This is a T470s, and I started with only intel-backlight installed. I wanted to assign intel_backlight incr and decr to the brightness keys, but these are apparently not exposed to X. xev(1) sees the other xf86 keys (like volume), but not screen brightness.
So I put acpi_video_load="YES" in my loader.conf, and now I the brightness keys change the brightness.
But I have to press the key about 1000 times to effect any change. It's way too fine-grained.
I tried putting
in sysctl.conf as per acpi_video(4), but no change in granularity. With no example, I can't even tell the correct syntax (comma, space, equal, colon).
Any suggestions?
