CONFIGURATION:

  • HP Elitebook 8440p: NVIDIA Corporation GT218M [NVS 3100M] (rev a2)
  • Ubuntu 16.04

SYMPTOMS of failed wake-up from suspend:

  1. "TV Static"
  2. black screen: suspend invoked by lid-close
  3. white screen: suspend invoked by power button

What test can be done to determine the root cause \ corrective action?

You should start from https://wiki.ubuntu.com/Kernel/Debugging, and more specifically:

Then probably you should submit a bug report. If you get confused or need help on what you did find you may ask here.

  • One thing may worth to try:

    1. Switch to console tty1 using AltCtrlF1

    2. Login & run

      sudo pm-suspend

    If it does suspend, try resume

    1. Press power on
    2. When you are back to tty1, AltCtrlF7 to go back to Desktop (tty7)

  • Second way to try, it works for me in XFCE/Mate 16.04 with nvidia proprietary driver.

    1. After resume, switch to console tty1 using AltCtrlF1
    2. Login

    3. Search for any screen-saver or screen-locker

      ps aux | grep -i -e saver -e locker

      Example: light-locker, xscreensaver ...

    4. Kill them

      sudo kill <PID>

    5. Check again with step 3

      It fine, either they disappear or have different PID's (means they restarted)

    6. Switch back to tty7, AltCtrlF7 to go back to Desktop

  • It freezes for me after trying to switch back to tty7 (ASUS X555UF) – vp_arth Dec 05 '16 at 09:47
  • @vp_arth, That a quick trick that work for some cases. As it doesn't work, you should go with bug report, I already included the link to debugging instructions. – user.dz Dec 05 '16 at 10:03

For me, what works, is press Ctrl+Alt+F8, to wake the computer up, then do Ctrl+Alt+F7, to go back to your desktop.

Same issue on my HP Stream 11 (with Intel Celeron N3060)

use the NVIDIA proprietary drivers listed in the screenshot you provided. Choose the top choice: NVIDIA binary driver - version 340.96 from nvidia-340

After several trials, I was able to hibernate my Inspiron 531.

Edit the file:

/var/lib/polkit-1 /localauthority/ ...

or

/etc/polkit-1/localauthority/...

Create a Desktop Entry file as follows: 

[Desktop Entry]
Encoding = UTF-8
Version = 1.0
Type = Application
Terminal = true
Icon [en_US] = gnome-panel-launcher
Exec = sudo pm-hibernate
Name = Hibernate

Here is not a solution but a workaround you can live till real solution is available.

I tried many solutions including updating NVIDIA driver to recent ones. But nothing worked. I upgraded to 17.1 but no solution. Now, in 17.1, I see when I lock screen and it goes to suspend then it can wakeup correctly. So, try in older version as well as workaround. Otherwise, it was very painful to reboot system. Now, just lock before you leave your system.
