I'm running Ubuntu 13.10 on my Lenovo Y500 laptop, and I'm getting strange behavior surrounding the power button. The series of events goes something like this:

  1. I turn on my computer and enter Ubuntu (I am dual-booting with Windows 8.1 using rEFInd, by the way)

  2. I press the power button on my laptop, which brings up a small gui menu on Ubuntu, allowing me to choose from several shut-down-related options. I hibernate the computer, using the gui.

  3. I turn my computer back on and re-enter Ubuntu.

  4. I press the power button. The gui menu from before briefly flashes before the computer abruptly enters a shutdown sequence without any further action on my part. It's as if it immediately assumed I had clicked on the option for 'shutdown'.

This exact series is basically how it goes every time; that is, Ubuntu will display me the menu if I'm running from a cold boot, but not if I restarted from a hibernation. How can I get this gui to come up (and stay up without it choosing for me) every time?

Additional information: I get an apport error message dialog that shows up every time I reboot after the computer immediately turning itself off.

I've got the exactly same problem with Ubuntu 14.04 LTS and Dell M4600 laptop. The problem happens with kernel 3.13, 3.14 and even 3.16. I don't use hibernate to disk very often, but I use suspend quite a lot, and typically one in 10 suspends fails - i.e. goes straight to shutdown instead of displaying the menu. Also, sometimes there are still (fortunately) rare problems with NVidia graphics not waking up properly after suspend. –  Piotr Kolaczkowski Oct 11 '14 at 15:09
Have you tried this solution to modify logind.conf: askubuntu.com/questions/451009/… –  Piotr Kolaczkowski Oct 11 '14 at 15:22
