Once I got opencl installed and rebooted the machine, I was able to start Resolve and get into the main interface. It couldn't find a GPU though ("clinfo" showed one), I'm guessing that it really,truly does need an nVidia card. I brought home a card from work to try, just to see if it would make a difference, but someone put a AMD card into the box of a nVidia card.
I tried Resolve on my wife's Win10 laptop with Intel GPU, and it seemed to install and work no problem. Since I'm basically going to be using the machine for just editing when I'm editing, I may just set it up with Windows and call it done.
From some of the introductions I've watched, it looks like Resolve is the software I want. Lightworks has worked well, but Resolve looks like a space age rocket ship. I guess we will see...
