Suspend broken on Ubuntu 16.04 LTS, Dell XPS 9350

Question

Since I upgraded from Ubuntu 15.10 to Ubuntu 16.04 LTS on my Dell XPS 9350, suspend is broken. When closing my lid the laptop will suspend, but resuming fails and it reboots. I tried pm-suspend and tried resuming, resuming failed and the laptop rebooted. I got the following errors when I got back into Ubuntu. The odd thing in my opinion is that it claims the kernel is not an official ubuntu package. Either way my Linux knowledge is not sufficient to know what's going wrong here.

EDIT: I just tried installing kernel 4.4.8 which should fix some things, but it did not fix this problem. By now I also tried 4.4.9 and 4.6 RC7. None of them fixed it for me.

Solution 1

I had this same problem on an XPS 15 9550. The only thing that worked for me was going into the bios and turning on "Block Sleep" under power options. This apparently turns off Intel Rapid Start and sleep (state 3). So technically the machine doesn't hibernate / suspend (state 3), but it does go to a higher sleep state when closing the lid / opening / power button and comes back fine. Seems like until the issue is addressed in the kernel, or driver this may be the only option and is the only thing that worked in my case.

EDIT: This script worked for me and I was able to turn off Block Sleep in bios! Sleep / suspend now works on my ubuntu 16.04: https://ubuntuforums.org/showthread.php?t=2317843&page=11

Solution 2

Resuming broke on my Dell XPS 13 9350 after I upgraded from 16.04 LTS to 17.10. When I would close the lid, as far as I could tell, the system suspended (though I'm guessing it probably crashed at that point). I see entries like this in /var/log/syslog:

Nov 22 21:42:01 foxy systemd[1]: Starting TLP suspend/resume...
Nov 22 21:42:02 foxy systemd[1]: Started TLP suspend/resume.
Nov 22 21:42:02 foxy systemd[1]: Reached target Sleep.

Nov 22 21:42:02 foxy systemd-sleep[3511]: Suspending system...

Those messages themselves don't really indicate anything unusual (at least for my system -- I'm curious what the errors mean). When I'd open the lid, I'd see a BIOS POST and the system would boot. This is reflected in the log, which had messages like these immediately following the chunk above:

Resume started working correctly after I installed the "uswsusp" package:

sudo apt-get install uswsusp

This is a solution described here: XPS 13 9350 (2016) suspend - sound issues

Now, when I suspend, I see many more syslog entries indicating the system is properly going into suspend state:

Anyway, I don't know why the "uswsusp" package was missing or entirely why it fixed the problem. Seems like it should be a required package.

Another thing that might be worth noting is that I didn't see this behavior before yesterday or maybe a couple of days ago, after not having used the computer for a few days. Suspending used to work just fine in the beginning.

Hi Rien, smells like a UEFI/ACPI setting problem. I would recommend you start reading from here: askubuntu.com/questions/770629/…

This area is over my head too. But as far as I understand it, uswsusp replaces the kernel/suspend-hibernation. Still a riddle to me why suddenly I had suspend issues after 1-2 years of no issues.

[Mike Hicks]

Argh. I believe this had been working, but now I'm unable to suspend my laptop when it's running on battery. It apparently turns off when I close the lid, and it starts booting up from BIOS when I open the lid again. Suspend functions correctly when it's on A/C power.
