  System sleeps at GDM prompt even when told not to

Status in “linux” package in Ubuntu:

Bug description:
  After upgrading to 14.04, my Dell Dimension E521 sleeps at the GDM
  login window after a short amount of time. But I have used the System
  Settings -> Power Management -> Energy Saving panel to tell it never
  to Suspend Session.  I have Screen Energy Saving set to 10 minutes.  I
  have tried many different settings based on recommendations found on
  the web, but no matter what, the system sleeps at the GDM login window
  after a short amount of time.

  I'm using Kubuntu, running KDE, not that horrible Ubuntu interface for
  tablet users.

  This sleep behavior causes two problems:

  1) The system goes to sleep and never wakes up, but that is the
  subject of a different bug.

  2) If the system reboots for any reason, it then promptly goes to
  sleep, which means that it is essentially down, and then I cannot
  access it remotely. And I access it remotely quite often. I rely on my
  system being up and accessible, and this bug prevents me from using
  the system after it reboots.  For example, if the power goes out at my
  house (which it does).  I have the BIOS set to reboot after power
  loss, but then the system goes to sleep.

  So, how do I tell my system NOT to go to sleep while waiting for login
  at the GDM window?  Why do the Power Management settings appear to do
  nothing at the GDM window?  How do I configure the GDM window sleep
