I am having difficulty understanding what the problem is, sorry. When you enter your password again, I would expect that it logs you back in again. Can you clarify the problem? Thanks!

The problem is that when I exit the session, I get a black screen and a message on the monitor out of range

Can you take a picture of the screen?

Thanks. That message comes from your screen itself. So there are two options here:

1. We are setting some screen parameter to an invalid value on logout, and then it gets set correctly again when the login screen appears

2. We're doing everything right, and your screen is malfunctioning out of spec.

The fact is that everything worked before, after the update it stopped, I have such a set - the nouveau driver, screen resolution 1280x1024x75hz

Is this reproducible in Plasma 5.27.5 or later?
