Binary package hint: compiz
To reproduce:
1) Go to System -> Preferences -> Keyboard Shortcuts
2) Find the entry for suspend, and choose some shortcut.
3) Press the shortcut.
What I see: The screen briefly goes blank, and then returns within a second. There is no report of any attempt to suspend in .xsession-errors or in dmesg, or dbus-monitor. I don't think the suspend command is being run correctly by the shortcut, because when I choose Suspend from the panel menu (fast user switching applet, aka indicator-applet-session), it works.
A workaround:
1) Install compizconfig-settings-manager
2) Open the "Commands" preference panel.
3) Enter, e.g., for command line 0:
dbus-send --session --dest=org.gnome.ScreenSaver --type=method_call /org/gnome/ScreenSaver org.gnome.ScreenSaver.Lock ; dbus-send --print-reply --system --dest=org.freedesktop.DeviceKit.Power /org/freedesktop/DeviceKit/Power org.freedesktop.DeviceKit.Power.Suspend
(you may omit the first command if you don't want the screen to lock)
4) Switch to the Key Bindings tab, and define a key binding for the corresponding command.

Does running this command from a terminal successfully suspend your computer? Does putting `sh -c "dbus-send --print-reply --system --dest=
