Cryptonight + Eth won't work
Hi!

First off; awesome work!

I'm having an issue with 2.2.2.

1) If I set eth/ethash in the list of algo's eth is never used.
2) I can't mine crypto on my 1080ti because of the following message:

However with the mininghub 1.7.3 repo; it works just fine.

My system is as follows:
Xeon 3690
24 GB RAM
1080Ti
950 GTX
96GB of virtual memory set as a minimum.

Is there anything more I can provide to fix this?

Thanks!
