X11 bindings for ruby
Lightweight object wrappers around a subset of Xlib to handle displays, screens and windows. Uses Xrandr to deal with multi-monitor setups.
Installation
gem install xlib-objects
Basic usage
require 'xlib-objects'
display = XlibObj::Display.new(':0')
main_screen = display.screens.first
root_win = main_screen.root_window
root_win.width # => e.g. 3600
root_win.height # => e.g. 1080
outputs = main_screen.crtcs.map(&:outputs).flatten
outputs.first.name # => e.g. 'DVI-I-1'
outputs.last.name # => e.g. 'DVI-I-2'
