This package helps you control your GNU/Linux desktop from Emacs. With desktop-environment, you can control the brightness and volume as well as take screenshots and lock your screen. The package depends on the availability of shell commands to do the hard work for us. These commands can be changed by customizing the appropriate variables. The global minor mode `desktop-environment-mode' binds standard keys to provided commands: e.g., to raise the volume, to take a screenshot, and to lock the screen.
