After upgrading xf86-video-nouveau from 1.0.3-1 to 1.0.4-1, xrandr only sees one of two DVI connections.
Downgrading fixes it.

you should report this upstream after bisecting to find out which commit is the faulty one.
bisecting is pretty easy since there are a small changes between 1.0.3 and 1.0.4.

xf86-video-nouveau 1.0.4-1 works with xorg-server 1.13.0-3, not with xorg-server 1.13.0-4.

According to people in #nouveau on Freenode, it may be the file git-fixes.patch in xorg-server 1.13.0-4 and especially lines 437f:

+ if (ServerIsNotSeat0())
+ break;

I just built xorg-server 1.13.0-4 with those two lines commented out and it works.

Running pixman 0.28.0-1, since that seems to matter, too.

This is apparently fixed in 1.13.0.902-2.
