Just to let you know, my problem was a slight different message: "Failed to start X Wayland: Wrong ownership for directory "/tmp/.X11-unix" And the "/tmp/.X11-unix" directory had the right permissions. Turns out the message is quite misleading in my case because the problem was actually in "/tmp" itself being owned by my user and not root. I think at least the message should be clearer.
