Thank you. After reviewing the Dash-to-Dock code myself I discovered another gsetting "multi-monitor". When "multi-monitor" is set to "true" the "preferred-monitor" setting is ignored. Changing "multi-monitor" to "false" has corrected the problem for me.
I am able to consistently reproduce the issue with Ubuntu 20.04. Changing the "Show On" setting in the Appearance UI to "All Displays" sets the "multi-monitor" option to "true" but when selecting a specific monitor the setting UI never clears the "multi-monitor" setting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871358 Title: Dock shows on all displays even when you don't want it to (because all displays are the same model of monitor) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1871358/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
