[Bug 1318249] Re: Failure to resume from hybrid suspend


Odd, this seems to work on on my Dell Inspiron 15. Tested  "Suspend to
Disk" and "Suspend to RAM". Both gernerate the log message indicating an
image was written to disk. Both resume normally with "Suspend to RAM"
being execptedly faster. My machine was also upgraded from 13.10. I
don't know if anything older than that was installed.

  Failure to resume from hybrid suspend

Status in “xorg” package in Ubuntu:

Bug description:
  I followed http://askubuntu.com/questions/145443/how-do-i-use-pm-
  suspend-hybrid-by-default-instead-of-pm-suspend/145676#145676 to set
  up hybrid suspend, creating the file /etc/pm/config.d/00-use-suspend-
  hybrid with the following contents:

  ---------- snip ---------------

  # Always use hibernate instead of suspend, but with "suspend to both"
  if [ "$METHOD" = "suspend" ]; then

  # Make sure to use the kernel's method, in case uswsusp is installed etc.
  ---------- snip ------------------

  On suspend, the system writes an image to disk (according to
  /var/log/syslog) and goes to sleep on RAM as expected. However, on
  resume things first seem to proceed normally, but the screen is never
  lit up. I couldn't find any obvious errors in /var/log/syslog.

  The behaviour is similar with the "Indirect hybrid sleep" approach,
  which used to work successfully before upgrading from 13.10 to 14.04.

  Both suspend-to-RAM and suspend-to-disk (hibernate) work and resume
  sucessfully, i.e. when removing the file /etc/pm/config.d/00-use-
