Attempt 2007 01 28

The output is activated, but nothing appears on the screen. This is with DVI-A-1 at boot.
Comment 1 Adam Petaccia 2008-01-28 09:53:42 UTC 
Correction: This is with DVI-A-0 at boot, but DVI-A-1.

DVI-D-1 plugged in at boot

If DVI-D-1 is connected at boot time, it works.
Comment 3 Maarten Maathuis 2008-01-29 10:13:22 UTC 
Please run nouveau (for both cases) with NOUVEAU_MODESET_TRACE in nv_local.h enabled.

DVI-D-1 plugged in at boot with MODESET_TRACE

Hope this helps.
Comment 6 Maarten Maathuis 2008-02-01 10:36:18 UTC 
Come by irc sometime, maybe we can isolate the bug even further.
Comment 7 Adam Petaccia 2008-02-02 08:44:14 UTC 
After an old hack for 7x00s was removed, I no longer experience this problem.  I can hotplug anything with anything booted (not counting actually swapping connections).
Comment 8 Maarten Maathuis 2008-02-02 10:03:20 UTC 
Cab you disable DVI-D-0 and then try to move around DVI-D-1?

(xrandr --output DVI-D-1 --mode <insert> --crtc 0)

Purely for my curiosity ;-)
Comment 9 Maarten Maathuis 2008-02-02 10:16:37 UTC 
I meant disable DVI-A-0.
