Thanks Sebastien, I'll mark this one as verified on the basis that the dock can be moved freely from one display to the other and back, and that no crash occurs.
I've created bug 1877108 for the incorrect reporting of which display the dock is currently being shown on. ** Tags removed: verification-needed-focal ** Tags added: verification-done-focal -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell-extension-ubuntu-dock in Ubuntu. https://bugs.launchpad.net/bugs/1866088 Title: Problems with the Dock setting of "Show on" in the Appearance tab Status in gnome-control-center package in Ubuntu: Fix Released Status in gnome-shell-extension-ubuntu-dock package in Ubuntu: Won't Fix Status in gnome-control-center source package in Focal: Fix Committed Status in gnome-control-center source package in Groovy: Fix Released Bug description: I use a laptop with external monitor in a dual display set-up. The "Screen Display" tab of Settings application correctly shows: Display 1 as the built-in display Display 2 as the external monitor If I go to the new "Appearance" tab I see that the Dock is set to display on the Built-in display but it is actually being displayed on the external monitor. If I change this setting to display on the external monitor it displays on the laptop's built-in display. Once set to "All displays" the setting can not be unset and the dock insists on being displayed on both the laptop's built-in display and the external monitor. I used the Dconf editor to set org.gnome.shell.extensions.dash-to-dock.multi-monitor to off to correct the problem although the settings application again shows that the dock is being displayed on the built-in display when in fact it is being shown on the external monitor.
