Does anyone know how to control the nvidia fan when using this driver? Its the only thing I am not able to figure out and my video card starts getting really hot after a bit. I have tried sensors and it does not detect anything(fan related). I also did the pci prog, cant remember the name off hand not on my arch box right now. I know the CPU fans are GPIO fans, does that mean the nvidia one is as well and I can not control it? Keeping it on a cooling pad keeps things cool enough, but I would really prefer to keep using this driver for the time being with all the Xorg issues with the proprietary drivers, and I honestly think the nouveau ones are worse than the proprietary, NV has never let me down minus the heat issue on this one laptop.
Card: GeForce 360m
Thanks for your time
It seems likely that your card's power management features aren't supported by the -nv driver, NVIDIA dropped support for that in 2010 and no longer support the open source efforts. At the moment of dropping, the -nv drivers lacked proper randr, KMS and powersave support. I would say that you're simply running into the limitations of a somewhat outdated driver. Nouveau is slowly catching up and is supporting powersave features for newer models, but it's touch and go. You card is of the NV50 family, nouveau's PowerManagement feature Wiki[1] mentions support for frequency scaling to be "MOSTLY" done and fan speed to be "WIP".
