are you sure your GPU has enough resources to handle a dual-monitor

I used to run a dual-monitor setup with a GeForce GTX950 2GB and had
exactly the same problems. Running OpenCL or CUDA on NVIDIA cards comes
with a lot of overhead, some desktop environments (looking at KDE and
GNOME) also need a lot of graphics memory, and in the end 2 GB were
usually not enough.
For whatever it's worth, I am also running darktable on a dual-monitor
setup with a GeForce GTX 750Ti 2GB and have no problems at all. Mind
you, I did tweak the darktablerc to increase opencl_memory_headroom to
500, so that may help David as well.
