It doesn't look like https://gitlab.gnome.org/GNOME/mutter/issues/728.
It is about the hardware limitation that DELL DOCK - WD19 130W only supports two external Full HD at the same time. However mutter doesn't know the hardware limitation. I guest mutter will try to set up external Ultra HD and external Full HD that is over the hardware limitation of DELL DOCK - WD19 130W so it failed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1841886 Title: Join Displays failed when using two external monitor of one Full HD and one Ultra HD To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1841886/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
