I'm up to setting up some mining rigs running Ubuntu. I use Nvidia GTX 970 and GTX 780 GPUs. I installed the 16.04 LTS server distro and it's working fine. I can tweak some GPU params using nvidia-smi. However, over- and underclocking can only be done with nvidia-settings utility which I have trouble running. The error msg is this:
Failed to connect to Mir: Failed to connect to server socket: No such file or directory. Unable to init server: Could not connect: Connection refused.
ERROR: The control display is undefined; please run nvidia-settings --help for usage information.
I looked thru internet a lot. Nvidia-settings needs graphic interface, so I installed Xorg, Ubuntu Desktop and everything I could find on the subject. The computer boots into graphic desktop now, however, nothing really happens after a login, the screen is pretty empty, no icon or anything. Nvidia-settings still not working.
I am accessing the computer via SSH, I created the xorg.conf file, I am using custom edid files to emulate monitors. I've also set coolbits to 31.
Maybe I should just install the full graphic version now, I am sort of clueless what to do next.
