I mean it's easy to set a load and watch for stability problems. I got my curve just right for every load I could throw at it from 1 - 16 cores, but I could never get the idle states where I wanted them.

When using only the discrete graphics card the brightness control works perfectly. It is worthy to note that the value of /sys/class/backlight/amdgpu_bl0/actual_brightness is stuck at 311 and does not change at all. Now try to change the brightness with software, Fn keys and changing /sys/class/backlight/amdgpu_bl0/brightness and the brightness will not change, i.e The brightness control will not respond and the brightness will always be at max. By default the panel uses iGPU for everything and offloads large graphical apps to dGPU. Now you should have AMD iGPU and NVIDIA dGPU enabled.
