Your logs show two (possibly separate) problems that will crash gnome- shell:
Oct 31 10:30:20 username-thelab gnome-shell[2666]: setup_framebuffers: assertion 'width > 0' failed and Oct 31 11:30:55 username-thelab gnome-session-binary[2598]: WARNING: Application 'org.gnome.Shell.desktop' killed by signal 11 So we need some more concrete information. Please forgive the canned response below :) --- Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a ".crash" file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer. If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart. Now open your file manager, navigate to your /var/crash directory and open the crash report you wish to submit. If this fails you will have to open a terminal and file your report with 'ubuntu-bug /var/crash/_my_crash_report.crash' where _my_crash_report.crash is the crash you would like to report. If you get an error that you aren't allowed to access this report you will have to file it with 'sudo ubuntu-bug /var/crash/_my_crash_report.crash'. ** Bug watch removed: GNOME Bug Tracker #789501 https://bugzilla.gnome.org/show_bug.cgi?id=789501 ** Changed in: gnome-shell (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1729028 Title: gnome-shell crashes after period of inactivity To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1729028/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
