Hello Brian,

Thank you for the quick reply. I have gnome-flashback installed, but I don't know how to trigger it from x2go. When I log in from VNC into a gnome flashback session and do "ps aux" to find out the command that triggered the session, I see this:

gnome-session --session=gnome-fallback

If I use this in x2go, I end up with the same black screen I get when I try the 3D enabled desktops (Unity and GNOME). Is there anything else I need to do to make this work?

Best Regards, Nikos

Gnome Flashback is a session for Gnome 3 which was initially called "Gnome Fallback", and shipped as a stand-alone session in Debian and Ubuntu.

It provides a similar user experience to the Gnome 2.x series sessions.

It consists of the following components:

• GnomePanel
• Metacity
• GnomeApplets

The first release was on 2013-09-25, included in gnome-panel 3.8.0.

This is the first release that ships a session descriptor and wrapper script for the "Gnome Flashback" session.

This is similar to the standalone fallback session previously shipped in Debian / Ubuntu.

As integration with the rest of the Gnome stack has suffered somewhat, this is mainly aimed at distributions that still want to support a metacity / gnome-panel based desktop (e.g. for LTSP installations).

Some integration work may be necessary - for example, nautilus 3.8 no longer draws the desktop background icons.
