libX11.so.6 error

[Francesco Pietra <chiendarret@gmail.com>]

Resent inserting the subjet

While attempting to create a virtual scree with the remote cluster, the error arose:

/loader/pyi_importers.py", line 409, in load_module
ImportError: /usr/lib/x86_64-linux-gnu/libX11.so.6: undefined symbol: xcb_poll_for_reply64

I am at debaian9 amd64. No problem with local graphiocs.

Thasnks for advice
