Tool: "autorandr"

Automatically select a display configuration based on connected devices

How to use:

Save your current display configuration and setup with:

$ autorandr --save mobile

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)

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

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

~/.autorandr 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 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.
