This means: Mouse, Keyboard can be plugg= ed/unplugged as many time as I want at any point, while displays connected o= ver display port only work when connected before starting X (and they don't d= isappear 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 U= ltra Dock Pro or something - the one that connects at the bottom of the lapt= op). Also, in my setup wifi didn't work without adding iwm0 explicitly to cloned i= nterfaces (which isn't something I wouldn't expect I have to do, but in this= case I had to). -m
