Use 'Control centre' and LOGIN
I'm new to linux too... I'm using mandrake 8.0 (I have redhat and tried suse too but, Mandrake is much easier but, not a breeze for me).
There should be a 'user control' icon, in Mandrake it's a 'mandrake control center'... There you will see LOGIN options and set NO Password requirement and even NO Login... There will definately be a program/application or configuration option for you,,,just click around and if it demands a password it has POWER!
As i said, I'm new too.=)
