I'm not sure why this tagged as duplicate. In my case, the screen starts
flickering starts during boot up, and it doesn't even go to the login screen.
However, to bypass this flickering, after restart I hold the shift key pressed
and somehow get into the login screen. But even after logging, I still couldn't
use the system as it is response time is SUPER slow.
(unfortunately, moved back to windows now!!! :( )
