Hi, The dock driver seems to work for me for undocking: when I press the button on my docking station, kernel prints a message and the button turns blank, telling me that I can get my laptop out. However, when I put my laptop back on the docking station, nothing seems to happen. Do I need to echo something on /proc or something else? Also, I'd really like to receive ACPI docking events in userland for triggering video devices configuration for instance.
