Every time I start a new session, when I return to the initial one (ctrl+alt+F7) I get black screen saying that screen locker is broken and I should go to virtual terminal and run "loginctl unlock-sessions".

I have 2 sessions running with different user accounts, and this problem occurs most of the time I switch between them. Searching online some reported that this might be a problem with: - a full root partition - tested and not the case - a full tmp partition - tested and not the case - a root btrfs partition reporting wrong space info - tested with both btrfs and ext4 and not the case I would appreciate it if you could confirm this issue and try to resolve it. A workaround is to disable the screen locker but I can only do that at home not in an office environment. Thanks. 1679177 5 max.hartert 2017-06-03 14:25:26 +0000 I am not shure if it is the same problem, since it does not involve a new session (I think). But lately my lock screen is broken too. The normal log in works fine. But once I lock my system or let it lock due to inactivity, I have to reboot the system. It also tells me to put in "loginctl unlock-sessions", which does not help. Currently I am on KDE 5.10, that is running on neon stable dev. I don't know since when I have this problem, but it can't be that long. Usually I won't lock my system at home, since I don't need to. 1681095 6 cfeck 2017-06-07 10:38:55 +0000 Maximilian, kscreenlocker 5.10.0 regression is tracked at bug 380491. Please check if it is fixed for you with 5.10.1, open a new ticket, if you still see an issue. 1684058 7 budinero 2017-06-22 14:19:25 +0000 (In reply to Christoph Feck from comment #6) > Maximilian, kscreenlocker 5.10.0 regression is tracked at bug 380491. Please > check if it is fixed for you with 5.10.1, open a new ticket, if you still > see an issue. I'm having the same problem as Maximiliam. It is not related to bug #380941 because there is no any password request, just a black screen with the folowing message "The screen locker is broken and unlocking is not possible anymore". The screenlocker background image is showed three times before the message. 1684059 8 budinero 2017-06-22 14:20:26 +0000 I'm using plasma 5.10.2 from Arch. 2042887 9 nate 2021-06-21 22:57:41 +0000 *** This bug has been marked as a duplicate of bug 407305 ***
