I put together a new desktop using Zorin 16.1 Pro, with an GTX 690 graphics card. Ancient technology, I know. SLI is dead forever. Trying to make the best of it.
I'm having issues using each GPU to run a different monitor. I've been using the propriety Nvidia drivers that Zorin installs, trying to tweak things in X Server. I can get GPU0 to run two and GPU1 to run two, but if I plug one monitor into each, the monitor on GPU1 is black, maybe with a cursor if I'm lucky.
It's really odd, and I have no idea where to start. Randomly tweaking settings hasn't gotten me far.
