This is from the arch wiki[1], it seems the suggestion is to mask one of the services. On my system, intel_backlight is the only one active and it works well, so I suggest masking the samsung one with something like: systemd mask systemd-backlight@backlight\:samsung.service If that doesn't work, try the other way around, unmask samsung and mask intel_backlight.
