Hi,
when both displays are enabled I set the monitor (connected to the display
port) as primary and the LG TV (connected to the HDMI port) as secondary.

# in both cases the output of xrand does not change:

DP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis)
476mm x 268mm

1600mm x 900mm

...
When both monitors are enabled:
- If I click "Extend to the Right" from Display Configuration, even though the
main monitor remains primary, it actually becomes secondary, and the mouse
moves over the left edge of the TV (and not to the right as it should).
- Furthermore, to return to the primary monitor from Display Configuration, I
have to click "Switch to External Monitor" (first icon), otherwise, if I click
"Switch to Laptop Screen" (second icon), the signal goes to the TV, even if
it's off. To go back, I either turn on the TV and switch from there, or I have
to use the META+F1 macro to call Display Configuration and blindly move around
with the keyboard to restore (because even if I reboot, this setting remains
and there's no way to undo it).
It would be helpful to be able to assign shortcuts to the Display Settings
icons; it would make things easier.
