Unfortunately, hibernate doesn't work in many cases, which can cause you to lose data if you expect your documents and applications to re-open when you switch your computer back on. Therefore, hibernate is disabled by default. You can find more information about how to fix your problem at Ubuntu Wiki - Debugging Kernel Hibernate.

I had the same issue on Ubuntu Gnome 16.04. The only solution I found at the time was updating the kernel. After update to 4.5.3-generic the problem was gone. The how-to upgrade linux kernel is described here. You can check your kernel version through terminal: uname -r

Apparently hibernation is disabled by design with secure boot, since modifying the stored memory content is a potential attack vector. There seem to exist some kernel patches, which implement signed hibernate images https://lwn.net/Articles/651274/ but I don't know whether there exist any usable packaged kernels for Ubuntu, which include those.

I’m not 100% convinced this is a 16.04 issue as this has recently resurfaced for me on 14.04.4. For me sudo nmcli nm sleep false wakes up network manager. I know I’ve had this problem before as I had a script with the above command, but I can’t remember if I found a solution or it was just fixed somewhere along the way.

I had the same problem after upgrading from 15.10 to 16.04: Closing the lid did not do anything Manually suspending with the menu item in the system tray resulted in a half suspended state with the only way out to reset the system. I solved these issues by upgrading the kernel to 4.4.8 (after this suspend from menu worked for me) Adding the line ...

By seeing your last image and EDIT 2, I can understand that Ubuntu can't find a Swap Partition on your system. So I suggest you should create a Swap partition equal to or larger than your RAM size, and try again by running sudo pm-hibernate You can create swap partition using GParted, run this to install it sudo apt-get install gparted

I was having trouble accessing the windows HD via ubuntu because when you shut down windows 10 by default it hibernates rather than shuts down. I hadn't been able to use the custom mount option remove_hiberfile... it just didn't work. Also, I tried other NTFS tools that were available and none worked. After googling a while I did what any responsible geek ...

Hibernate has been disabled by default. Try this sudo pm-hibernate If the hibernate test works, you can continue to use the sudo pm-hibernate command when you want to hibernate. You can also enable the hibernate option in the menus. To do that, use your favorite text editor to create ...

First, I do recommend that you test if your machine supports hibernation, because the reason why hibernation is disabled by default is because it sometimes has unpleasant results on some machines. Test your machine by opening the terminal (Ctrl+Alt+T) and then typing sudo pm-hibernate Your machine should hibernate. Wake your machine up after hibernation and ...

You have to manually enable it with a little effort. It's been disabled by default. http://ubuntuhandbook.org/index.php/2014/04/enable-hibernate-ubuntu-14-04/ Then, if it doesn't work, it's might be a 4.4.0 kernel issue, and you might have to upgrade kernel.

You should be able to create a script in the /etc/pm/sleep.d/ directory (or supposedly the /lib/systemd/system-sleep/ directory if you are running 15.10+) which executes that restart command on system resume. Make sure to make that script executable. Create a network_restart file in said directory with these contents: case "${1}" in resume|thaw) ...

It looks like said problem was yet again a general bug. Thanks to this thread, I installed an upstream kernel which solved the problem.

I was able to get Ubuntu 16.04 LTS installed over the last few days. Here's my notes from the installation. Multi-monitor connections via HDMI work. The thunderbolt 3 port also works for Ethernet. (haven't tested it for anything else). Please feel feel to revise this, and read carefully, as there are almost certainly some errors. I'm not a Linux expert ...
