I'm having a very weird issue... My rig has 3 RX 480 and it seems unstable as soon as I install the driver. I've tested all OS (windows 8 32 bits, 8.1 64 bits, Windows 10, Ubuntu server) and I'm now on an Ubuntu Desktop LTS 16.04.
I managed to install the AMD drivers but lost the X11 interface so I'm connected using SSH.
As I'm a big noob I've struggled for days to get ethminer installed and it's now setup from apt-get (couldn't get the git version to work).
ethminer runs well (but no hashrate) but when I type -G I have the following error:
~/Downloads/cpp-ethereum/build$ ethminer -G Segmentation fault
But when typing ethminer -F $URL I have the following issue:
miner 10:47:27.154|ethminer Getting work package... ✘ 10:47:27.307|ethminer Failed to submit hashrate. ✘ 10:47:27.307|ethminer Dynamic exception type: jsonrpc::JsonRpcException std::exception::what: Exception -32003 : Client connector error: libcurl error: 52 JSON-RPC problem. Probably couldn't connect. Retrying in 1...
I'm totally stuck and have exhausted all my options, can you please help? Just for information, I don't have the blockchain locally as I'm trying to mine from a pool.
Many thanks in advance,
