Sorry I should have posted an additional comment yesterday. This is my first Ubuntu bug posting.
I did try manually setting the preferred-monitor parameter: gsettings set org.gnome.shell.extensions.dash-to-dock preferred- monitor 1 Then I verified the setting was changed: gsettings get org.gnome.shell.extensions.dash-to-dock preferred-monitor returned 1 However the dock continues displaying on all 3 monitors. I also tried setting monitor 2 and 3 but the same results. As the setting is changed all the 3 docks experience a brief flicker but all three docks remain. -- 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
