[Bug 29236] "Failed to start X" screen on tty2

Affects: gdm (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
The "Failed to start X" screen appears on tty2, which is OK by itself.
But when the boot process finishes init will launch a getty on top of
the "Failed to start X" screen.

There are interesting side effects for this, if the user logs in the
session works just fine until the user presses tab. At that point the
gdm dialog will take precedence and hijacks the tty.

Long story short, it might be good to launch the dialog to some other
tty, the initial idea (AFAIK) was to launch the dialog in last+1 tty,
but since gdm startup was moved up in the boot up, tty2 is not occupied
at the time of the error itself.

This has been checked with Dapper (upgraded from Breezy)
