just had a lockup watching a youtube video in firefox-esr. i did something extremely simple, i think it was push the pavucontrol window behind the firefox-esr window, which did so, but immediately thereafter the video image froze, the mouse could still move the cursor but the mouse and keyboard were otherwise unable to get any response, not even to ctl-alt-Fn, nothing visible would be expected from ctl-alt- PrintScreen-s, saw no response to ctl-alt-PrintScreen-e either, nor, surprisingly, to ctl-alt-PrintScreen-k. The sound played on via pusleaudio and bluetooth into my headphones for 2 more minutes, then it fell silent. After 10 minutes it all remained thus. i tried to login via ssh but unfortunately my phone was connected to mobile data but not wifi so i presumed ubuntu was not responding via ssh either, heck it likely would have if the phone's wifi radio was enabled. well this occurrence does serve the purpose of verifying that the problem does occur in bionic either while playing video or not playing video. the system did respond to ctl-alt-PrintScreen-b and booted up normally.
in /var/crash all i found was a file named .lock, zero length, dated 3-22 12:42:30pm. dunno what that's from, curious, no bash history survived from that day, this is what i found from around then in syslog: Mar 22 12:17:01 op755 CRON[7216]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) Mar 22 12:42:28 op755 kernel: [76631.137616] Web Content[4830]: segfault at fffe8 ip 00007fc182a1aab1 sp 00007ffee816bb10 error 4 in libxul.so[7fc17ee30000+4e30000] Mar 22 13:01:54 op755 bluetoothd[577]: /org/bluez/hci0/dev_00_0C_8A_AA_FE_70/fd1: fd(36) ready Mar 22 13:01:55 op755 rtkit-daemon[4718]: Supervising 1 threads of 1 processes of 1 users.

xorg in Ubuntu. https://bugs.launchpad.net/bugs/1757299 Title: [Dell OptiPlex 755] Intermittently GUI hangs with high xorg CPU% after launching applications Status in xorg package in Ubuntu: Incomplete Bug description: The problem is that after launching a few applications, the GUI may become unresponsive, although this is not consistently reproducible. When the GUI is unresponsive, it is correlated to high CPU utilization of xorg. An example reproduction scenario is launch the following in order, and quickly: startx xterm via twm another xterm via the first xterm tmux firefox-esr bluetooth-manager pavucontrol While the above are launching, maximize the xterm running tmux, and the GUI immediately becomes unresponsive. For example, Ctrl+Alt+Fn don't respond. After this, I logged in via ssh, attached to tmux, launched htop, copied htop output, which shows xorg at 94.6 CPU%.
