lightdm uses the following dependencies:

# Should-Start:      console-screen kbd acpid dbus hal consolekit
# Required-Start:    $local_fs $remote_fs x11-common
# Required-Stop:     $local_fs $remote_fs

gdm uses:

# Should-Start:      console-screen dbus network-manager
# Required-Start:    $local_fs $remote_fs
# Required-Stop:     $local_fs $remote_fs

kdm uses:

# Required-Start:    $local_fs $remote_fs
# Required-Stop:     $local_fs $remote_fs
# Should-Start:      console-screen kbd acpid dbus hal krb5-kdc
# Should-Stop:       console-screen kbd


While sysvinit has changed quite a few things since the last
version which worked with lightdm, there's very little there to
indicate anything which would affect lightdm.  It's most likely
that there's something wrong with the lightdm dependencies above.
Please do see if there's something missing, or "should" rather
than "required".

Is the x11-common dependency needed? --why do gdm and kdm omit this?
Are there any lightdm dependencies missing?

I've installed lightdm on my system, and I do see the occasional
failure to start.  This would indicate some race in parallelisation
which would be indicative of a missing dependency.
