I'm still having the same issue with 13.10 -- my additional monitors are mirrored yet only detected as a single monitor. Is this planned to be fixed in any future version? With there being no support for DL-3x00 or DL-41xx (DisplayLink), it'd be nice to have the ability to run multiple external monitors on laptops with a single (mini-)DP port, as already possible on Windows.

I have my laptop (Lenovo ThinkPad X230, HD4000 Ivy Bridge) connected over mini-displayport to the display containing the hub, then the second display is plugged in that one over DisplayPort. DisplayPort 1.2 is enabled on the display containing the hub and the second display lights up fine but just works as a clone of the first display, without ever showing up in xrandr, dmesg or any other useful logs I could find. My understanding of MST is that the second display should show up as DP2 on my laptop so I can configure it as I would any other display.
