Yes if you're using Xorg (the default "Ubuntu" session) then mouse cursor movement is done by the Xorg process so it will keep moving even if gnome-shell was frozen.
I meant that you should run 'top' before the problem happens and leave it running so you can watch that window. When the problem happens is it only keyboard input that freezes or window contents too? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1807056 Title: Occasional Keyboard freeze Status in gnome-shell package in Ubuntu: Incomplete Bug description: I am using 18.04 and sometimes, whatever I type does not work. It is as if there is no keyboard connected while I have my laptop keyboard and an external keyboard connected to the machine. I even enabled On Screen Keyboard and tried to type through it.
