This is happening to me right now (On Ubuntu 19.10, kernel 5.3.0 and 5.3.9, nvidia drivers version 435 and 440)
It only happens when using nvidia GPU. If I prime-select my intel GPU then there is no issue. It seems related to the laptop display being on some internal display port that gets disconnected when the lid is closed. If I type 'systemctl suspend' before closing my lid everything works fine when I open. I suspect this is actually a bug in nvidia drivers and not in xorg- server -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1791981 Title: X Server session crash for "No space left on device" Status in xorg-server package in Ubuntu: Confirmed Bug description: Ubuntu Release: Ubuntu 18.04.1 LTS Package version: xserver-xorg: 1:7.7+19ubuntu7.1 When my laptop resumes after suspend, the desktop session crashes and a new one is started. So each time I lose all open applications and unsaved data! The expected behavior would be obviously to restore the suspended session.
