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
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:
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.
