switch_screen is a C tool to switch monitor input with DCC commands.
Requires dccutil
The typical use case is to map a keyboard shortcut to switch_screen. It really just calls dccutil, but using switch_screen there is no need for sudo.
Makefile could use some work.
Requires dccutil
sudo apt install dccutilthen
makeswitch_screen <input>input can be 1-5.
switch_screen_# are just hardcoded versions.
Meets me needs so I don't bother updating it. Feel free to fork or raise a PR.
