Since around 2022-11, I am unable to change display brightness
of the display of a Framework laptop (Intel i5-1135G7, Iris
Xe iGPU) with "i915kms" module (from "drm-510-kmod" package/port)
& "acpi_video" (FreeBSD) kernel module.

Earlier I was able to change brightness via "hw.acpi.video" MIB ...

# - Need to have both "i915kms" & "acpi_video" modules already loaded.
#
# 20221120 - These MIBs do not work anymore as they are missing.
hw.acpi.video.lcd0.economy=10
hw.acpi.video.lcd0.fullpower=40
hw.acpi.video.lcd0.brightness=15


... now the whole of "hw.acpi.video" stub is missing. Nothing has
changed in terms of how/when "i915kms" & "acpi_video" are loaded (via
"kld_list" variable via "/etc/rc.conf" in that order).

What am I missing?

Does backlight(8) works for you?
