How do I log is as another user?

[Stephen]

Automatic Log In is not selected for any user in the control panel yet it still automatically loads into the knoppix account. I have just upgraded my system (see my other post about boot error) but still it boots automatically into the knoppix account. Any help would be appreciated.

If you used the "knoppix" install method instead of the Debian then you basically just copied the CD to the HD and I do not believe you can change users you need to have done a Debian install to do what you want.
