Further to my comment #4, in an Ubuntu session on Ubuntu 18.04 this setting is on the "Dock" tab of Settings.
I see the same problem as I originally reported although unlike with Ubuntu 20.04 I can change this setting as often as I like without having to use Dconf to unset the dock being shown on both displays. ** Tags added: bionic -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1866088 Title: Problems with the Dock setting of "Show on" in the Appearance tab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1866088/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
