how to change the login theme

im a new user to opensuse, but ive been with ubuntu for a while and decided to upgrade. anyhoo i cant figure out how to change the login theme. any ideas?

You mean the bootsplash?
If so have a look here: Custom splash screen - openSUSE

no not the boot splash, the actual login screen where you put in ur username and password.

You might use the links below as a direction to search in, but for 11 I couldn’t find it.
