I recently upgraded to Ubuntu 19.10, but I'm not able to open Settings.
killall gnome-control-center
gives
gnome-control-center: no process found
And also my laptop is hanging many times, I had to press the power button every time to restart.
gnome-control-center --verbose
gives
Segmentation fault (core dumped)
but gnome-control-center --version
gives gnome-control-center 3.34.1
echo $XDG_CURRENT_DESKTOP
