Backctl
A quick and simple backlight control using sysfs and udev
What this is
This is a super simple backlight control that adjusts the brightness value of
a backlight for me in linux using sysfs. It enumerates all the "backlight"
devices from udev and adjusts their backlight node accordingly.
Why?
I discovered that xbacklight didn't work on my new laptop. Rather than fixing the problem or using one of the many existing alternatives, I wrote this quick utility that adjusts the backlight from userspace (after the addition of a udev rule to set the backlight permissions accordingly). The utility is written in rust just for fun.
