Blender GPU Support on Linux with AMD Radeon Pro WX 7100 Mobile I have a Dell Precision 7740 running on Ubuntu 18.04 Linux with an AMD/ATI Radeon Pro WX 7100 graphics card and a much less powerful Intel UHD Graphics 630 (Mobile). I'd like to utilize the graphics card to help speed up Blender renders. However, under the "System > Cycles Render Devices" setting, I see a "No compatible GPUS found for path tracking. Cycles will render on the CPU."

Given this card and os, what options do I have to optimize my renders and take full advantage of the GPU? 

I've encountered the https://www.amd.com/en/technologies/radeon-prorender-blender project. Is this a viable option? (Though I imagine it would be a different rendering engine to learn apart from Cycles and Eevee).

Any thoughts are much appreciated. Thank you

Updated: Added a picture
By the looks of the lspci you're using the non pro AMD driver which is required for OpenCL at the moment.

The pro driver is available going to AMDs website and searching for drivers for your card. There is a download link for Ubuntu but the latest version they support is Ubuntu 18.04 (x86_64). You might also find you have to use a slightly older kernel version too.

Hopefully at somepoint we will get OpenCL support from the kernel amdgpu driver.
