Hi there! Unfortunately after the last 2 updates xbacklight is not working anymore on my manjaro openbox installation. The hotkeys are not working anymore, also. Is there anyone who can point me to the right direction in solving this issue? Thank you very much and keep the great work up!

Glad to see that you understand my english !
Look here: Backlight - ArchWiki and here : [SOLVED]How to enable brightness in Xfce, Openbox and i3 - ArcoLinux -D -B Forum
Maybe to help you

The backlight are controlled by XF86MonBrightnessUp and XF86MonBrightnessDown
When you press those keys a program called xbacklight is called with arguments to raise and lower the backlight. You can check the functionality by running the command in terminal.
xbacklight +10
and
xbacklight -10
If you do not have it you can install a power manager like xfce4-power-manager which provides handlers for setting the backlight.
I haven’t been using my laptop for a while so I haven’t noticed - but I will check.

Hi. It seems that xbacklight from xorg-xbacklight package might not work with your graphics drivers
Quote from Archwiki:
Note:
You can try xbacklight implementation from acpilight package. It is backward compatible and has some extra features. Maybe that will work.

Thank you all for the kind help!
xfce4-power-manager works well on my system tray, thanks!
I installed acpilight but it look like i should sudo it in order to work. I used to have a command configured in kde-connect to dim my display from my mobile phone. Is there a way to run xbacklight from “acplight” without sudo privileges?
Thank you all for your help!

Tested with Intel GPU (630) using modesetting driver and acpilight package
Steps to enable backlight keys using acpilight and XF86MonBrightness{Up|Down} on Openbox based systems.
Install the package acpilight.
Add yourself to the group video
sudo gpasswd -a $USER video
Restart your system - otherwise acpilight may not function as expected.
The following should not be necessary - provided as an alternative
Ensure your user is member of wheel group (the install user on Manjaro is member of the group)
Add the following rule to /etc/sudoers.d to allow xbacklight to be run without password
echo "%wheel ALL=(ALL) NOPASSWD:/usr/bin/xbacklight" | sudo tee -i /etc/sudoers.d/10-xbacklight
Then create an alias in .zshrc (openbox has used zsh for years) so unless you changed it this should do
echo 'alias xbacklight="sudo xbacklight"' >> ~/.zshrc
Log off and login to make sure it work and the alias is loaded. Now you can set backlight using the designated keys as defined in ~/.config/openbox/rc.xml.

Another way to use acpilight without sudo is to add the user to video group. The package has an udev rule so that members of video group can set brightness without sudo.
~ >>> cat /usr/lib/udev/rules.d/90-backlight.rules
# Allow video group to control backlight and leds
SUBSYSTEM=="backlight", ACTION=="add", \
RUN+="/bin/chgrp video /sys/class/backlight/%k/brightness", \
RUN+="/bin/chmod g+w /sys/class/backlight/%k/brightness"
SUBSYSTEM=="leds", ACTION=="add", KERNEL=="*::kbd_backlight", \
RUN+="/bin/chgrp video /sys/class/leds/%k/brightness", \
RUN+="/bin/chmod g+w /sys/class/leds/%k/brightness"

thank you for that tip - I will check tomorrow.
Thank you! I followed your indications. I then used obkey and added “sudo” in front of the xbacklight Actions. Now it’s working, again many thanks!
