Solved backlight

[fernandel]

On my Thinkpad T495 FN keys for brightness never work and I use accessibility/. But now I start to use backlight. In .xinitrc I have backlight and value and it works and I like it. External monitor I adjust with monitor settings.
Is it possible to put backlight to rc.conf or somewhere other that works when laptop start.
Thank you.

Hi fernandel,
there is more than one option. You can run backlight right after reboot using the @reboot statement of crontab(5). It is also possible to use a script start by the rc framework.

Actutally I have a script /usr/local/etc/rc.d/backlight as below.

#!/bin/sh
# $FreeBSD$
# PROVIDE: backlight
# REQUIRE: LOGIN
# /usr/local/etc/rc.d
. /etc/rc.subr
name="backlight"
desc="Initialize the backlight"
rcvar="backlight_enable"
start_cmd="backlight 50"
load_rc_config $name
run_rc_command "$1"

The script is invoked by a line in /etc/rc.conf

backlight_enable="yes"

Check BIOS/UEFI if the T495 has a hotkey mode.

On my ThinkPad E15 I had to enable hotkeys to be able to regulate backlight(8) brightness from console and Xorg with the Fn keys.

In BIOS/UEFI I have related to keyboard and all 3 options are disabled:
Fn crtl key swap
Fn sticky key
F1 - F12as Primary Function

Thank you.
