Re: nvclock: map_dev_mem (mmap) returning -1
Note that I don't support all fanspeed methods in nvclock. If it is supported on Windows I can offer it in nvclock as long as I know what register to modify. Wait a second you are using an SLI system. In that case for some reason /dev/nvidia1 is the primary card. When SLI is disabled /dev/nvidia0 is not active. I don't support this properly yet in the code.
