Ubuntu – Hibernate and Suspend do not exist anymore, help

hibernatesuspend

When I close the lid of my laptop and open it after some time I am greeted with a message "Failed to suspend".
When I tried to manually suspend/hibernate, I saw these options are not available there at all. Of course, they did exist when I did the fresh installation but I can't see them anymore.

I am totally pissed off with this. Please help.

Finally I was able to resolve the problem by installing acpi-support from the ubuntu software centre. Here is the thread that helped me http://ubuntuforums.org/showthread.php?t=1608752

Ubuntu – Ubuntu won’t suspend anymore, but it did upon install

Open the Software center and type 'acpi-support' in the search bar. Make sure, that the package is installed. Reboot, and voilà: suspend and hibernate are back and working again for me. Maybe this will fix it for you, too.

Ubuntu – 20.04 LTS Since upgrade from 19.10 laptop doesn’t suspend anymore after lid close

I had similar with a fresh UbuntuDDE install. I found answers in various sources (this one is probably the most relevant Ubuntu 18.04 - Dell XPS13 9370 no longer suspends on lid close). The issue is the laptop not going into "deep" sleep. Run this command

cat /sys/power/mem_sleep

And if you get the result below, then this is the issue.

[s2idle] deep

To change it, edit your grub file to add this text to the GRUB_CMDLINE_LINUX_DEFAULT line

mem_sleep_default=deep

Then update grub

sudo update-grub

and reboot. After reboot, run this again

cat /sys/power/mem_sleep

and confirm now that your result is

s2idle [deep]

Then you should be good to go.
