Public bug reported:
After a fresh Ubuntu 20.04 installation, the suspend is not "deep" but it is "idle".
Deep is very important, otherwise the laptop/notebook might over heat (!) if you put it into a sleeve or bag while suspended. Which happened to my notebook.
How to reproduce:
1) install Ubuntu 20.04 on a notebook/laptop
2) suspend via lid close or suspend button or gnome shell system menu
3) wake up from suspend and type
sudo journalctl | grep "PM: suspend" | tail -2
4) find the message "PM: suspend entry (s2idle)"
How to fix the issue:
1) sudo nano /etc/default/grub
2) Replace the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
with
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=deep"
3) recreate grub with
sudo grub-mkconfig -o /boot/grub/grub.cfg
4) reboot
5) suspend via lid close or suspend button or gnome shell system menu
6) wake up from suspend and run
sudo journalctl | grep "PM: suspend" | tail -2
7) find the message "PM: suspend entry (deep)"
This fixes your suspend and makes your laptop go into deep sleep, which
greatly increases suspended battery uptime and greatly decreases the
heat the notebook creates.
