We (TUXEDO Computers) are selling laptops and PCs with openSUSE Leap preinstalled. One problem we run into quite often is the relatively old kernel version of Leap. E.g. for our lines of AMD Renoir laptops we would need at least 5.6.x upwards to get everything running. Are you sure neither 15.2 nor upcoming 15.3 kernel support your hardware? We have a lot of hardware enablement in these, both for CPU and GPU.
Yes, kinda. The machines boot and work but there are two major issues with AMD Renoir graphics: 1) Brightness control does not work. The Fn keys for brightness up/down trigger the video port feature from Plasma. Plus it gets triggered on it's own from time to time. Devs told me it's related to this commit: https://github.com/torvalds/linux/commit/14ed1c908a7a623cc0cbf0203f8201d1b7d... 2) On machines running kernel 5.6+ glxinfo shows AMDGPU as renderer while on Leap 15.2 stock kernel there's only OpenGL listed as renderer. This leads to a significant performance loss as the hardware capabilities don't get used. First tests with Intel Tiger Lake (11th Gen) show the same symptoms. This in the end would mean we can't ship stock Leap 15.2 anymore. Which I would wan't to avoid if possible. vinz.
