I just installed on Ubuntu 14.04.3 on my laptop (Lenovo Thinkpad X230). Everything works fine except:
- closing the lid
- pressing power button
while the computer is on does nothing, even though I have the settings (under System Settings => Power) that both should trigger hibernation. (Hibernation works fine when I pick it from the menu; also, nothing happens if I set the power button/close lid actions to suspend/shutdown, either.)
Using a script that prints out the value of
every second and then closing and reopening the lid shows that the event is not detected at all. I have kernel 3.16.0-38-generic installed.
How can I fix this?
