[Nicholas DiPiazza <nicholas.dipiazza@xxxxxxxxx>]

Sorry for the bother, but are there any plans to get this fix into
upstream on Ubuntu 14.x? This is the one thing holding many of us up
from upgrading and we are getting nervous because of End-of-Updates
coming so soon on Ubuntu 12.x.

Title:
  gnome-flashback (metacity) fails to start without hardware
  acceleration, cloud/remote environments
  (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting)

Status in “gnome-session” package in Ubuntu:
  In Progress

Bug description:
  When trying to launch gnome-flashback (metacity) session from
  XRDP/VNC/NX/X2GO/Chromoting it fails with diagnostics in log:

  >gnome-session-is-accelerated: No composite extension.
  >gnome-session-check-accelerated: Helper exited with code 256
  >gnome-session-is-accelerated: No composite extension.
  >gnome-session-check-accelerated: Helper exited with code 256
  >** (process:11622): WARNING **: software acceleration check failed: Child process exited with code 1

  When starting manually gnome-panel, metacity, nautilus and other
  components from .xsession - it works normally.

  Looks like - unnecessary check performed (and failed).

  This breaks gnome-flashback, breaking upgrade path from previous LTS
  and removing most sane option for cloud environments!
