NAME
xrandr - primitive command line interface to RandR extension
SYNOPSIS
xrandr [-help] [-display display] [-o orientation] [-q] [-v] [-s size] [-x] [-y] [--screen snum] [--verbose]
DESCRIPTION
Xrandr is used to set the screen size, orientation and/or reflection. The -s option is a small integer index used to specify which size the screen should be set to. To find out what sizes are available, use the -q option, which reports the sizes available, the current rotation, and the possible rotations and reflections. The default size is the first size specified in the list. The -o option is used to specify the orientation of the screen, and can be one of "normal inverted left right 0 1 2 3".
The -x option instructs the server to reflect the screen on the X axis. The -y option instructs the server to reflect the screen on the Y axis. Reflection is applied after rotation.
The -help option prints out a usage summary. The --verbose option tells you what xrandr is doing, selects for events, and tells you when events are received to enable debugging.
