Public bug reported: Xorg hangs, with high usage of CPU, typically around 95%. This happens at unpredictable intervals, sometimes 3 times in a day, sometimes not again for 3 weeks. Usually while watching videos, which happened this morning, causing me to submit this report. 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, start htop, and observe that xorg was consuming around 95% CPU. if you'd like to know what happened upon killing processes other than xorg, see my recent comments in Bug #1757299. This morning i didn't bother to yet again repeat the killing of other processes, but went straight to sending 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.
