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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791981 Title: X Server session crash for "No space left on device" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1791981/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
