After upgrading my PC froze right after finishing. After grub i either get a black screen with blinking cursor in the top left corner or “Failed to start Light Display Manager”.
I already tried reinstalling xorg, lightdm (and tried gtk, sddm), and gpu drivers. Nothing. Still “Failed to start Light Display Manager”. Any ideas?
I’m inclined to get you down to a bare system and build back up from that, but as a new user, that might be too much for now. So for starters, see if this works for you: purge lightdm from your system, then install xdm instead.
Let’s not get too far ahead, take a step at a time!
