No, those are actually intentional failures I'm injecting to trigger the
failsafe mode.  Those are just caused by my invalidating the xorg.conf.

It looks like the real issue occurs later on:

Aug 28 12:04:17 dorset gdm[5375]: DEBUG: gdm_server_spawn: '/etc/gdm/failsafeXServer :0 -auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7

It looks to me like gdm has successfully launched the failsafeXServer
but doesn't realize it.  It's waiting for some sort of signal from the
failsafe server in do_server_wait(), that I guess isn't getting sent?

Is there some sort of signal I need to have the failsafeXServer send
back to gdm?  If so, how is this done?

Also note I'm not doing any of the X authentication - is something
dependent on having the auth keys set up?

Thanks,
