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