Trouble logging in

[earlene hollins]

Hello,   I've been running RedHat Linux 6.x for a several months with no problems.  I tried rebooting today and got the following message after entering my login name:     Login: PAM failure, aborting Success     INIT: Id "1" respawning too fast:disabled for five minutes      INIT: cannot execute /etc/X11/prefdm    INIT: Id "x" respawning.....   I am logging in as root.   Reboots seem to come up properly.  Usually the non-X11 login is skipped and Gnome comes up and requests a login and password.    Any ideas???   i am currently using someone else's computer.  Please respond to [EMAIL PROTECTED]   thank you.   Murray Zangen
