P.S. AMDGPU-PRO 18.10 was just released and it works on Ubuntu 18.04, including OpenCL, provided the kernel is 4.13¹. RX Vega64 + darktable do the venerable bench.SRW in 2.5s. No issues with Xorg/KDE. 1. 4.13 can be installed from kernel.ubuntu.com/~kernel-ppa/mainline or by pinning linux-image-generic to 17.10 Artful (that way one gets updates too). -- Šarūnas Burdulis math.dartmouth.edu/~sarunas
