Olá,
Yes, I can log in the TTY and get the logs (see bellow). The last lines before the locker freezes to death are also those about “kscreenlocker_greet”. In the terminal I am also able to kill the locker (only with -9). Then the locker respawn and work again (albeit the profile image appears square, not the usual round).
It is an annoyance but it is not a big problem, and I am still investigating (amateurish) possible reasons in my spare time. One difficulty is that it seems random, and I am unable to reproduce. Apart from this, the machine works very well all all the time which I believe reduces the chance to be a problem with hardware, such as fault memory or power. The last clue was perhaps something to do with different Qt libraries in the system?
Thank you for your answer. Bellow is a copy from a poster with the locking problem and more information.
“” I am having this problem in my (old) system since the upgrade to Leap 15.5. The screen lock freezes and I am unable to type anything. The mouse works, with the pointer visible and moving, but I cannot click anything and even the blinking cursor in the password box is frozen.
The unlock-session(s) in a terminal does not work. Killing the process kscreenlocker_g with only “kill ####” does not work and I have to do it with -9 (“kill -9 ####”). Then the process respawn and I am able to enter the password again.
The only messages I got related to the locker are these:
sudo journalctl | grep kscreenlocker
May 04 08:22:33 XXXX.site kscreenlocker_greet[10383]: Qt: Session management error: networkIdsList argument is NULL

Other error message is “gkr-pam: unable to locate daemon control file”, but this does not seems to be related. I have Nomachine running (remote access), but the freezes occurs with the server disabled. I used the “light-locker” a few times, and it seems that the problem did not occur.
Does anyone have any idea why this is happening, or were I can find more information about errors in the system logs? Is it possible to “reinstall” (clean) the kscreenlocker? I will be glad to give more information if necessary.
