closing the lid doesn't suspend after upgrading to 15.10

[Adam Funk]

Since I upgraded my laptop to 15.10, closing the lid no longer
makes it suspend or even lock the screensaver.  When I close the lid,
it leaves the stuff below in the syslog.  If I run 'sudo pm-suspend'
from xterm or a virtual console, it suspends correctly.  This happens
with both the 4.2.0-18 & 4.2.0-19 kernels.  I'd appreciate any
suggestions for fixing this.

Thanks.
