What if the Image Window doesn't refresh correctly under x2go ?
https://wiki.x2go.org/doku.php X2go is based on an old version of the NoMachine NX libraries. These had a bug which must be worked around.
You may have try adding an option to /etc/x2go/x2goagent.options ; earlier versions of the NX software required the following addition to /usr/NX/etc/node.cfg :
AgentExtraOptions="-defer 0"
Finally, try using "adxv -nopixmap"

Visualizing XDS data reduction
ADXV can read spot files (whose name ends with .adx) and display them together with the frames.
These spot files can be written by generate_adx. In adxv's file selection window, it is useful to change the filename pattern from e.g. "*.cbf" to just "*" which then gives you the possibility to load frames and spot files at will.
If using ADXV on a NoMachine (NX) desktop, it is useful to know that one needs the -nopixmap commandline option if the frame is not correctly displayed (I found that the zoom window still does not display correctly).
