Yep, removed those lines. As for the pigtail, I didn't switch from one to the other. The monitor on tail 1 works fine. I want to get the 2nd tail working for my other monitor. Or am I confused thinking that this card can support 2 monitors? The card is detected as a Quadro4 NV17GL 200/400. Do you need any other info?
For the pigtails, I was just assuming one is primary so if you only have one monitor, you should use that one. I may be wrong but I had an issue like that when I installed my one monitor. You are correct in assuming it can support two monitors.
Do you see any errors in the /var/log/Xorg.0.log file? Specifically look for lines that start with (EE).
I have the same kernel and gcc. I have a quadro NVS 280 and have recompiled drivers for the past two and a half years.
I don't know what else to tell you.
