@fk2 let's see what we can do for each one:
NICE_NEOSCRYPT: KTccminer illegal instruction should solve if you recompile KTccminer, at least this is how I usually sove such kind of errors, let me know it this solves, I see you have got already its sources so if you compiled it already it is a problem
NICE_CRYPTONIGHT: default cryptonight miner is TPccminer, it does support the -i option as well but as I can see from the help the minimum valid value is 8, but nvOC has 0 by default in 1bash, please confirm me that setting intensity to somewhat valid solves the issue
*** ccminer 2.2.5 for nVidia GPUs by tpruvot@github ***
Built with the nVidia CUDA Toolkit 9.1 64-bits
Originally based on Christian Buchner and Christian H. project
Include some kernels from alexis78, djm34, djEzo, tsiv and krnlx.
Usage: ccminer [OPTIONS]
Options:
...
-i --intensity=N[,N] GPU intensity 8.0-25.0 (default: auto)
Decimals are allowed for fine tuning
NICE_ETHASH: somebody else already got this error, this happens with claymore on nicehash only, you have to set some extra arguments to mine ethahs on nicehash with claymore, see some posts above from @papampi. You should also have a tip for this in a comment near NICE_ETHASH_EXTENSION_ARGUMENTS in 1bash
nvOC restart: you can ignore that error about missing nvoc.service we will avoid this from showing up as well
miner not starting: both nvOC restart command and WTM switcher restarts nvOC the same way, so the problem is the same, let us know to which coin it is switching. The only log that can help you troubleshoot this is the gnome-terminal window when nvOC runs in gnome-terminal. Search for lines starting with "SCREEN ... miner ..". If the miner started but terminated immediately with errors you should be able to see it in nvOC miner-log command. You should see the previous miner output, then the same previously mentioned new miner command line starting with "SCREEN ...", then the new miner output/error. May not be related, but, what you have set in 1bash for "CONTROL_GPU_LED" ?
