http://serverfault.com – I have a system with 3 nvidia gtx 580s. I have a monitor connected via an onboard vga card and it's running xwindows with the intel driver. The nvidia driver does work as I run code on the 3 of them, and nvidia-smi shows up just fine. I'm running into overheating issues and want to force the GPU fans to run at a higher speed. Apparently, this requires using nvidia-settings via a gui which needs to be connected to the (headless) nvidia cards.
