[Bug 1089105] Re: [Lenovo V480c Notebook]: System fails to resume properly from suspend

 

Through debugging, I found when the lid was closed, the system/kernel
will generate a TOUCHPAD_KEY (XF86TouchpadToggle) by a mistake, the
gnome-settings-daemon->media-keys-plugin will capture this key and
toggle the touchpad enable/disable through gnome-settings-daemon->mouse-
plugin.

On other machines, closing lid won't generate TOUCHPAD_KEY event, so the
touchpad doesn't has this problem.

Bug description:
  Problem:
  System does not resume from suspend properly. The issue is intermitent. However most of the time the system will exhibit three problematic symptoms:

      1.) System will fail to resume and start x altogether
      2.) System will resume with applications in frozen state and unity unresponsive to mouse-clicks.
      3.) System will resume however trackpad will be disabled.

  
  kernel tested: 3.2.0-29-generic #46-Ubuntu
  Release: Ubuntu 12.04.1

  Can reproduce? Yes

  Steps:
  1.) Close laptop lid
  2.) wait approx 5 minutes
  3.) open laptop lid for system to resume.

  Expected result:
  System is able to suspend state and applications and resume when lid is opened in a proper and timely fashion.

  Command to recreate:
  fwts_test  -s s3 --s3-sleep-delay=30 --s3-device-check | tee suspend_single_times.log
