[Thinkpad Series 3 docking station scripts] Thinkpad "docking scripts" for Series 3 docking station enabling or disabling both external displays on acpi events (https://www.kernel.org/doc/Documentation/laptops/thinkpad-acpi.txt). Only one pair of events should be used - check which ones (IBM/LENOVO/HKEY) acpid daemon receives. #thinkpad #linux #…
