[Sam Morris]

Perhaps. The specific bug in gnome-session (separate from the bugs in
gdmflexiserver and gdm) is that it does not cope with its child
processes (such as gdmflexiserver) not exiting immediately. It's fairly
likely that the same problem caused bug #26419 as well.

Actually I'll unreject this bug from gnome-session since I really think
it should be altered to not totally melt down if a child process hangs
(à la http://bugzilla.gnome.org/show_bug.cgi?id=432618). I''ll stop
spamming you all with comments on this bug report now too. Thanks seb :)

The bug is similar to bug #26419 then, having some indication of why
it's hanging would be nice

[Bug 108761] Re: Couldn't open any new programs or log out

[Sam Morris]

Right! It turns out that my lo interface _was_ the culprit after all. It
seems GDM wanted to use ipv6, which my firewall script blindly dropped.
Now that I have changed it to accept ipv6 packets to/from the lo
interface, all is well again!

[Bug 108761] Re: Couldn't open any new programs or log out

Here's a backtrace from gnome-session while it's hung:

#0  0xe410 in __kernel_vsyscall ()

#11 0x082457b0 in ?? ()

logout.c:886 is the line where gnome-session spawns gdmflexiserver
--startnew. So this is gdm after all. Although gnome-session's handling
of a command that never exits needs to improve--I'll file that upstream.

(Can launchpad bugs be cloned/split?)

Likely to be due to gnome-session then, not easy to debug without
getting the bug though

And if I open a terminal, then try Switch User, then unset
SESSION_MANAGER in the environment, I can open a new xterm. So it is
probably my old nemesis, gnome-session, that is the culprit here.

[Bug 108761] Re: Couldn't open any new programs or log out

[Sam Morris]

I also tried strace on a few other programs. vim hangs while reading
from a socket under /tmp/.ICE-unix; the socket is owned by gnome-
session. So maybe it's gnome-session that is screwing up.

lo interface works fine; the bug can be triggered by trying to switch
user; I've not tried suspend as it's never worked on this (desktop)
machine. Restarting bonobo-activation-server does not help.

[Sebastien Bacher]

Thank you for your bug. Does your lo interface works correctly? Do you
have a way to trigger the bug? Does it happen after using suspend or
something? Does restarting bonobo-activation-server unblock it?

[Bug 108761] Re: Couldn't open any new programs or log out

[Sam Morris]

I've noticed some more oddness today. When the screen is locked, and the
Switch User button is pressed, nothing happens. When I go to Quit ->
Switch User, the mouse cursor goes into the 'busy/launching a program'
animation. From then on, I can't open new programs, and if I select Quit
again, nothing happens.

I once got an error dialog saying that GDM couldn't be launched, but I
didn't write down the exact message, and I haven't managed to trigger it
again.
