Looking at the log file Daniel provided I'm not certain 30 seconds is enough:
ERROR: apport (pid 1657) Mon Feb 5 12:02:48 2018: called for pid 923, signal 5, core limit 0, dump mode 1 ERROR: apport (pid 1657) Mon Feb 5 12:02:48 2018: executable: /usr/bin/gnome-shell (command line "/usr/bin/gnome-shell") ERROR: apport (pid 1657) Mon Feb 5 12:02:48 2018: gdbus call error: Error: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files ERROR: apport (pid 1657) Mon Feb 5 12:02:48 2018: debug: session gdbus call: ERROR: apport (pid 1657) Mon Feb 5 12:03:04 2018: wrote report /var/crash/_usr_bin_gnome-shell.120.crash ERROR: apport (pid 1946) Mon Feb 5 12:05:58 2018: another apport instance is already running, aborting ERROR: apport (pid 1941) Mon Feb 5 12:05:55 2018: called for pid 1767, signal 6, core limit 18446744073709551615, dump mode 1 It is strange though that the crash file is written at 12:03:04. I wonder what is going on after that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1746874 Title: gnome-shell and Xwayland sometimes leave $HOME/core files (should be /var/crash files) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1746874/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
