Whenever I close the Laptop without locking/logging off, system goes unresponsive. Unresponsive in the sense it doesn't shows login prompt or not even some error message. However, there is no problem when I lock/log off system before closing the lid of my laptop. I am able to use the laptop only after removing and adding the battery to the slot(bad habit, still this is the solution I found). Even the force shutdown - long press of Power button is not working.

The issue happens irrespective of running applications.

One more thing I noticed is that LED indicator for hibernate is glowing as if the laptop is hibernating when in unresponsive state.

Ubuntu version : 14.04 Hardware : Dell Inspiron 3437

Please suggest some solution. Thanks.

  • Try the nvidia-current drivers instead (or bumblebee-project.org) – s3lph Sep 1 '14 at 11:45

May not be appropriate as a definitive answer but I don't have the privilege yet to post comments.

Have you checked that you energy management is not set so that your computer goes in hibernation or suspend-to-disk mode when closing the lid (screeen) ?

If this is the case, then you have two solution:

  • Set up your computer to go properly in hibernation or suspend-to-disk mode (maybe tricky)


  • Disable set the energy mode option on "Do nothing" when closing the lid.
