[Xorg][Tutorial] Dvorak Keyboard Map Settings In System-Wide[Archlinux]

Yet again, I've discovered an even better means of setting the keyboard layout to dvorak. Much more simple than anything that I've yet discovered. The Archwiki is such a useful place to be when you're searching for answers for a long time problem!

As root, create the file /etc/X11/xorg.conf.d/10-keyboard.conf.

Then simply add this text to the file using your favorite editor [Mine being Vim]:
 

Section "InputClass"
    Identifier             "Keyboard Defaults"
    MatchIsKeyboard       "yes"
    Option               "XkbLayout" "dvorak"
EndSection

Then restart X (or logout and back in) and you're finished!

It even works for slim [Logging in with DVORAK at long last is possible!]:
