I installed Fedora 29 and do not use the wayland Gnome. I use x11 with i3. However, when I went to use xblacklight to adjust my laptop backlight, the command was not found. I also tried using it as sudo and even searched for it with find and grep. I looked online and tried to find the package and could not.

    sudo dnf whatprovides xbacklight shows the fedora repo contains this. – JRFerguson Feb 25 at 12:24

It is xbacklight, if you had a typo. What does it say, when you type dnf install xbacklight?
