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! ** Changed in: gnome-session (Ubuntu) Status:

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

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 :) ** Changed

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

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. -- Couldn't open any new programs

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

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? ** Changed in: gdm (Ubuntu) Importance: Undecided = Low Assignee: (unassigned) =

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. ** Changed in: gdm (Ubuntu) Status: Needs Info = Unconfirmed -- Couldn't open any new

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

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. -- Couldn't open any new programs or log out https://bugs.launchpad.net/bugs/108761 You received this

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. -- Couldn't open any new programs or log out https://bugs.launchpad.net/bugs/108761 You received this
