One Ouput of My Nvidia Card Stopped Working

I was using the nvidia driver until last week when it stopped working, mysteriously. I posted about that over here. Anyhow I switched to nouvea and I have X back. But now only one output of my Nvidia card works. Here is what I see:

[kirk@arch ~]$ lspci | grep -i  'vga'
01:00.0 VGA compatible controller: NVIDIA Corporation G98 [GeForce 8400 GS Rev. 2] (rev a1)
[kirk@arch ~]$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
DVI-I-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 290mm
   1920x1080     60.00*+
   1680x1050     59.95  
   1280x1024     75.02    60.02  
   1152x864      75.00  
   1024x768      75.08    60.00  
   800x600       75.00    60.32  
   640x480       75.00    60.00  
   720x400       70.08  
DVI-I-2 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 290mm
   1920x1080     60.00*+
   1680x1050     59.95  
   1280x1024     75.02    60.02  
   1152x864      75.00  
   1024x768      75.08    60.00  
   800x600       75.00    60.32  
   640x480       75.00    60.00  
   720x400       70.08  

but only one screen works. I switched the screens to test them and both screens work fine--it's the card output not working. If I play with xrandr, it recognizes if I put the screens side by side because the xfce4-panel goes across both screens--I can tell because the icons on the right side disappear.

But the second screen (non-primary) never shows anything.

I suppose it could be that the card just broke (or the DVI to VGA adaptor) but it seems too coincidental that it broke precisely when I switched to nouveau.

Any suggestions how to further debug this? I will try again to see if nvidia will magically just work now, but I am not counting on that.

Re: One Ouput of My Nvidia Card Stopped Working

nvidia still fails for me. Seems the problem here is the card (or adaptor) are broken but when I unplug the second monitor I see

$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
DVI-I-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 290mm
   1920x1080     60.00*+
   1680x1050     59.95  
   1280x1024     75.02    60.02  
   1152x864      75.00  
   1024x768      75.08    60.00  
   800x600       75.00    60.32  
   640x480       75.00    60.00  
   720x400       70.08  
DVI-I-2 disconnected 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

So at least it detects correctly. If I leave in just the adaptor with no monitor, I still get "DVI-I-2 disconnected" output.

Nothing shows up still on the second monitor however.
