    So... Linux documentation needs a bit of help, and I may have a bug.

    1) On Ubuntu, and perhaps others, you need to force the shared library. (LD_LIBRARY_PATH=. ./cgminer --blake256 --benchmark)
    2) You need open cl installed and accessible. It is driver version specific. Check with; (ldconfig -p |grep libnvidia-opencl)
    3) Another dependency is libssh2. (On Ubuntu 14.04.3 libssh2-1)

    4) Headless operation is NOT working.
    Code:
    lee@dev01:~/Downloads/cgminer-decred-linux-x86_64-20160127-v3$ LD_LIBRARY_PATH=. ./cgminer --blake256 --benchmark
    Error opening terminal: xterm.
    
    This is with ssh with x tunnelling enabled, however "gedit" also does not work, so it may be this crappy VPN I am on. (xeyes did, and xterm comes up after significant delay so the tunnel is up) But I do not think a hard dependency on x tunnelling from a headless server is a good idea. I will try again tomorrow night when I get back home.

    Just a guess but adding TERM=screen might help.

    I'll spin up a Ubuntu VM and see what I can do to make it run reliably, sorry for the inconvenience.

    @jolan, I can try to help with Ubuntu, don't worry.
    On a similar note, I'd love to be able to help by providing binary builds for Ubuntu and / or Fedora in the future

    Statically link the thing - the OpenCL stuff uses the ICD on the system anyways.

    As I suspected, the code can get better - but on GCN cards, not much faster. Well, not using traditional methods. Time to try a new tack - but I'll need to modify cgminer itself to do so.

    Guys what version of ccminer are you using to test speed on nvidia cards?

    They're probably using cgminer.

    Thanks Wolf. cgminer works just fine. but seems like 750Ti not so fast.
    485mh\s.
    i hope there will be improved ccminer version...

    OK testing mining with cgminer, only getting less than 50% of hashrate that i get on ccminer for 14 round blake. Good to test but not so good for mainnet. I hope we see modified ccminer for decred before that. Maybe @Wolf can help with that too.
    GTX970 hashes at 1.05GH/s
    GTX750ti hashes at 405MH/s

    EDIT: ok managed to improve hashrate to

    GTX970 hashes at 1.11GH/s
    GTX750ti hashes at 431MH/s

    by setting intensity to 10 on both cards. It took me 47 mins to find a block and 22 mins for second. Lets see if i get the balance after 16 confs.
