I have problem with lowering backlight on my laptop. Keybind won't work. Volume lowering and rising is working as expected.
I have another problem. I can't mount any partition.
I have Xfce no multilib / llvm profile.
I have old Gentoo installation, it is not fresh install.

I have tried gentoo-kernel-bin along with my custom kernel, no changes.
I can manually change brightness via terminal, so that is working.
Revert last backup from one month ago.
Updated.
Still I have the same problem.
