GTX1070 OpenCL not detected, Failed to open... libOpenCL.so

I have just bought an old Gigbyte GTX1070 for folding but it just sits idle. I have two PCs and I put it in the old one, FX-8350 CPU, as the new one (Ryzen 2600 CPU) gets about 65K ppd. I am using Linux Mint Mate 19.3 64-bit. Using nVidia's own drivers from the Mint drivers utility. Usually connected with HDMI to an old TV. Connecting to a DVI monitor instead made no difference. I re-installed Fahclient.
The card has an RGB sign "fan stop" and this is on, indicating the fans are off. I have done some searching on the web and bit-tech but found postings from years ago.

The pinned post, "How to get the most Folding Points from your Hardware" is from 2009 to 2014. Does anyone else think a new thread is in order?

** Update ** I have installed Windows 10 Home. The 1070 works perfectly on Windows on both computers.It works with both the old HDMI TV and the DVI monitor.
It would be nice to have it work on Linux, though, as I dislike Windows Update.

 

Have a look here, see if it helps:
