Hi Yves-Alexis & Cameron,

first of all, thanks for the feedback. Replies inline below.

Indeed, that's been the case since AppArmor 2.9 reached Debian :)

Sorry I didn't ping all maintainers yet to tell them they can revert
the changes we had them do earlier in the Jessie cycle. (I've done so
for cups a few days ago, but forgot about lightdm.)

So, I've had a look at the lightdm 1.12.2-1 source package, and
indeed, at least these parts of patches/02_fix-apparmor-profile.patch
can now be dropped:

-  #include <abstractions/dbus-accessibility>


-  signal peer=@{profile_name},
-  ptrace peer=@{profile_name},
-  # needed when logging out of the guest session
-  signal (receive) peer=unconfined,
+  # this doesn't work with the current Debian apparmor
+  #signal peer=@{profile_name},
+  #ptrace peer=@{profile_name},
+  ## needed when logging out of the guest session
+  #signal (receive) peer=unconfined,

If you're running sid, then you would be the ideal candidate to ensure
any future lightdm breakage caused by its AppArmor profile turns on
red lights in a timely manner, even if Yves-Alexis doesn't test the
packages he uploads with AppArmor enabled :)
