I was having persistent issues when trying to launch Minecraft version 1.8.9 or lower specifically through Lunar Client while the official Minecraft launcher worked fine and after a few quick searches I found a solution that I just wanted to post here in case it could help anybody facing the same issue.
The following is the error:

Turns out that a missing dependency can cause this exception, and at least for me, installing xorg-xrandr fixed it.
sudo pacman -S xorg-xrandr
