Comment 6 for bug 1228079

Same problem here, I just upgraded Ubuntu from 13.04 to 13.10
Right now I'm using pbis-open lastest version (7.5.2.1527). This versions worked fine justa few hours before upgrade.

Upgrade was normal, but when I tried to start session with any domain user I got a few flashes and returned to lightdm login screen.

After cheking the message error "/usr/sbin/lightdm-session: 5: exec: init: not found" I found another bug:
https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1184878

I made the sgestion of make a symlink running this:
sudo ln -s /sbin/init /bin/init

Now when I try to login with a domain user, I got a blank screen and mouse works, but nothing else show up. No background, no terminal with "Alt+T" combination, no bars, no icons, nothing.. Hey.. but mouse moves!

This is the new log from the file .xsessions-errors

Script for ibus started at run_im.
Script for auto started at run_im.
Script for default started at run_im.
init: unity-gtk-module main process (3055) terminated with status 127
init: logrotate pre-start process (3053) terminated with status 127

init: ssh-agent pre-start process (3054) terminated with status 127
init: ssh-agent post-stop process (3062) terminated with status 127

I got this errors using nouveau (I thought that maybe nvidia drivers were the problem, but I was wrong)
