In at least one instance I've seen a system from a user POV completely break because of that as it failed to get any keyboard input. Forcing xorg to get properly installed fixes any and all issues as expected. - devel upgrade from xenial to bionic - restart - xorg not upgraded - try to get a hold of tty or repair mode - sudo apt install dist-upgrade && sudo apt install xorg - restart - working system I am going to attach logs for an ubuntu-desktop system, but I've also seen this with kubuntu-desktop and the derived neon-desktop. It's a bit unclear to me why apt is having trouble with the resolution, it does seem like a fairly serious problem though.
