The issue is pretty consistent, almost every time when I boot I see black screen. I found 2 simple workarounds:
- press "Sleep" button and then immediately wake the PC up
- press Ctrl + Alt + F3 to switch to console-mode and then Ctrl + Alt + F1 to switch back to GUI
Then login screen appears as it should.
What can be the issue and how to fix it? P.S.: I use official NVIDIA driver instead of Nouveau.
