Where to put commands to run when X starts with SLiM

I'm having trouble determining where to add these two commands: setxkbmap latam to set the correct keyboard layout, and xcompmgr -c -C & to enable transparency. Before installing SLiM, I used this recommendation, and it worked, but it stopped working afterwards. I tried adding it to ~/.xinitrc, like shown below: #!/bin/sh # # ~/.xinitrc # # Executed by startx (run your window manager from here) if [ -d /etc/X11/xinit/xinitrc.d ]; then for f in /etc/X11/xinit/xinitrc.d/*; do [ -x "$f" ] && . "$f" done unset f fi exec setxkbmap latam exec xcompmgr -c -C & exec startxfce4 But this seemed to crash it, and it just froze before starting XFCE4 (after logging in). I also tried using this recommendation from the Arch Wiki , but it didn't seem to do anything. Any recommendations? Note that I'd like these commands to be the default setting for all users that log into xfce4.
