Running ubuntu 16.04. Installed the nheqminer\_AMD miner following all the instructions at [GitHub - nicehash/nheqminer: Equihash miner for NiceHash](https://github.com/nicehash/nheqminer).

I can mine with just one GPU no problem. Can switch between them. But when I attempt to mine with two, it crashes. Using the command:

./nheqminer\_AMD -l zec.suprnova.cc:2142 -u NAME.worker\_1 -p XXXX -t 0 -od 0 1

I also tried:

./nheqminer\_AMD -l zec.suprnova.cc:2142 -u NAME.worker\_1 -p XXXX -t 0 -od 1 0  
And  
./nheqminer\_AMD -l zec.suprnova.cc:2142 -u NAME.worker\_1 -p XXXX -t 0 -cd 0 1

I can only get one card to mine if i drop the 1 or the 0 and just have one card listed.

Anyone else running into this problem?
