https://bugs.freedesktop.org/show_bug.cgi?id=109923 --- Comment #11 from Dima --- I've got the "--headless" installation working in Blender by installing of addition packages from amdgpu-pro 18.50 archive. The packages are libdrm-amdgpu-common, libdrm2-amdgpu, libdrm-amdgpu-amdgpu1. I used this tutorial to know what files are needed https://blog.cryptomilk.org/2018/03/02/using-amd-open-source-and-the-amdgpu-pro-opencl-driver-for-image-processing/. Now I have OpenCL in Blender and amdgpu open drivers working together. No any render artifacts and blackscreens. Thank you for the idea. -- You are receiving this mail because: You are the assignee for the bug.
