Re: [gdm-list] gdm restart after login

It is hard to know exactly what is going wrong for you.  Either
something is wrong with the command to launch the Xserver or the
GDM GUI, or you've found a more serious bug in GDM.

I would test to make sure that you can run the Xserver command by
hand.  The gdm debug log should show you command it is using to try
and start the Xserver.  Does the same command work if try launching
X by hand with the same command?  You might check the Xserver error
log.

If you can start it, can you run programs on the display?  For
example

$ export DISPLAY=:x.y (xservercmd)&; gnome-terminal

Now you have a terminal running you should be able to run:

$ export DOING_GDM_DEVELOPMENT=1
$ /usr/lib/gdmlogin or /usr/lib/gdmgreeter

Does the gdmlogin/gdmgreeter program show up okay?

Any error messages you see doing any of these steps would indicate a
problem.  Sometimes gdmlogin/gdmgreeter won't start up properly if they
can't find a library it needs.  Running "ldd /usr/lib/gdmlogin" or
"ldd /usr/lib/gdmgreeter" is another way you can check for this error.
If the login program core dumps, it will also have the same behavior.
So changing the startup command for the login program so that it
starts it up via trace/truss might highlight if a core is happening
and might highlight why.
