[Bug 1848771] Re: Reboot after resume from suspend (deep)

[Edward Gibbs]

Add me to the list of those having this issue, but also have a partial
fix.  I am running a Thinkpad P50 with Nvidia display adapter.  18.04
was great, never any issues with suspend or resume.  I upgraded to 20.04
a couple of weeks ago and immediately began encountering the reboot on
resume issue.  Suspend worked fine, the LED on the cover dimmed and
brightened to indicate it was asleep, external displays went into power
save, etc.  But when trying to resume it rebooted from scratch every
time.

I found this article https://itsfoss.com/ubuntu-close-lid-suspend/ and
followed the steps in it.  To my surprise, pm-utils was not installed,
so I installed it.  I also made the suggested edits to
/etc/systemd/logind.conf plus a few more, my edited file is below.

After these steps, I can now resume from suspend successfully.  My
laptop display remains dark but the external monitors come on and show
the desktop.  If I logout and back in then all is fine and all displays
work.

Here is my edited config file:

Bug description:
  After upgrading to Kubuntu Eoan (19.10) yesterday, my laptop crashes
  after resume from suspending. This is regardless the way of suspending
  (closing lid, selecting suspend from sddm, systemctl suspend).

  The journal shows:
  ferry at chromium:~$ journalctl -b -1 -e
  ..

  On resume (keypress, open lid) resume starts but immediately crashes
  and reboots.

  The laptop is an Acer 720p Chromebook with Chromium replaced and
  working fine with Kubuntu since 5 years or so.
