Title:
Dell XPS 13 (9360) defaults to s2idle sleep/suspend instead of deep
(suspend to ram)
Status in linux package in Ubuntu:
Confirmed
Bug description:
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.
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).
