change keyboard layout in slim login screen to dvorak and how to change backround
 

how would i change the keyboard layout on slim login screen. My system and x are in dvorak but not my login screen. also how would i change the backround of slim.

The GUI keyboard is set up after you log in, because two people sharing a computer might want things done differently, so the keyboard layout for the log in has to be done separately. Have a look at this documentation: Keyboard
Things may not be exactly the same for you — Arch uses /etc/X11/xorg.conf.d/10-evdev.conf while my PCLinuxOS has /etc/X11/xorg.conf.d/00keyboard.conf — but you should be able to find the file to edit.

For background, Background

PS It does help if you specify your distro and GUI in your profile as I do.
