Thanks for replying back .
One more thing , I installed the gdm from source (./configure , make ,
make install).
But now when I restart it just shows a blank screen after ubuntu logo
(Ubuntu 9.10) .
Is it because I didn't uninstall the previous version of gdm before
installing from source ?

It is hard to say.  In general, it is probably best to uninstall the
previous version of GDM before installing a new version.

Each distro has its own unique configuration for modules like GDM, so
problems could be related to how GDM was configured, or how your distro
integrates with GDM.  For example, if the system assumes that GDM is
installed to a particular file location, you may have problems if you
have installed it to a different place.  Also, each distro may apply
distro-specific patches to GDM, and it may not work without applying
such patches.  If you find it is not working, then it might be a good
idea to check with your distro and make sure that you apply any patches
needed for GDM to operate well on your platform.

You could try editing your /etc/gdm/custom.conf file so it contains
these lines:

[debug]
Enable=true

This will cause GDM to append debug messages to your syslog (the
/var/log/messages file )Then cause GDM to fail again.  After it fails,
you can check the gdm-related messages at the bottom of the syslog
file and see if it helps you understand why it might be failing.
You can share such debug output with us on this mailing list, and
we can help analyze the debug output if it isn't clear what the
problem is.

       I was just browsing through the code of GDM . What I want to do is ,
       take the username and password from the user in a gtk window
       (like the
       explorer one ) instead of the usual login procedure. So I was
       searching
       through the code as to where can I do this , but am lost with
       the code ,
       can anybody help me with that ?


   GDM makes use of PAM for authentication.  GDM just blindly displays
   whatever prompts (username/password/etc.) that PAM is configured to
   display.  You should be able to refer to the pam.d or pam.conf manpage
   for more information.

   If you wish to modify how GDM prompts the user, this would require
   either configuring PAM differently, or modifying GDM to not use PAM.

   Note that you could probably find more PAM-focused forums where you
   would likely find better help with PAM specific questions than on this
   mailing list.
