Fix GDM Login Hangs

Ever downloaded that really cool GDM login for Ubuntu from to then see in terror that it causes you to be unable to login?  I have and I have set out to find a fix.  The fix is actually pretty easy.

Normally the GDM login themes you get tend to work very well, but sometimes they cause problems.  I am here to give you the fix.  Follow my procedure below.

I do recommend that once you fix the problem that you turn off automatic login as this is a security risk.  I hope this helped.
