[Bug 1574125] Re: suspend not working after uprade


Asus U44S laptop with Optimus Nvidia Geoforce GT 610M.

Slightly different but related issue. Can suspend with by closing the
lid which didn't work in 15.10, although only without an external
monitor plugged in. But upon resume getting a hardware lockup and freeze
nearly 100% of the time. Initially it worked, but then has since stopped
working. Using Nvidia binary driver 361.42 with the Intel card turned
off under software control.

Just noticed something odd though as writing this up. Additional Drivers
lists the Nvidia drivers OK, but for the Intel card it is now reporting
"Unknown: Unknown - This device is not working." After upgrading to
16.04 from 15.10 I double checked and it reported the Intel card turned
off from Additional Drivers. Clear, something has changed.

  suspend not working after uprade

Status in linux package in Ubuntu:

Bug description:

  Upgraded from Ubuntu 15.10 where suspend workes flawlessly. After
  upgrade, putting machine in suspend turns the monitor black and
  everything seem to be off, though the fan still spins, the power light
  is on and the battery is trained. Nothing seem to wake it up (Meaning
  different key combinations - trying to get a shell by Ctrl+Alt+F1, for
  example; pressing power, any other key).

  Unsure how to try to get it working since I have to kill the power by
  pressing down the power button, then restarting it (it then does a
  drive scan for errors).
