I use a different approach which is more flexible (unless I've missed
something about xrandr) but I restart the Xserver when I'm changing
the setup (*to* two screens, but not when reverting to one). I don't
use a Desktop Environment.
I use bash functions to clear and then copy the appropriate set of
files to /etc/X11/xorg.conf.d/ from this selection (basically one of
each number):

As it happens, I use the laptop to the left in each case, so my
Position option is always in the HDMI monitor and positive. You
would either want to insert a minus sign, or move the option to
the other Monitor section to reverse things; either method works.
Why don't I do all this on the fly? Mainly because my .xsession
looks at the resolution and starts up all my (~20) xterms with
font sizes, geometries and positions as appropriate, and also
writes some little helper files for fvwm to be able to move
particular windows back to their "reset" positions automatically
on command (clocks, players, controls etc).
Cheers,
David.
