Xrandr Graphical Front End GUI
ARandR is designed to provide a simple visual front end for XRandR.
Relative monitor positions are shown graphically and can be changed in a drag-and-drop way.
LXRandR is the standard screen manager of LXDE. It manages screen resolution and external monitors.
You can plug in another screen into LXDE or choose to use a big screen projector.
Local screen and extenal screen can be used at the same time. LXRandR configures the screen solution automatically.
