Public bug reported:
Intermittently I cannot reboot/restart from lightdm or from the
"Shutdown..." menu on the Unity panel.
Unlike bug #984163m, I have not installed gnome-shell and I am running
unity-2d.
I tailed the syslog and logs in /var/log/lightdm and the only thing I
saw when I attempted a reboot, were the following messages in syslog:
Jun 16 11:11:20 e510n acpid: client 10643[0:0] has disconnected
Jun 16 11:11:20 e510n acpid: client 10643[0:0] has disconnected
Jun 16 11:11:20 e510n acpid: client connected from 10643[0:0]
Jun 16 11:11:20 e510n acpid: 1 client rule loaded
Jun 16 11:11:21 e510n acpid: client connected from 10643[0:0]
Jun 16 11:11:21 e510n acpid: 1 client rule loaded
The lightdm logs were silent.
It is very intermittent. Is there any information I could gather the next time
it happens to help in the debug?
