[Bug 1574120] Re: Notebook doesn't suspend when lid is closed after update to 16.04

[mike-g2]

I have had this problem in the past and it reemerged on an upgrade from
16.04 to 18.04 and have resolved it. For me (Lenovo Yoga) the issue is
with USB rewaking the machine.

The following fix worked for me.

1) Created file: /etc/systemd/system/toggle.XHC.to.fix.suspend.issue.service
with following informaiton

[Unit]
Description="Make suspend ignore USB wake up."

[Service]
ExecStart=/bin/bash -c "echo XHC >> /proc/acpi/wakeup"

[Install]
WantedBy=multi-user.target

2) Created a symbolic link to above script in /etc/systemd/system/multi-
user.target.wants

3) Executed following commands
                sudo systemctl daemon-reload
                sudo systemctl start toggle.XHC.to.fix.suspend.issue.service

4) checked service was started with 
      sudo systemctl status toggle.XHC.to.fix.suspend.issue.service 

5) Enable it on boot with
             sudo systemctl enable toggle.XHC.to.fix.suspend.issue.service

  Notebook doesn't suspend when lid is closed after update to 16.04

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  My notebook does not suspend after upgrading from 15.10 to 16.04.

  According to system settings the notebook should suspend when lid is
  closed but actually this does not happen. Instead it continues to run
  as if nothing had happened.

  With the previous versions of ubuntu (14.04-15.10) everything worked
  fine.

  My System: HP Pavilion dv7.
