Allow disabling non-primary monitors via Super + P
Feature summary
The Super + P should allow the user to disable non-primary monitors, like it is done in Windows 10.
Currently, no option presented in the menu which is shown by pressing Super + P allows this, instead it just discards the current display configuration (monitor scale/position/rotation) when any option is chosen.
An example would be selecting Join Displays
: After I selected it, my display configuration was completely reset and afaik this should be a no-op, as that was the configuration which was already enabled at that time. But regardless of which option was chosen, the scale/position/rotation should be left unchanged. This is probably a good fit for a bug ticket, though.
I think this would be a good addition, as this would allow conserving power when a user is for example watching a video/playing a game for an extended time and doesn't need the other monitors.
How would you like it to work
There should be an option called Primary Monitor only
in the Super + P menu, which disables all non-primary monitors. If possible, these disabled monitors should be completely disabled, so that they are not part of the display layout anymore.
Switching back to Join Displays
/or the previous option in general should restore the old display configuration.
