Cannot log in on 11.3

English Install/Boot/Login
#1

Greetings,

Seems something broke on the authentication for my system. Recently upgraded an 11.1 to 11.3 on VMware (guest on ESX).

At the console (gui) after I enter a username and password I’ll get the message ‘Unable to open session’. After a few more attempts the machine will simply respond ‘Module is unknown’. This happens for any user, even root.

If I attempt a SSH connection via Putty I am prompted for credentials. As soon as I enter the password the connection closes. If I enter an incorrect password I am prompted 3 times until it aborts, so it is recognizing the credentials.

What is the prescribed method for tackling this problem? Strange part is that all my services are running - email, www, etc. I just cannot log into the system in any manner.

Thank you

Up grading from 11.1 to 11.3 is not recommended. Do a new install, preserving any data you need.

You did not say if the GUI was KDE or Gnome.

So what desktop GUI are you logging into, or trying to log in to? Do you show the sessions selection down on the bottom left of your screen. If you use KDE, you could try GNOME, LXDE or xfce desktops. If I mess up KDE I just switch to GNOME, run YaST and fix or reload KDE and try again. LXDE and xfce are real small and may work when other desktops will not. In any event, it does not sound like a password problem, but a desktop startup problem.

Thank You,

Thanks for the response.

I am primarily running Gnome, but this problem is affecting all the session options. LDXE and xfce also have the same issue. Even attempting to SSH into the box fails.

Since the older repair boot option no longer exists, is there a way to diagnose/fix this problem using some Live disk? I don’t know what I’d be looking for.
