Public bug reported:
After upgrading from 14.10 to 15.04, I found that the system was going
to sleep every 30 seconds. This behavior does not manifest once I log
into the graphical desktop (Lubuntu), but if I switch over to a virtual
console, it manifests again.
A temporary fix has been to make /sys/power/state non-writable.
At first, I believed the problem was with systemd, but the problem
continues after switching to upstart.
I believe the problem is in the dbus package, because I see this every
30 seconds in /var/log/syslog, coinciding with the laptop going to
sleep:
