 # xrandr
 
+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.
