Hello Andy, Many thanks for the feedback. I've already sent this to nVidia and to the good folks at nvnews.net, along with the output from nvidia-bug-report.sh. A friendly fellow with the handle of Netllama has already gotten back to us with a few suggestions, which we will be trying this evening. I will also make use of your suggestion, but I have a follow-up question: what exactly do you mean by "one X screen" on each GPU? You don't mean it will only drive one of the *monitors*, right? Are we talking about each GPU driving a pair of merged monitors with nView, but the two "paired sets" of screens will be clones? That is, monitors A & B are on a splitter driven by GPU 1, C & D on GPU 2; A & B will be merged as "one X screen", C & D will be "one X screen", but then what about A&B + C&D? Clones? Merged? Will I need to use Xinerama for that? If so, what sort of problems come up with that? I may be reading too much into what you're saying; I'll wait to hear your reply.
