[Bug 1862797] Re: Systemd does not allow hibernation when Chrome/chromium is running

[Dan Streetman]

can you please update the bug description to accurately describe how to
reproduce the bug; then you should check your logs to see why the first
hibernate attempt fails.

Title:
  Systemd does not allow hibernation when Chrome/chromium is running

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  1/ Linux Mint 19.3/Ubuntu Bionic 18.04 LTS
  2/ systemd: Installed: 237-3ubuntu10.38
  3/ & 4/ Problem: hibernation stops working as soon as you start Chromium

  Steps to reproduce

  $ busctl call org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager CanSuspend
  s "yes"
  $ busctl call org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager CanHibernate
  s "yes"

  start chromium
  $ busctl call org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager CanHibernate
  s "na"

  $ sudo systemctl hibernate    
  Failed to hibernate system via logind: Sleep verb not supported

  When this happens Cinnamon/Gnome no longer show hibernate buttons of
  course.

  $ systemd-inhibit --list 
       Who: ecotech (UID 1000/ecotech, PID 1607/csd-media-keys)
      What: handle-power-key:handle-suspend-key:handle-hibernate-key
       Why: Cinnamon handling keypresses
      Mode: block

  Systemd-inhibit does not mention anything Chrome/Chromium related
  Stop Chromium and hibernation works again.

  Can also not file a bug @ https://github.com/systemd/system since my version is more than 2 versions older than the last version (2.44.1).

  Thanks in advance
