I’ve been trying to get a fresh Ubuntu Mate 16.04 install to load the Mate Desktop from an X2go client. It loads the window for about a second then closes it. The logs report that the session has ended. No actual errors are reported. I installed the XFCE desktop and it works correctly without any issues. Any ideas?
Hi
I can confirm I’m having this problem too. Fresh install of Ubuntu MATE 16.04, updated and installed X2Go server. Tried automatic installation of the server from the Software Boutique and also command line installation from the ppa.
In all cases try to log in to a new MATE session (not an running one/desktop sharing) with an X2Go client from another Linux PC doesn’t work (exactly the same behaviour as stated in previous post). Big long dump from syslog with X2Go logging level set to debug below (if that gobbledy-gook means anything to anyone!).
I assume the problem is this line in the log:
Apr 24 22:01:14 Saturn org.a11y.atspi.Registry[12293]: XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":50"Desktop sharing by selecting “Connection to local desktop” session type works fine (but of course you need to already be logged in on the server which isn’t possible on remote machines).
Just to be sure, I also tried to install the X2Go sever on an different machine running Mint 17.3 MATE and in that case logging in to a new MATE session via a X2Go client works fine.
Full debug log:

No, me neither. I assume it’s caused by something new in 16.04 since it works in mint 17.3 mate which is based on 14.04 (haven’t tried with any distro based on 15.04 or 15.10). Just as an experiment I tried creating multiple parallel X sessions on the server attached to multiple VTs, to see if there was anything anything prevent multiple X sessions, and that worked fine. Anyway, I’ve given up try to find the cause, my knowledge of linux just isn’t deep enough.
Confirmed not working, found a bug report at x2go here http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1022
I tried the workaround in the 3rd message but that caused a lightdm login loop on my machine.
Yep, same for me --> lightdm login loop.
I managed to get Mate in 16.04 working by using system default value for
XDG_DATA_DIRS.
I set in .profile
export GSETTINGS_SCHEMA_DIR=/usr/share/mate:/usr/share/mate:/usr/local/share/:/usr/share/:/var/lib/snapd/desktop
export XDG_DATA_DIRS=/usr/share/mate:/usr/share/mate:/usr/local/share/:/usr/share/:/var/lib/snapd/desktop

From your solution I’m guessing it has something to do with the addition of Snap Packages in 16.04.
Thanks much, working perfectly now!
Yep, great it’s working!
