Hi John,

You can flash the Saucy 'installed system' directly to a USB drive and
run it on your computer. That way you get a direct comparison between
Raring and Saucy on the same hardware. You must remember that I have
different hardware (probably a similar graphics chip, but if I read your
description correctly, they are different).

https://help.ubuntu.com/community/InstalledSystemFakePAE

This installed system has (as it is without any update/upgrade)

lightdm 1.7.7-0ubuntu1 (and the latest version is 1.7.7-0ubuntu2)

lightdm-gtk-greeter 1.6.0-0ubuntu1 (also the latest version)

Best regards
Nio
