Sometimes doesn't log me in automatically

When I boot up openSUSE 11.2, sometimes it logs me in automatically (which is the setting I have) and sometimes it doesn’t. How do I figure out why this is occurring?

Maybe you are not shutting down properly??

Not that I can tell. I always choose shutdown from the App Launcher and it’s always shut off without any errors showing.

Which desktop?

Personally I never use auto-login
Makes problem solving much simpler if your machine will boot without trying to startx
Try disabling auto login and see if it always boots to the desktop when you login.

You didn’t tell us what happens when it fails, does it just fall back to the console login?

Yes, when it doesn’t go through it’s at the GUI that asks me for my password.
