Headless Ubuntu Bitcoin mining

mining - gcminer with ATIRADEON HD3600 on ubuntu 12.04 64bit headless won't detect GPU  October 23, 2013 – 12:27

I was myself unable to run completely headless. For some reason the ATI driver needs an XServer running.

Once you have an XServer running you still need to tell cgminer where to find it, setting the DISPLAY env variable takes care of this:

export DISPLAY=0.0 this though only takes care of the first ATI card. A little trick is not to specify the second part of the identifier:

export DISPLAY=0 this should let you at least find all the cards. Next you need to configure your XServer to make use of all present cards:

DISPLAY=0 aticonfig --initial --adapter=all -f Notice that prefixing commands with the env-variable setting works as well. Next you restart the XServer and test that it works:

DISPLAY=0 aticonfig --adapter=all --od-gt This should give you the temperatures for all cards you have installed. From there, you should be able to start cgminer and it should detect the cards:

DISPLAY=0 ./cgminer/cgminer -n
