ddcbc-gtk - A GTK Interface for changing monitor brightness

Ahad12 · 2021-01-03 02:14:02

Hi All,

I've been working on a simple application to change the brightness of my monitor. I tried using ddcui, but I found it too slow since it read all of the availble features each of my monitors had. So I learned GTK and DDCUtil's C API's and created my own interface for changing the brightness for each of my monitors. Feel free to submit an issue/pull request, I will review them as soon as I can! Let me know if y'all want an aur package for this, I might create one later this week .

Your post send me into a nice rabbit hole with ddcutil. I didn't know I could also control the brightness of my external monitor.

I have ddcutil working but I cannot get your program to compile. If I call build.sh I get no output at all, if I run the gcc command with -v it get:

[phaedrus@argon ddcbc-gtk]$ gcc -g -pthread `pkg-config --cflags gtk+-3.0` -o ddcbc-gtk main.c `pkg-config --libs gtk+-3.0` -lddcutil -v
Using built-in specs.
