Supposed to? Sure! :) DP is finicky in general, and Maxwell is a
fairly new generation that not a lot of people have tested or had
access to, so quite expected for things to go wrong. Can you file a
bug at bugs.freedesktop.org xorg -> Driver/nouveau with the output of
nouveau loaded with
drm.debug=0xe nouveau.debug=debug,VBIOS=trace
Hopefully that will give an idea of what's happening.
