FYI: I have made a patch for nx-libs that fixes some BIG-REQUESTS
problems (atom and vscode now work). It does not seem to help with
paraview 4.4 but I also cannot properly use it without x2go, I get
"Cannot mix incompatible Qt library (version 0x40807) with this
library (version 0x40806)". So YMMV.

Here's the patch: https://github.com/ArcticaProject/nx-libs/pull/729
(not sure when it will make into the released code. For now you have
to apply and compile yourself
