Small utility to handle docking and undocking of ThinkPad laptops running Linux. Tested with an x200s running Arch and an original Lenovo docking station hooked to a VGA FullHD monitor.

These instructions will get you a copy of the project up and running on your local machine. It is heavily reliant on my personal setup so you might need to adapt paths and names for your environment.

What things you need to install the software and how to install them:

• ThinkPad laptop
• Docking station
• Monitor
• Linux distro
• xrandr installed
• udev installed

Run the included scrit to install the utility

./install.sh

It will install two components with sudo, for which you will be asked for your password:

• udev rule to /etc/udev/rules.d/

• Global script to /usr/local/sbin

And two components for your user, under ~/.config/dock/ and ~/local/bin/. It assumes that ~/local/bin is in your path. If not, adapt the install script according to your setup.

The utility is composed of 4 parts: udev rules, a global script, trigger scripts and user scripts

The udev rules simply call the global script every time the dock kernel component changes

The global /usr/local/sbin/thinkpad-dock.sh script checks the docks status and calls the trigger scripts for any logged-in user.

The trigger scripts live under ~/.config/dock/[on|off]. They perform some basic checks to make sure the docking process is finished before calling the user scripts

The user scripts should be called dock and undock and be callable from the shell. This allows call them manually, for instance after boot while docked does not call the udev rule.

The default behavior of the scripts is to turn the VGA output on/off and ajust the conky configuration file according to the docking status.
