beamer
is a simple command line tool for toggling and positioning a secondary monitor or projector on Linux.
It is a thin wrapper for xrandr
to spare you typing out common setups in its verbose syntax. Consequently, it requires xrandr
to be installed on your system.
Commands
Commands assume the first output listed by xrandr
to be the main output (e.g. a laptops monitor).
