I have Ubuntu 20.04 upgrade from 18.04, now every time I launch gnome-control-center, the initial window position is outside of the screen (right side), I have to used short key Alt + F7 to move into the screen to do the rest of settings.

I didn't have dual monitor.

I have tried reset all the settings by the following methods, but it didn't work.

$ dconf reset -f /org/gnome


$ gsettings reset-recursively org.gnome.shell

Similar issue happened in gnome-nautilus, but I got this fixed by

$ gsettings reset-recursively org.gnome.nautilus

How to make an gnome app initial window location to its default values?


From your brief description, it sounds like your gnome-control-center window is launching to another workspace than you'd like.

If that's really the case, hit ALT+F7 to move into the "screen" where the gnome-control-center window is, then hit the SUPER key, click and drag the gnome-control-center window into the desired workspace on the right side of the screen. Click SUPER to close the overview.

  • I looks like the app is launched into an unknown display. I saw there is an unknown display plus a builtin display under the Display setting entry. I guess the nvidia driver not work properly after upgrade. After do ubuntu-drivers devices to check and sudo ubuntu-drivers autoinstall to install, then reboot, the unknown display is gone, only one builtin display, and all apps work fine now.
