I have an issue with xrdp being unable to display gnome fallback session in 13.10 - connection works fine but everything I get is Xserver grey screen and X cursor.

My hardware config is ATI HDMI with dual display on ATI drivers.

What I have done until now:

  • Installed xrdp (no tightvnc), gnome-session-fallback from terminal.
  • Created .xsession file in my home dir:
  • gnome-session --session=gnome-fallback
  • Restarted xrdp several times, restarted Ubuntu

At the moment file is owned by the user I am trying to connect as and has executable privilegs.

What I get after connection from Windows 8.1 laptop is Xserver grey desktop and no chance to play.

.xsession-errors says:

Xsession: Xsession started for at ....

X error of failed req: BadValue (Integer param out of range)

Major opcode for failed req: 109 (X_changeHosts)

Value in failed req: 0x5


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

I have already reinstalled system like 20 time to solve some issues but being unable to RDP is a no go for me.

When I installed xfce4 it was working fine. What's wrong with my gnome-fallback?

It was not fixed in 14.04. Perhaps this is due to my upgrading from12.04. I will try it with a fresh install ... one day. – Reinier Post Aug 23 '15 at 20:12

Gnome-fallback package seems to be broken.... You could still use xrdp if you install an alternative desktop environment.. We have installed xfce desktop instead of gnome-fallback and we can perform xrdp connection to Ubuntu 13.10

a good explanation can be found at

might be a good idea to fill in a bug report for xrdp, gnome-fallback and Ubuntu 13.10

For people using vnc software, they might encounter the same issue... Same solution here, need to install xfce and have the ./vnc/.Xstartup file modified in order to use the xfce desktop... inside the file add something like startxfce4 &

Hope this help

Thank you for letting me know that! I spend hours pointlessly trying to get it to work. The strange thing is that the gnome flashback works from the ubuntu machine, but does not from xrdp. I didn't want to use xfce4 as I read somewhere it is not a best idea to mix desktop environments on one system. Do you think that maybe there are some PPAs with gnome session fallback more recent builds (fixed)? I kind of like this env and xfce4 is not really my type ;-) Thanks Adam – user208193 Oct 27 '13 at 13:28
So, my question is that if I use fce instead and the bug is fixed... how do I go back?? – ITB-GTI-10 Jan 4 '14 at 14:51
Is there any way to do this without using xfce? it's not as good as unity – Jason Jan 21 '14 at 23:18
ermagawd i thought it was something I broke..... lemme try xfce – Peng Tuck Kwok Jan 24 '14 at 7:08
