Comment 38 for bug 104957

Well in that case, I'm marking the gdm Ubuntu task as invalid. The Debian shadow maintainer has agreed that /etc/securetty should mark these X displays as trusted. This hasn't entirely been implemented yet since fusa jumps straight to :20 as its next display number and /etc/securetty only goes up to :3 currently, so this still needs to be implemented (either by supporting wildcards in pam or by listing out all the displays in /etc/securetty), but in either case no code can or should be changed in gdm for this.
