I heard something...
For those of you running Linux GPU rigs, what are you using as mining software? I'm using SimpleMining so my choices are restricted to:

XMR-AMD-STAK: This throws errors when I try to connect it to Mine77, something about invalid difficulty target.
Claymore 9.1: Refuses to mine anything that's not on its list of coins (XMR etc) which is too bad as it's the quickest for Cryptonite. No update for Linux, won't take the allcoins parameter.
SG-Miner: Works, not as quick as either of the others, seems to restart several times every hour.

Really wish there was a workaround for Claymore.
