Oooh... that was the login screen's Xorg shutting down. So Xorg exiting was not an error:
Okt 25 05:43:31 GS1 /usr/lib/gdm3/gdm-x-session[1302]: (II) Server terminated successfully (0). Closing log file. Okt 25 05:43:31 GS1 kernel: rfkill: input handler enabled Okt 25 05:43:31 GS1 gdm-launch-environment][1247]: pam_unix(gdm-launch-environment:session): session closed for user gdm Almost as if a VT switch has happened on resume. However we're now talking about a different problem to that in the bug description. The bug description talks about problems during login. But your title was "System freezes after suspend". So which bug would you like to discuss? ** Summary changed: - Xorg terminates (cleanly) on resume from suspend + System freezes after suspend ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete ** Changed in: mutter (Ubuntu) Status: New => Incomplete ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1797518 Title: System freezes after suspend Status in gnome-shell package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete Status in xorg-server package in Ubuntu: Incomplete Bug description: Linux Version: 4.15.0-36-generic After login or during login the screen freezes.
