--- Comment #8 from Flo Bock (flo@dontshoot.at) --- With recent systemd changes, the 16 bit values in actual_brightness break saving and restoring the backlight values using AMDGPU. According to a closed issue on Github, Lennart Poettering sees this as a kernel issue[1]. Is there any good reason for actual_brightness to be 16bit, whereas both max_brightness and brightness are 8bit?
