Running cuda in xmr-stak on Endeavouros

It’s technical more than anything, i’ve asked you specific questions above, start by answering them…

P.S. but if you want to just mine XMR on your home PC - my advice is to use xmrrig, because unless you have an AMD EPYC or something, it’s not about money, but about supporting Monero infrastructure, for almost 0 profit on your side - which is very noble.
