Wow, that's new one.

I noticed few things. .xsession-errors still shows same output about 
gtk-engines and ssh-agent (not very important).

This might be a culprit for gdm failure:

_IceTransSocketUNIXConnect: Cannot connect to non-local host phoenixfusion

your "hostname" should resolve to local address (192.168.x.x, 10.10.x.x 

What does "cat /etc/hosts" say?

I recommend you add your user to group "audio" as described on 
alsa-utils page (not related, but can help you to avoid further problems).

Also, you should add user "gdm" to "audio" and "video" groups as 
described on gdm page (if not done already).

Regarding glxinfo and permission denied, that is the problem why shell 
isn't starting. Please run this as normal user and post the whole output

LIBGL_DEBUG=verbose glxinfo

And at last, does /lib/udev/udev-acl exist? (ls -ld /lib/udev/udev-acl)
