The Display Arrangement is changed after changing the Display Mode
(single display, mirror, join displays).

I have a notebook connected to an external display which is physically
placed on the right side of the notebook and which I typically is as my
primary display.

The default seems to be that the primary display is the notebook ones on
the left and the joined external on the right. In the Gnome display
settings I can change both to make the external display the primary one
and move it to the right. So far all perfect.

However I often disable my notebook display. Typically using the
%SUPER%-P shortcut but also using the Gnome display settings.
Unfortunately when I switch back to joined displays the placement gets
messed up. While it is remembered that my external was chosen as the
primary one (opposed to the default) the placement gets reset and the
primary display is assumed to be on the right despite having it arranged
it the Gnome Display settings to the right before. As a result I have to
re-arrange it manually using the Gnome Display settings every time I
switch back to joined displays.

Is there anyway to make Ubuntu/Gnome/Xorg remember the display
arrangement? Or as a workaround switch the arrangement with another
shortcut?

P.S. I'm using Xorg and NVIDIA 390.25 drivers from the graphics PPA in
case that's important in any way.
