[Bug 51227] Re: cannot restart, logout,shutdown

[Mathieu Pillard]

I had this problem once when the lookback interface wasn't up for some reason. Just in case it's your problem here, here is a quick list of things to check:
* ping 127.0.0.1
* ping yourhostname
* ifconfig -a | grep "UP LOOPBACK RUNNING"

If any of these fail, or don't show a result, you have a problem. Check
your /etc/hosts file (is your hostname correctly setup there if it needs
to?), check your /etc/network/interfaces (got a "lo" entry? is it set to
"auto" and "inet loopback" ?)

Also, another symptom will be that stracing "gnome-session-save --kill"
will block on some network stuff with 127.0.0.1 or something similar.
