#
# 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
-# configuration, apply --force.
+# (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
# --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.

+# While the script uses xrandr by defult, 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.

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
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>
+ --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
+ ~/.autorandr as well as in any profile directories: The scripts are executed
+ after a mode switch has taken place and can notify window managers.
+
+ When called by the name "autodisper" or "auto-disper", the script uses "disper"
