No, it works undocked. When docked, the external screen doesn't show any
picture, but X seems happy with it (not me!), so that I assume it shows
something on the internal (closed) LCD.
But I can try the option.

Eerg, you mean patching, recompiling, etc... ? Hmpf, need to think about
it, especially where you complain in there about regression issues :->

Sounds like the bug you pointed me to is the potential solution to the
issue, no? (I'm referring to: "- LVDS + internal TMDS. if you have a
laptop or docking station with LVDS and a DVI port, ...")
I'll have anyway a deeper look at the entry.
