Hi all,

I'm running linux mind and have downloaded ccminer and installed it to the best of my knowledge. My Nvidia information:

Stumbled upon the same error.

But I found a cause (the appropriate kernel module is not loaded by default by itself, Xserver by itself requires only the base "nvidia" module) and a solution.

To fix it, as a root, load the missing kernel module:

Code:

modprobe nvidia-uvm

After that, the miner runs.
