Change percentage of increase and decrease of screen brightness

Question

Currently I work in manjaro on a laptop with KDE, the problem that appears to me is the following: Increasing or decreasing the screen brightness goes from 7 to 7. But I need the increment to be 5 by 5.

I have tried the following:

xbacklight +5

Try modifying the scale file that is in:

/ sys / class / backlight / intel_backlight

But it does not allow me to update it even granting r / w permissions

Answer 1

Try

xbacklight -inc 5

and

xbacklight -dec 5

You can even set keyboard shortcuts to use the commands with hotkeys, if you want, in System Settings > Shortcuts, I think (I just started with KDE but I've done it for years in Xfce).

Also, the /sys directory doesn't have normal files you can change. It's an ever-changing virtual filesystem similar to /proc.
