This means: Mouse, Keyboard can be plu= gged/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 t= he Ultra Dock Pro or something - the one that connects at the bottom of the l= aptop). >>=20 >> Also, in my setup wifi didn't work without adding iwm0 explicitly to clon= ed interfaces (which isn't something I wouldn't expect I have to do, but in t= his case I had to). >=20 > Did you have a > wlans_iwm0=3D"wlan0" > in /etc/rc.conf? =20 > I do not know or see why putting iwm0 in cloned would do much of anything > for a wlan device. >=20 > Also note that is wlans as in plural, not wlan_iwm0.

Without adding cloned_interfaces=3D"iwm0" wlan0 never shows up in ifconfig and wpa_supplicant never starts (that's cur= rent r326912, setup like described in my blog post). I just double checked to confirm the behavior. Best, Michael
