Comment 4 for bug 195095

..but the following two sleeps I did didn't give me any popup about failing sleep. Difference is that these sleeps I manually triggered by issuing 'gnome-power-cmd.sh suspend'.

I get this when I do it from console every time though:

$ gnome-power-cmd.sh suspend
+ [ suspend = suspend ]
+ echo Suspending
Suspending
+ execute_dbus_method Suspend
+ dbus-send --session --dest=org.freedesktop.PowerManagement --type=method_call --print-reply --reply-timeout=2000 /org/freedesktop/PowerManagement org.freedesktop.PowerManagement.Suspend
Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
