen locking is screen blocking :(

Fabian Wein
The issue of my blocked screen could not be solved by zypper dub
--no-allow-vendor-change (I'm up to date).

I have a TW KDE system with two screens and as far as I know nouveau
driver.

After some time of no use (lunch break/ night/ ...) my screen is
black, i see the mouse cursor (arrow, arrow with bar, ...) but no
login dialog appears.

I can switch to the console
systemctl status display-manager
shows a running dm.

init 3 followed by init 5 does not help.

systemctl restart display-manager lets me log in again.

I switched from sddm to kdm without solving the issue.

This happens since I updated a couple of days before after no update
for some weeks.

I disabled screen locking via Settings/Configure Desktop.

Anyone has an idea?

Thanks,

Fabian

Is it also missing on your second monitor? Happens to me occasionally also. Lockscreen missing on primary screen, shows up on secondary. I can log in normally from there.

is your primary screen on the *right*.  I have apps which do not recognize
which is the "primary" screen and/or which screen they last appeared,
especially on graphic start-up.

No, primary on the left, secondary on right, LVDS+VGA setup with different resolutions.

Huh, that's new. Out of ideas for that, sorry.

I know there is large time zone gap but has anyone an idea or a
workaround?

I assume the screen saver/locker is the problem. Is there another play
I can disable it?

This didn't work for me but hopefully it works for you.
sudo loginctl unlock-sessions

There might be a less destructive solution to get your session back:

    loginctl   # shows you a list of running sessions
    loginctl unlock-session 1   # use the number from the session list

I know this won't solve your main problem, but at least it avoids
killing all your running applications ;-)

Are you running Screen Energy Saving in systemsettings5/power management?  I
had a similar problem with my single screen if the screen powered down.  I've
turned the Screen Energy Saving off and it has so far been fine.

One last thing before really running out of ideas. Tried unplugging a monitor (try secondary?) and see if screenlocker shows up? It's a bit ugly but it worked last time I tried it (don't really remember).

The bug Cor found looks like being the issue. So I'll wait for the
next kernels or use an older kernel. I also switched off monitor
energy saving as Ian suggested (I didn't knew about the dialog), after
lunch I'll report if this helped.

Thanks to all of you for your help!
