Dual GPU & OPenCL/Mesa Issues

[DrRobotnik]

Thanks for the advice. Wasnt aware that hashcat via the The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) repo would be the cause.

Have reinstalled hashcat from source on Mint, and am no longer seeing the previous errors with OpenCL/Mesa.

However, still only one GPU is being utilized (the below is a test cap to confirm both GPUs are working together):

Code:

hashcat (v3.30) starting...

i know that both GPUs work independantly, and can benchmark both GPUs together, so dont think theres an issue with hardware, but have been wrong several times before with this process.

Any advice?
