Default Re: nvclock: map_dev_mem (mmap) returning -1

Nvclock uses /dev/nvidia0 when it is available. The file is created when you load the nvidia kernel module but it is only activated when you enter X. If you don't have X running you could get this behavior. Nvclock can also use /dev/mem in such a case but that requires root ..
