Sorry that you are running into the issue.
1st of all, because you are on Ubuntu 14.04, it would be easiest if
you would use a desktop environment other than GNOME3 or UNITY. KDE,
XFCE and LXDE are included in Ubuntu 14.04 and work fine with X2Go.
You can also install MATE (the fork of GNOME2) from
http://mate-desktop.org/ . There are other desktop environments that I
However, it is possible to make GNOME3 work on Ubuntu 14.04. GNOME3
will use gnome-panel, not gnome-shell. There will also be bugs. For
example, the desktop wallpaper does not show up
The email is not showing up on lists.x2go.org or gmane.org, but Eugene
San sent the email forwarded below with the currently available fix
His email is written from a developer's perspective. So below are user
instructions I just wrote that you can follow.
1. Add this PPA:
2. Install all available updates from the PPA (if need be, I can
narrow down which exact packages you need to update.)
3. Install the following packages:
gnome-panel gnome-applets gnome-session-flashback
4. create the file /usr/local/bin/gnome-flashback.sh with the
5. Make that file executable
6. In X2Go Client's session preferences, specify a "custom desktop"
with the following "command":
Steps 1-2 are due to a bug in Ubuntu that we hope to fix soon. (The
bug is that gnome-session checks for 3D acceleration, even though
gnome-flashback doesn't require it.)
Step 3 will be required until we develop an easier solution for
installing those packages. We are thinking of creating a metapackage
that depends on them.
Steps 4-6 are due to a bug in x2goserver that has already been fixed
in our git repo. When x2goserver 220.127.116.11 is released, it will contain
the fix, and you will merely need to select "GNOME" as the session
type in X2Go Client instead.

Reading Michael's message and Andrew's article
inspired me to attempt to revive gnome-fallback (flashback) using x2go
Few hours later I have a solution.
In addition to packages I was maintaining previously, I had to port
and tweak, two more packages from gnome 3.12: gnome-desktop3 and
You can find them at my PPA: https://launchpad.net/~eugenesan/+archive/ppa
To mimic full unity-2d scheme, please follow instructions in article:
In addition to instructions in article perform next:
1. Install gnome-applets-window and add it's applet to panel.
2. Install metacity and disable window decoration in full screen by
invoking: gsettings set org.gnome.metacity show-maximized-titlebars
Note, there are some minor visual glitches, at which I might look later.
There is also a minor change to x2goruncommand:
