Public bug reported: Ubuntu: 16.04 xorg 1:7.7+13ubuntu3
Always reproducible, steps: a) start computer b) verify that Xorg is using some 0.7% CPU c) f1+ctrl+shift #go to virtual terminal d) f7+ctrl #back to the xorg Maybe 60 seconds mouse cursor can be barely moved, but keyboard and clicks are not responding after all. After that run script for monitoring CPU usage of Xorg. e) while [ 1 ] ; do top -b -n 1 | grep Xorg | awk {'print $9'} ; sleep 1; done CPU usage is almost 100% for 12...71 minutes and then calms down.
