Well, if you want some debugging output, try adding the -x flag to the
#!/bin/sh line in /var/lib/dpkg/info/{g,w,x}dm.postinst scripts.
Well, that's a neat trick. Here's partial output of "apt-get install
gdm"; I'm not sure what it means.

Also, try running dpkg-reconfigure on the packages in question.
Results:
fafsa-01[westk]:/var/lib/dpkg/info> sudo dpkg-reconfigure gdm
/usr/sbin/dpkg-reconfigure: gdm is not fully installed
fafsa-01:~# update-alternatives --config x-session-manager
There is only 1 program which provides x-session-manager
(/usr/bin/gdm). Nothing to configure.
fafsa-01:~# /etc/init.d/gdm start
Not starting GNOME Display Manager (gdm); it is not the default display
manager.fafsa-01:~#
This is all because x-session-manager is no longer used to choose the
display manager. Instead, a debconf hack is used to create
/etc/X11/default-display-manager, which contains the name of the display
manager to use. /etc/init.d/gdm is telling you above that gdm is not
listed in that file. I suspect that the reason you're having this
problem has something to do with the debconf mechanism involved, but I
can't say for sure. The suggestions I gave above should yield some
interesting info.
The 'default-display-manager' referred to 'wdm', so I changed it
manually to 'gdm' and then tried to uninstall gdm. Still failed. So then
I tried to uninstall wdm, and here's the transcript:
fafsa-01[westk]:/etc/X11> sudo apt-get remove wdm
