Thanks Brian for the detailed directions.

OK, I already had something quite similar to this. I select the Plain 
greeter, tick accessible login and restart (log out). GDM fails to come 
up, only showing the spinner and running the CPU full out, it seems.

I found a log file though! /var/log/gdm/:0.log (attached) seems to show 
a conflict with the wacom tablet, which is a specific ubuntu xorg config 
(and the one causing GOK problems to crash for a long time)

And sure enough ... commenting out all the wacom stuff in 
/etc/X11/xorg.conf brings GDM back to life with the old style greeter. I 
guess the wacom settings are needed to to support tablet PCs, so should 
probably be fixed though.

Even the themed greeter runs now and Ctrl+o does indeed bring up Orca 
(in magnifier mode). Right, time to test the individual options in more 
detail ...
