STEPS TO REPRODUCE
1. Have a time out for the screen to dim and turn off;
2. Wait until the screen dims and arrive the time to turn off;
3. As the screens turns off move the mouse to stop it middle way.

OBSERVED RESULT
By the activity led on the notebook you can see that the system is processing "something", it takes a few seconds to react and for the screen turn on again and show the lock screen. The lock screen don't reactive. Mouse and keyboard input don't unlock the screen or shows the interface to unlock with a password.
My turnaround as using KDE Connect and send the command to unlock the screen. It worked partly because nothing would react to my mouse and keyboard inputs.
My solution was to use KDE Connect to lock the screen, making it lock correctly this time and restart to react to my inputs.


EXPECTED RESULT
After screen turning on again the lock screen would accept my inputs.

Seems to be one of those things that "may" happen, but not happen every time.
Before replying I tested three times. Two times nothing happened, but one time it did. It didn't get stuck on the login screen like like last time, it just came back to the desktop but while I moved the mouse the screen flickered a lot. Bringing up a program windows stopped the flickering.

Once in a while I'll test it, but at least it's something that may happen on my system (fully up to date).

Yeah, I also cannot reproduce the issue, sorry.
Comment 4 Nate Graham 2022-11-04 21:25:10 UTC
Can you try again with the new Neon rebased on top of Ubuntu 22.04?
Comment 5 paninomaninodesu 2022-11-05 00:32:28 UTC
The problem did happened, I tested to confirm and that's why I made this bug report. But with time didn't happened again, though I didn't keep testing. If there was a real problem it should be fixed by now somehow.

I tried it now, both on X11 and Wayland and didn't happened. I think it's fixed.
However I need to mention that I'm on another notebook now.
