You're right, here are what you asked, all taken from the TCE directly, not from within the X2Go session :

========================================================================= root@TCE-CLIENT-DELL-VOSTRO430-4D1ZR4J:~# xdpyinfo -display :0

No, that's wrong!

xdpyinfo -ext XINERAMA -display :0 is the right command!

========================================================================= root@TCE-CLIENT-DELL-VOSTRO430-4D1ZR4J:~# xrandr --display :0 Screen 0: minimum 320 x 200, current 3840 x 1080, maximum 8192 x 8192 DVI-I-1 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 510mm x 287mm 1920x1080 60.00*+ 1280x1024 75.02 60.02 1152x864 75.00 1024x768 75.08 60.00 800x600 75.00 60.32 640x480 75.00 60.00 720x400 70.08 HDMI-1 disconnected (normal left inverted right x axis y axis) VGA-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 287mm 1920x1080 60.00*+ 1280x1024 75.02 60.02 1152x864 75.00 1024x768 75.08 60.00 800x600 75.00 60.32 640x480 75.00 60.00 720x400 70.08

So I expect the correct command to report 2 heads, one with 1920x1080+1920+0 and one with 1920x1080+0+0

If that is not the case we have the reason for the problems.
