GDM Black screen after screen lock?

Question

linux

After locking the screen, everything as it should be shows GDM and the screen goes dark (or goes to sleep, in both cases this error). If I want to unlock the screen, for example, I press any key, the laptop kind of wakes up, but I see a black screen and a cursor. ctrl+alt+f2(3,4) works. If I change the session (ctrl+alt+f1) then I see GDM and I can go back.
