SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
I upgraded from 5.27 to 6.0 using Discover and after a reboot I can't use the screen locker. It just shows the screen saying that I need to go to a TTY, login and type loginctl unlock-session 3 and then go back to the graphical session.

STEPS TO REPRODUCE
1. Upgrade from 5.27 to 6.0 via Discover
2. Reboot
3. Log in

OBSERVED RESULT
Locking the screen using the keyboard shortcut shows the screen saying that I need to go to a TTY, login and type loginctl unlock-session 3 and then go back to the graphical session.

EXPECTED RESULT
Screen locking should work as usual

SOFTWARE/OS VERSIONS
Linux: 6.5
KDE Plasma Version: 6.0
KDE Frameworks Version: 6.0
Qt Version: 6.6

ADDITIONAL INFORMATION
Booting from the latest Neon User ISO works as expected

I ran those commands about an hour ago and got several updated packages. After rebooting, I still experience this bug.

Comment 3 Harald Sitter 2024-03-01 17:37:52 UTC

I'd like to see the output.

I see the following when running them now:

Pretty sure we don't support that.

What you can try is to do the following:

sudo apt update
sudo apt install neon-desktop plasma-desktop neon-settings-2
sudo apt update
sudo apt dist-upgrade

Should that not change anything please paste the output again :)

I get the following (since it doesn't seem to install anything, I haven't rebooted afterwards):

I'm inclined to say the graphics PPA is causing graphics problems.

https://bugs.kde.org/show_bug.cgi?id=482070 Certainly makes it sound like something is wrong with your graphics driver.

I think you are correct. I followed the instructions here to uninstall the proprietary Nvidia drivers:

https://linuxconfig.org/how-to-uninstall-the-nvidia-drivers-on-ubuntu-22-04-jammy-jellyfish-linux

After rebooting, it solved the problem I reported in this bug report, so from my point of view this report can be closed now.

Cool. Thanks for the update.
