Thanks. It appears the process of docking introduces three new DisplayPorts, of which two are plugged in.
To debug this further I do not know the commands. It might require a development setup, unless someone knows how to log udev events. I think that's what it will be... We'd like to know how many there are during docking, what type, and how far apart in time they are. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859955 Title: Long delays and repeated flashing when docking laptop with multiple monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1859955/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
