I’m relatively new to Linux but plan on running my old xeon machine with a Radeon rx 580 on Ubuntu, switching from win 7 64 (because I hate it). I already have a partition with Manjaro Linux running, but all in all this distro is not all too user friendly for say to say work and not as widely supported for Blender work, so I parallel installed Ubuntu 18.04.2 LTS last week.
As I knew from Manjaro, for gpu rendering one needs the Amd GPU pro driver with open CL running. So I installed the latest version from amd website. I think it’s 16.50 or so. Blender 2.8 recognizes the CL in prefs and I can select both CPU and GPU. But when I switch to render preview, the whole system freezes, leaving only the cursor movable and not even the keyboard reacts to input. Whe I uninstalled the amd gpu driver, I thought that Mesa would jump in again, but without that driver, the gui didn’t load and I had to reinstall it via command line.
Is there some kind of best practice for an AMD GPU setup on Ubuntu? Or what have I done wrong? Or is there even a properly working Mesa solution with open CL? I didn’t find anything.
I appreciate any help!
