Description Tom Wijsman 2013-07-17 09:04:16 UTC 
Created attachment 249369 [details]
/etc/dbus-1/*

Versions used are: gdm-3.8.3.1, dbus-1.6.12, glib-2.26.3, dbus-glib-0.100.2, systemd-204, accountsservice-0.6.34; if you need to know more, feel free to ask.

With the default gdm.conf; I directly get the following message:

dbus[2706]: [system] Rejected send message, 1 matched rules; type="method_call", sender=":1.266" (uid=0 pid=31484 comm="/usr/sbin/gdm ") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination=":1.267" (uid=0 pid=31487 comm="/usr/libexec/gdm-simple-slave --display-id /org/gn")

With a more permissive gdm.conf; I get the following message after a timeout of 25 seconds:

gdm[11439]: Failed to give slave programs access to the display. Trying to proceed.

Attached you will find my /etc/dbus-1 directory; the gdm.conf is the default gdm.conf (also available as gdm.conf.gentoo) whereas the gdm.conf.permissive is the one that causes the timeout to happen.

Do you have any idea why this might happen? I get a black screen instead of gdm.

not entirely sure why it's happening. Presumably, we're blocking access to something that's disabling a code path that when enabled breaks the slave.  It could be fall out from the ConsoleKit->logind conversion or so.

Shouldn't be too hard to fix, but I haven't given it priority because it "works" as-is.  Would be good to mop this up though.

*** This bug has been marked as a duplicate of bug 702588 ***
Comment 2 Tom Wijsman 2013-07-17 12:13:21 UTC 
So, does this mean that the black screen that I see is not a result of this?

If so, I'll look further as well as await resolution on the other bug. Thank you.

I think blocking GetAll hides a bug, by unblocking GetAll the bug exposes itself.
