I'm running archlinux kernel 5.11 (installed from Feb 2021 ISO) without a GUI (no XOrg). It boots directly into terminal.

I'm getting a "Segmentation Fault (core dumped)" at the resolution line when I run fastfetch.

Neofetch will show that line as "Resolution: preferred".

You can reproduce the issue by booting into a newly created VM with the latest archlinux live ISO, and install archlinux with this script. It wipes /dev/sda by default but you can modify that script if needed after cloning it.

pacman -Sw glibc lib32-glibc
Then enable the testing repo in /etc/pacman.conf
pacman -Syy
pacman -S glibc lib32-glibc

pacman -Sy git
git clone https://github.com/Mordillo98/archlinuxinstall
cd archlinuxinstall
chmod +x minimalarchinstall.sh
./minimalarchinstall.sh

reboot. Install your package "yay -S fastfetch-git"

do the fastfetch command. You'll see the problem.

Thx !
