Hi Istimsak,

In short, PAM is the module which controls passwords and timeouts.  If I
bring up the lock dialog box by hitting spacebar, and don't enter anything
in the boxes or enter wrong values, then PAM concludes that the login
session has failed.  The website I give below probably answers my question,
but it's a bit complex. [1]

My problem is, if the dialog box keeps appearing and timing out, then PAM
will prompt more boxes.  Normally, PAM will close a box if nothing is
entered or wrong values are entered, but do this only once.

looks like the xscreen session has a pam configuration file associated with
it. You can look for it in /etc/pam.d/ and read how authentication for
xscreen is supposed to behave. I will do this myself.

I know you inserted a command to lock the screen. If you removed the
command does the issue remain?

In the past screensaver-command -lock would create a blank screen that
would remain blank until spacebar etc. is struck and the lock dialog box

Now, the lock dialog box is stuck in a viscous circle with PAM.  The lock
dialog box always stays "awake" and on-screen until it times out.  Then PAM
takes over, box appears, ad infinitum.  The screen never returns to a state
when the screen remains black until a key is struck.  Having the lock
dialog box and PAM chase each other is distracting.

If I understand this correctly, when you attempted to "lock" the screen,
the lock dialog box appears, stays on the screen until it times out, then
PAM appears or something related to this I suppose, it times out and then
the lock dialog box appears again with a repeated result?

What is PAM?

How do I get back to a previous stage where the lock dialog box only
appears when a key is struck?  Am I going the wrong way with my use of

I'm running Aardvark pre-alpha.  If this is an early bug, I deserve running
an ultra-unstable version of ubuntu.
