Potential Local User Compromise

In SuSE 6.1 if I start up X from console 1 it starts the Xserver on console 7. Even through a locking program if I hit ctrl-alt-f1 I can hop back to my old console and then background that process. The security problem is if someone local to the machine was to hop on and do the same he could gain access to my account, no fuss no muss. Is there a way to defeat that bypass other than running @ Level 3 in init.d? Ben -- To Regret one's Mistakes, Is To Regret One's Experiences -O. Wilde
