My experience with GNOME is that it is generally saved across
sessions.  I have a file ~/.config/monitors.xml which lists the two
different setups I use regularly (two separate workplaces with
different external monitors), and GNOME Shell (or something else)
automatically applies the proper settings.  I suspect it needs correct
EDID data for this to work, though.

not powered up.  I haven't yet figured out why this happens.
