Ciao,
is your system composed by two graphics card?
I spent several hours struggling against a NVIDIA + Intel setup, in the
end I won via bumblebee (browse the net for it). Idea is that Intel asks
to Nvidia to process data, and then displays the result.
Let's suppose that your Intel card doesn't support open cl, you suppose
to start darktable via Nvidia, but running Intel instead. It would
explain why it runs only if opencl is not present...
Good luck, and enjoy this fabolous piece of software we're speaking about.

Hi,
google indicates that the error message "X server found. dri2
connection
failed!" meight be linked to beignet, the OpenCL implementation for
Intel graphics cards.
+1, it most definitely is.
There was a person with "X server found. dri2 connection failed!" problem
on #darktable just a few days ago, and exterminating beignet from his
system
has solved the issue for him.
As you said you have just bought a new Nvidida
card. Maybe there are stale libraries and/or config files of your
previous hardware setup in the way.
Best wishes
Ulrich
Roman.
