Cannot inc/dec brightness with smaller steps

Hello friends,

I am wondering if i can change the increase or decrease step of brightness steps in Plasma.
Meaning when i press Fn key and brightness key the brightness must increase from 5% to 6% instead of 5% to 10%.

I am new to linux and i want to know if we can change it or not, if we can how to change it.

Thanks to everyone in advance for helping me.

Re: Cannot inc/dec brightness with smaller steps

If you have an intel CPU you can directly echo values to /sys
for example

echo 250 /sys/class/backlight/intel_backlight/brightness

try with different values and when you find an agreeable gradation then write a small script to increase/decrease brightness.

# echo > 250 /sys/class/backlight/intel_backlight/brightness

FTFY.

Note that there are various backlight utilities (full disclosure: I wrote one of those) which can simplify this process. If you find one you like, you can bind the brightness keys to your preferred commands.

All the best,

Is there any way to remap the keybinding for fn+f5 and fn+f6 on plasma for executing command for brightnessctl.

or any way to use brightnessctl as default.

Thanks and sorry for replying late i was busy with some work here.
