Title:
[nvidia] gnome-shell eats 100% cpu when seconds display is on and
screen is locked
Status in gnome-shell package in Ubuntu:
Invalid
Bug description:
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.
