Public bug reported: Using Ubuntu 19.04, with the vanilla gnome interface
gnome-control-center: 1:3.32.1-1ubuntu4 xserver-xorg-video-nouveau: 1:1.0.16-1 nvidia-340: 340.107-0ubuntu3 I switched from the nvidia display driver to nouveau. After rebooting the screen was low resolution. I attempted to open the gnome control center. It didn't open. I tried again from the command line with "gnome-control-center" and it crashed with an error message and a segmentation fault.
