Where to troubleshoot wake-up from 'suspend'?

Question

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?

Solution 1

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

• Debugging Kernel Suspend -- Help debugging kernel suspend/resume problems
• Debugging Kernel Hibernate -- Help debugging kernel hibernate/resume problems

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

Solution 2

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

Solution 3

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)

It freezes for me after trying to switch back to tty7 (ASUS X555UF)

@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.

Please consider adding comments to explain either why it works on your Inspiron and how you arrived at this solution.
