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

[Sam Brookfield]

Affects HP Spectre z360 also (suspend works from interface but does not
happen when lid closed despite setting in power settings) - had to both
upgrade to kernel 4.4.8 from 4.4.0 and add the workarounds to
/etc/systemd/login.d to get it to work - just upgrade / workaround did
not work separately. No multiple displays or dock (xrandr confirmed) -
but haven't checked if power connecter removed works without workaround
(not any use to me).

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

Status in systemd package in Ubuntu:
  Incomplete

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.
