The screen locker is broken and unlocking is not possible anymore

[elgalu]

When using NOVNC_ENABLE=true we get the screen locked after some time showing a black screen with The screen locker is broken and unlocking is not possible anymore does anyone knows how to get passed this?

Using: ghcr.io/selkies-project/nvidia-egl-desktop:latest

I was going to remove the locker altogether. In the backlogs.

[elgalu]

cool! do you know how can we remove it manually for now?

https://www.simplified.guide/kde/lock-screen-configure For now.

[elgalu]

ok I was able to restore it via the command line and without rebooting:

kwriteconfig5 --file ~/.config/kscreenlockerrc --group Daemon --key Autolock false
killall ksmserver plasmashell

Unfortunately, this commit has an edge case; what if someone mounts a PersistentVolume or any other external filesystem in the home directory? Some careful examination is required to make this work in all cases.

We need something like this to configure globally in the system directories: https://www.reddit.com/r/kde/comments/r4yey1/systemwide_config_for_all_users/hmkz0g0/

Or, one other option is to (somehow) safely remove kscreenlocker without touching anything else.

This is not possible. Global configuration is required.

@elgalu

Could you do me a favor and see if after installing kubuntu-settings-desktop, then doing (with root) kwriteconfig5 --file /usr/share/kubuntu-default-settings/kf5-settings/kscreenlockerrc --group Daemon --key Autolock false works for you?

This is the default state:

root@xgl:/usr/share/kubuntu-default-settings/kf5-settings# cat kscreenlockerrc
[Daemon]
Autolock=true
Timeout=15

[Greeter]
WallpaperPlugin=org.kde.image

Should be changed to:

root@xgl:/usr/share/kubuntu-default-settings/kf5-settings# cat kscreenlockerrc
[Daemon]
Autolock=false
Timeout=15

[Greeter]
WallpaperPlugin=org.kde.image

[KDE Action Restrictions][$i]
action/lock_screen=false

in /etc/xdg/kdeglobals might work systemwide. Not sure.

I think this commit works. @elgalu Please close if it does and tag me if it doesn't.

[ehfd]

It should work. Please reopen if there are any issues.
