# This script aims to be fully compatible with the original autorandr.
#
To change this behaviour and switch to a fallback configuration, specify
--default <profile>.
- Another script called "postswitch "can be placed in the directory
- ~/.autorandr as well as in any profile directories: The scripts are executed
- after a mode switch has taken place and can notify window managers.
