[Bug 1916005] Re: gnome-shell hangs window decorations and dialogs
Thanks for the bug report. Please try uninstalling the 'hidetop...@mathieu.bidon.ca' extension. If that doesn't fix the problem then next please check for crash reports using these instructions: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment Finally, if there are no crash reports then next time the system returns from a long hang (without rebooting) run this command: journalctl -b0 > journal.txt and attach the resulting text file here. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1916005 Title: gnome-shell hangs window decorations and dialogs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1916005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1916005] Re: gnome-shell hangs window decorations and dialogs
disabling makes freeze duration much shorter but you lose your desktop session every time. DATA LOSS inevitable. sudo perl -p -i -n -e "s/enabled=1/enabled=0/" /etc/default/apport sudo systemctl disable apport sudo service apport stop If I remove apport and whoopsie, then the duration of the freeze is reduced to 5 seconds under light load and desktop is not lost. This uninstalls ubuntu-bug as well. sudo apt-get purche apport whoopsie The system still freezes and under load it could be much worse. Gnome- shell is apparently still crashing but it isn't compounded by apport delays. If I reinstall apport but not whoopsie, I still have the long delay. cat /proc/sys/kernel/core_pattern |/usr/share/apport/apport %p %s %c %d %P %E If I change it to coredump, gnome-shell still crashes the whole desktop sudo bash -c 'echo "core" >/proc/sys/kernel/core_pattern' If I change it back and then purge apport, it changes the pattern to: !/usr/share/apport/apport %p %s %c %d %P %E And gnome-shell crashes somewhat gracefully, allowing you to keep your desktop. What happens under system load remains to be seen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1916005 Title: gnome-shell hangs window decorations and dialogs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1916005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1916005] Re: gnome-shell hangs window decorations and dialogs
Mouse cursor works when frozen. Actually, it looks like psensor does hang until the system starts to come back. It does show a spike (of unknown amplitude) in CPU usage (tenfold) and CPU temperature and there is an audible increase in fan speed. Top/gnome-terminal also freezes. top -d 1 -p `pgrep gnome-shell|paste -sd,` If I run a command in a terminal that writes the date once per second and tee's it to a file, the terminal output will freeze immediately when desktop freezes but the timestamps in the file show it still continues to write to the file on time. CPU pressure was not high but CPU usage was fairly high but not on all cores simultaneously. Duration of freeze on lightly loaded system was around 25 seconds. Quickly switching to another console and running top shows apport and whoopsie-upload at top of CPU usage. Turning off Settings -> Privacy -> Problem Reporting -> Send Error reports to canonical changes nothing. apport/whoopsie-upload still run and eat 100% of cpu. + -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1916005 Title: gnome-shell hangs window decorations and dialogs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1916005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
