Can't login after lock screen (black screen)

Question

After locking screen and monitor going into sleep mode, I can't get the login screen anymore, the monitor stays in sleep mode forever. In previous Ubuntu versions after pressing any key or the mouse, the login screen showed up, but not anymore. I have to restart the computer.

How can I fix this issue?

Thanks.

Crtl+Alt+F7 doesn't work with me. I tried all the workarounds I could find online but none works. I'm always stuck with the black screen.

Please let me know the result (good or bad) if you decide to use this workaround. There are a lot of other users in the same situation. I do not want to leave any "workarounds that don't work" lying around wasting people's time. : )
