Best I can tell, this bug was fixed (for gnome-shell) in 18.04. The latest duplicates are from Ubuntu 17.10, and the above comments about later releases appear to be different bugs from this one.
If anyone finds a similar problem in Ubuntu 18.04 or later then please run this command to create a new bug: ubuntu-bug gnome-shell ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => Fix Released -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1292398 Title: Second screen position isn't saved from one session to another To manage notifications about this bug go to: https://bugs.launchpad.net/elementaryos/+bug/1292398/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
