Where is the .xinitrc (:

[refaatcrafts]

[Aman1337g]

It is present in /etc/X11/xinit/

[Edesem]

This repo is specifically for suckless programs, your .xinitrc should be seperate and managed by yourself to have the programs that you need to load first.

At the very least it should follow the format of

exec {Program} &
exec {Program} &
...
...
exec dwm

with exec dwn having no ampersand following it.
