In my setup, plug/unplug events for display port don't work when docking (usually I'm not using a dock though). This means: Mouse, Keyboard can be plugged/unplugged as many time as I want at any point, while displays connected over display port only work when connected before starting X (and they don't disappear after disconnecting). Note that stopping X seems to fix this (so no reboot required), but I don't have the docking station myself (this is the Ultra Dock Pro or something - the one that connects at the bottom of the laptop).

Also, in my setup wifi didn't work without adding iwm0 explicitly to cloned interfaces (which isn't something I wouldn't expect I have to do, but in this case I had to).
