Notably, there is no /sys/devices/platform/dock.0 As a result, it seems that no kernel event is fired on (un)docking, thus making it quite difficult to automatically adjust monitor/display settings accordingly. I am really using the TuxOnIce variant of the mentioned kernel version, but the problem occurs in the official version as well. Ubuntu was installed on this laptop while it was not plugged to the dock, using the Alternate (text based) installer.
