I haven't upgraded to hardy yet, so I don't if the following information
applies, but in gutsy you can disable the failsafe mode by
editing /etc/gdm/gdm.conf and commenting out the following line:

FailsafeXServer=/etc/gdm/failsafeXServer

Of course, it X fails to load you'll now be dumped out to the console,
so its probably is good idea to test if you can switch out to a vt
(ctl-alt-f[1-6], before disabling the failsafe server.
