I just plugged in a 2nd monitor and it's working very nicely. I
have it
set so monitor #1 (primary) is on the right and monitor #2 (secondary)
is on the left. I set this from ALL SETTINGS -> DISPLAYS.
On reboot, the system comes up with #1 on the left and #2 on the right,
not physically, but virtually. I have to move the mouse to the right on
the primary monitor to get it on the secondary monitor to the left.
How can I force the settings to be saved across sessions and boots?
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.
From time to time, the mechanism fails, and the external display is
not powered up. I haven't yet figured out why this happens.
