Public bug reported: on my laptop (xiaomi notebook pro), ubuntu 18.10 amd64, standart ubuntu desktop (gnome-shell), no application running just activate second display in gnome tweak, let it lock itself the fan is going fast, simply moving the mouse and the fan slow down. wrote a simple script to append a top every minut in a log file, show that gnome-shell consumes 100% when locked. workaround : disabling second displaying and no more CPU usage / fan noise when locked.
