Xrandr increase brightness in incraments

Hi, I recently installed manjaro with awesome wm, and it has worked great, apart from the brightness and volume keys. I did a lazy fix for the volume keys by adding a custom key shortcut to my rc.lua:

awful.key({ modkey },             "="        function ()
awful.util.spawn("amixer -q sset Master 5%+") end,
                {description = "volume up (%5)", group = "volume"}

This works for volume, but i wanted to do the same for Brghtness, i found that i can adjust brightness with xrandr --brightness so i can adjust via the terminal with xrandr --output eDP1 --brightness #brightness 0.1-1 and change brightness, i want to do this in a increase of 10% and not to a fixed value so +10% or -10%, how can i do this?

And you question/issue is what?

Sorry i accidentally posted it early without the question…

Updated the post, now with question

man xrandr:

–brightness brightness
Multiply the gamma values on the crtc currently attached to the output to specified floating value. Useful for
overly bright or overly dim outputs. However, this is a software only modification, if your hardware has support
to actually change the brightness, you will probably prefer to use xbacklight

Note the part i underlined…

How can i use xbacklight?

It’s in the official repos…

(sorry for being a noob)

$ pacman -Ss xbacklight
extra/xorg-xbacklight 1.2.3-2 (xorg-apps xorg)
    RandR-based backlight control application
community/acpilight 1.2-2
    a backward-compatible xbacklight replacement based on ACPI

sudo pacman -S xorg-xbacklight :slight_smile:

sorry for being such a noob
