Running Ubuntu 12.04 with xfce desktop.

When I do a suspend my monitor fades to black, prints some information to a console, and then shows the screensaver. It does not suspend.

This happens when I choose Suspend from my Panel widget, or when I run "xfce4-session-logout --suspend"

What are the next steps to diagnose this? Any ideas what might be broken?

What happens when you run sudo pm-suspend? – January Sep 17 '12 at 7:07
@January when I run this my system pauses for about .5 seconds and then the desktop reappears. <br/> When I run "sudo xfce4-session-logout --suspend" I receive the error message in a dialog box: Failed to receive a reply from the session manager. The name org.xfce.SessionManager was not provided by any .service files. – Jen S. Sep 17 '12 at 8:24
Nevermind what xfce4 says; the pm-suspend doesn't run correctly. Run it again, then type dmesg and post the output. – January Sep 17 '12 at 8:51

OK, we are getting nearer. Please post also /var/log/pm_suspend.log. Also, is this a Lenovo laptop? – January Sep 17 '12 at 9:20
