[DSE-Dev] Bug#683756: selinux in permissive mode breaks gdm and X

Since the last selinux update (around July 6), running selinux in
permissive mode stops gdm3 and X from working for me (haven't tried
enforced mode).

Bootup proceeds normally until X starts up, then all I get is a black
screen with the rotating DIN plug (or whatever it is). GDM never
presents me with a logon screen.

I've tried switching to slim, which does give me a logon screen, but
all session types that I've tried fail: I just get a blank screen with
the big black X.

This happens on three different machines: two desktops (both with
nVidia graphics, using the proprietary module) and a laptop (ATI
graphics, using ATI's proprietary module).

I'm surprised this happens, since I was under the impression that
permissive mode didn't enforce anything. I've had no trouble with it
in the past.

I've been running with selinux disabled on all three boxes since this
problem surfaced.
