Changed GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub to acpi_backlight=video to enable backlight adjustment with fn key. I have tried native and vendor, only video works.
Now fn+up/down keys change the backlight by 1 in 0-100 interval. Is there a way to configure it to change the backlight by 5 or 10?
$ cat /sys/class/backlight/*/max_brightness
100
I’m already frustrated with command line tools to adjust the backlight. you don’t need to mention them.
Hi @srezas,
I think what you want is xbacklight. See:
https://wiki.archlinux.org/title/Backlight#xbacklight
Hope this helps!
Actually it is not possible without modifying and recompiling of xfce4-power-manager. Because it is fixed to the given hardware steps. No option to change that as I know. Probably ask/research here: Community – Xfce
It would be practical to use xbacklight and a keyboard shortcut for it. See for example here: https://superuser.com/questions/1279727/xfce-change-brightness-steps-and-or-change-brightness-key-behavior
