Public bug reported: This bug report is highly similar to Bug #1770250, except that this time i made sure to launch ubuntu-bug xserver-xorg before relaunching xorg, just in case that provides packaging of better information. This morning xorg froze again while watching a video. Watching a video seems to bring it on more than not, tho it does sometimes happen without watching a video. And FWIW i think fairly heavy swapping activity is also often involved in eliciting this hang bug. This morning, as in several earlier occurrences, the video image froze except that i was able to move the mouse cursor, however window borders did not change as they normally would when the mouse cursor travelled in and out of windows. Onscreen interactions such as trying to show the twm root menu or move or iconize windows, or keyboard keys such as ^L to the browser or even ctl-alt-F2 or ctl-alt-F3 all failed to produce their usual response. i was able to login via ssh, attach to tmux, and via htop observe that xorg was consuming around 95% CPU. i then sent signal 3 to xorg, after which ctl-alt-F2 and ctl-alt-F3 were again operational, and i found the attached report in /var/crash.
