CONFIGURATION:
- HP Elitebook 8440p: NVIDIA Corporation GT218M [NVS 3100M] (rev a2)
- Ubuntu 16.04
SYMPTOMS of failed wake-up from suspend:
- "TV Static"
- black screen: suspend invoked by lid-close
- white screen: suspend invoked by power button
What test can be done to determine the root cause \ corrective action?
Update: Driver status screenshot
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:
Login & run
If it does suspend, try resume
Second way to try, it works for me in XFCE/Mate 16.04 with nvidia proprietary driver.
Search for any screen-saver or screen-locker
Example:
light-locker
,xscreensaver
...Kill them
Check again with step 3
It fine, either they disappear or have different PID's (means they restarted)
Switch back to tty7, AltCtrlF7 to go back to Desktop
use the NVIDIA proprietary drivers listed in the screenshot you provided. Choose the top choice: NVIDIA binary driver - version 340.96 from nvidia-340
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)
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:
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.
