Bug Description
Gnome-Session 3.8+ enforces usage of 3D, breaking usage of all gnome-session based sessions in non-3D accelerated environments as non-3D enabled hardware, forwarded-X, VNC and NX/X2GO.
This breaks gnome-flashback, breaking upgrade path from previous LTS and removing most sane option for cloud environments!
Overriding 3D checks (sym-linking /usr/lib/
(Sorry for hijacking this bug, but new gnome-session behavior has much broader affect then originally reported)
Original report:
----------------
In Saucy Salamander, gdm will not start if 3d acceleration is not available. This throws an error to /var/log/

This is a regression from raring, and is the same if gnome-fallback is unavailable.
Possibly the same bug as #1251281, as this shows the same error.
This is preventing me from upgrading to raring, as I run 4 screens on an Nvidia Quadro NVS 450, meaning 3d is unavailable.

Have marked as critical as this makes saucy completely unusable as a desktop environment on non-3d machines.
