RandR

From Wikipedia, the free encyclopedia

The X Resize and Rotate Extension (RandR) allows clients to dynamically change X screens, so as to resize, rotate and reflect the root window of a screen. The initial X11 design did not anticipate the need for dynamic resizing and it was necessary to restart the X server to bring about the changes. RandR extension framework brought the ability to change display characteristics without restarting the X session. The extension framework allows laptops and handheld computers change their screen size to drive external monitors at different resolutions than their built in screens. ^[1] The current version of the protocol specification is 1.2.

If one's desktop environment doesn't provide a graphical tool for interfacing with this functionality, the xrandr command line tool may be used.
