** Description changed:

- This is a reintroduction of 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808957 which I am 
experiencing with Ubuntu 20.04 fully upgraded on a Dell XPS 13 9360. This did 
not happen before  in Ubuntu 19.04.

+ This is a reintroduction of
+ https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808957 which I am
+ experiencing with Ubuntu 20.04 fully upgraded on a Dell XPS 13 9360.
+ This did not happen before  in Ubuntu 19.04 nor in Ubuntu 19.10 (Eoan),
+ so this issue is affecting Ubuntu kernels >= 5.4.
  
  It seems that the Dell 9360 is set to go into s2idle mode rather than
  deep sleep, forgoing significant power savings.
  
  I have confirmed this by suspending and then checking:
  sudo journalctl | grep "PM: suspend" | tail -2. If the output is
  
  PM: suspend entry (s2idle)
  PM: suspend exit
  
  cat /sys/power/mem_sleep showed
  
  [s2idle] deep
  
  As a temporary fix, I typed
  echo deep > /sys/power/mem_sleep
  as a root user (sudo -i).
  
  Then the output of cat /sys/power/mem_sleep was
  s2idle [deep]
  
  After suspending now,
  sudo journalctl | grep "PM: suspend" | tail -2 returns
  
  PM: suspend entry (deep)
  PM: suspend exit
  
  I have made this permanent by editing
  /etc/default/grub
  
  and replacing
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
  with
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=deep"
  
  then regenerating my grub configuration (sudo update-grub).

Title:
