[Michael Plotkin <plotkin@xxxxxxx>]

Hello,

I'm sorry to bother, I know that practically the same question was asked
a few months ago by Nicholas DiPiazza, but it wasn't directly answered.
- Is there any time frame to fix this problem in the "official"
distribution of "Trusty"? Similarly to what was said previously - this
is the main reason we cannot upgrade to 14.04 from 12.04. It's
absolutely critical for us to use remote sessions using NX (or any other
method to have remote gnome session that would provide speed as good as
NX does).

Thank you,
Michael.

Status in The GNOME 2 Session Manager:
  New
Status in “gnome-session” package in Ubuntu:
  Triaged

Bug description:
  This bug will cause static grey or black screen instead of openning
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

  3) What is expected to happen is when one installs xrdp on the host
  and attempts to use remmina or vinagre on a Ubuntu 14.04 client to RDP
  in, it works.

  4) What happens instead is it shows a gray static screen as per attached screenshot. This would appear an issue with gnome-session as per client log:
