Won't come back from suspend 16.04 LTS
Solution 1
I had similar issue with not waking up after suspending, leaving me with black screen and processor running. There seems to be a bug in linux kernel that Ubuntu 16.04LTS is using. So upgrading the kernel to 4.4.8 solves the problem.
You can download the kernel for your system from here and set up.
Hopefully that solves your issue.
Solution 2
Adapted from this answer on askubuntu:
Use TuxOnIce kernel with uswsup for suspending
-
Double check if your swap partition/file is setup correctly in
/etc/default/grub
; you can do so by checking the location with eithercat /proc/swaps
orswapon -s
; or you could better yet, find out the UUID or label of the swap partition/files(s) and use that:tail -n -9 /proc/swaps | cut -d ' ' -f 1 | xargs sudo blkid
Edit
/etc/default/grub
by finding the line withGRUB_CMDLINE_LINUX_DEFAULT=
, add your swap partition inside, and save. If you use the UUID, prefix it withUUID=
or/dev/by-uuid/
.-
Add the TuxOnIce stable repository:
sudo add-apt-repository ppa:tuxonice/ppa
-
Install TuxOnIce kernel & uswsup:
sudo apt update sudo apt install uswsusp linux-generic-tuxonice tuxonice-userui
Restart your computer (
reboot;
)

Mookey over 1 year
There used to be a workaround with enabling suspending and hibernation, which worked for me at 14.04 LTS, but having cleanly installed 16.04 LTS I lost that, and now my computer won't come back from suspend.
I tried the tutorial listed here: http://ubuntuhandbook.org/index.php/2014/04/enable-hibernate-ubuntu-14-04/ to enable hibernation but running
sudo pm-hibernate
Leaves me with black screen and processor running, I cannot restore the system, I can only manually shut it down and run again.
Yet my SWAP is bigger than my RAM (8.5 GB).
So I cannot hibernate nor suspend (the latter I can, but the computer doesn't wake up until restarted).
Please help?
