# How to use:
#
-# Save your current display configuration and setup with
-# autorandr --save mobile
+# Save your current display configuration and setup with:
+# $ autorandr --save mobile
#
-# Connect an additional display, configure your setup and save it
-# autorand --save docked
+# Connect an additional display, configure your setup and save it:
+# $ autorandr --save docked
#
# Now autorandr can detect which hardware setup is active:
-# # autorandr
-# mobile
-# docked (detected)
+# $ 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.
#
+# autorandr tries to avoid reloading an identical configuration. To force the
+# (re)configuration, apply --force.
+#
# 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
# --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.
+# ~/.autorandr as well as in all profile directories: The scripts are executed

+#
+#
+# While the script uses xrandr by default, calling it by the name "autodisper"
+# or "auto-disper" forces it to use the "disper" utility, which is useful for
+# controlling nvidia chipsets. The formats for fingerprinting the current setup
+# and saving/loading the current configuration are adjusted accordingly.
