#
# Automatically select a display configuration based on connected devives
#
# Stefan Tomanek <stefan.tomanek@wertarbyte.de>
#
# How to use:
#
# Save your current display configuration and setup with
# autorandr --save mobile
#
# Connect an additional display, configure your setup and save it
# autorand --save docked
#
# Now autorandr can detect which hardware setup is active:
# # autorandr
# mobile
# docked (detected)
#
# To automatically reload your setup, just append --change to the command line
#
# To manually load a profile, you can use the --load <profile> option.
#
# To prevent a profile from being loaded, place a script call "block" in its
# directory. The script is evaluated before the screen setup is inspected, and
# in case of it returning a value of 0 the profile is skipped. This can be used
# to query the status of a docking station you are about to leave.
#
# If no suitable profile can be identified, the current configuration is kept.
# To change this behaviour and switch to a fallback configuration, specify
# --default <profile>
#
# Another script called "postswitch "can be placed in the directory
# ~/.auto-disper as well as in all profile directories: The scripts are
# executed after a mode switch has taken place and can notify window managers
# or other applications about it.
