Description Massis Sirapian 2008-11-01 03:46:43 UTC 
Hi,

I have a NV11 with two DFP monitors connected : one via a VGA connection (main screen), the second, via its DVI input to the DVI output of NV11. With nouveau, only VGA-0 is seen.

Both are connected at boot. Under Windows, they work and are recognized. With nvidia blob, it used to work until lately, as their legacy driver is broken for the dvi output of NV11 (and they won't fix it, naturally).

So the symptom is simple : only vga monitor is seen.

sirapian@enigma:~$ xrandr -q
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2704 x 1050
VGA-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 307mm x 230mm

I've read the xorg.log, it seems to see 4 DCB entries, which are merged to one, and only VGA monitor is seen. In a former xorg.log, when I used the blob, it saw there 2 DCBs, and the two monitors were identified.

I attached my xorg.0.log. 

I'm using the experimental debian packages (the latest ones). 

If you need further information or investigation, please tell me.

I'm interested to hear of the nvidia log listing DCB entries. Could you attach a xorg.log from the nvidia driver showing this output?

I've looked for that old xorg.conf, but I'm unable to find it (probably a xorg.0.log.old which has been erased now).

So I've reinstalled the blob to produce a xorg.0.log with -logverbose 6. Doesn't show these DCB entries, but still, both monitors are detected.

I attach that xorg.0.log obtained with the blob, if it helps.

xorg.0.log obtained with last blob driver + logverbose level 6.

DVI now works on my NV11 card, so you might like to try testing again.

No reponse from the reporter for more than a year. Closing.
If the problem still exists on current version, please reopen with new set of logs.
