--- Comment #2 from Van (kernvirt at gmail.com) ---
Update 2: I'm tested Ubuntu 25.04 with kernel 6.14, amdgpu_bl1, and brightness
works the same as on Debian with 6.12 lts, But for some reason on Fedora and
Arch with kernels 6.14 and 6.15.5 the brightness is non-linear, as I said
earlier, That is, the meaning of brightness does not match with the meaning of
actual brightness.
