I have a Dell 7737 laptop, and with Ubuntu 16.04 it no longer suspends when the laptop lid is closed. With 14.04 closing the lid put the laptop to suspend as expected. However, I reloaded the system with Ubuntu 16.04 and now closing the laptop does nothing. The laptop continues to run as if nothing happened.
When I manually select "Suspend" from the menu it works as expected. (Though it does prompt me to double login on resume. No, not encryption login followed by OS login. This is a double OS login.)
NOTE: Altering the System Settings|Power doesn't seem to affect anything.
Any ideas on what changed from 14.04 to 16.04 in this area?
