I've installed Juno release and all it's amazing, except that when I block my notebook, that have a secondary display, the display settings is lost.
My notebook is on the left side and my main screen is his, the secondary screen is on the right side. When the compute is locked, the login screen is showed on my secondary display, instead of the notebook screen (my main display). The position of screens is lost too, like my notebook is on the right and secondary monitor (now primary) is on the left
