[Nouveau] xrandr HDMI-1 and DVI-D-1 disconnected - External monitor not detected

[Terje J. Hanssen]

Hi List,

I'm stuck how to get a dual head monitor solution to work with Nouveau, 
running openSUSE 13.1 on my hp8710w mobile workstation equipped with a 
Nvidia graphical card. Beyond the built-in WUXGA display, an external 
WQHD monitor is connected to the HDMI port on the graphical card and/or 
to the dual link DVI-D on a hp docking station.

To compare with SLED11/Nvidia driver running in dualboot with openSUSE 
13.1/Nouveau on the same workstation, the external monitor works up to 
1920x1080 over HDMI and at 2560x1440 resolution over the docking dual 
link DVI-D.


Here follows the query output using openSUSE 13.1/Nouveau/xrandr:


# lspci -nnk | grep VGA -A2

Beyond LVDS for the builtin display, all other graphical ports are 
reported as disconnected by xrandr:

# xrandr -q

DVI-D-1 disconnected (normal left inverted right x axis y axis)

I've tried a solution that has been suggested to add output to an 
external monitor, but it failed as shown:

# xrandr --addmode HDMI-1 1920x1080
# xrandr --output HDMI-1 --mode 1920x1080 --left-of LVDS-1
xrandr: Configure crtc 1 failed


I would be very thankful to get help here that can solve this confusing 
problem.
