Changing brightness is not working with FN keys on Dell Latitude
the combination of Fn with other buttons works in normal mode, only the brightness change does not work
in the previous versions of Mercury it worked well, but in Mercury Neo this function stopped
I installed:
acpilight (I don’t know why)
xorg-xbacklight
but, xbacklight +10, not working
btw, i use i3wm
Remove acpilight. Don’t need it.
Post your i3 config file.
Sorry for the late reply
I have an almost clean config file after installation
# exec --no-startup-id ~/set_once.sh
# This file is a modified version based on default i3-config-wizard config

I turned on these two lines, but the brightness Fn didn’t work
xbacklight -inc 10
xbacklight -dec 10
Check the man page of xbacklight.
brightnessctl and light are good to change screen/kbd brightness, too.
Check out subsection 1.1.1 for more help, possibly. I have an old Dell Latitude and my previous install of Manjaro using Grub was helped by adding one of the ACPI kernel parameters. Good luck!
More info:
I installed KDE, the buttons work, I installed it no desktop with other dotfiles, the buttons work, but it was I3 that caused this problem
yes the problem is indicated in the second link, but as a rookie I dont understand …boot with “acpi_backlight=video”
Are you using Grub as your bootloader?
acpi_backlight=video needs to be added to /etc/default/grub between the quotes in the GRUB_CMDLINE_LINUX_DEFAULT line
Afterwards run sudo update-grub in your terminal and reboot
systemd-boot can have kernel parameters added too if you are booting with it, and a search on the Arch wiki would provide more help
no, i use systemd bootloader
This tells you how to add them as well as keep them persistent for every boot.
