Does your machine have an internet connection?
I'm pretty much a noob in Linux... But would creating a bootable USB stick with Ubuntu work out of the box? i.e. would it be just as easy as that downloading the miner onto it and hash away?
Ubuntu will not work right out of the box since it won't have drivers. HiveOS will have amdgpu-pro drivers for Polaris GPUs out of the box. For Vega you're best off installing Ubuntu and then installing drivers from the ROCm 1.7 repos.
My rigs requires the generation 2 setting and I hope this version is compatible.
Polaris with amdgpu-pro drivers will work with gen2 pcie. Vega on ROCm will not work on gen2 pcie (requires gen3).
