When the 3D viewing software paraview is executed in a x2go session, it does not start, but yields the error below: $ paraview X Error: BadLength (poly request too large or internal Xlib length error) 16 Major opcode: 18 (X_ChangeProperty) Resource id: 0x30001da This problem does not appear in older versions of x2go. I could not find a workaround for the problem. Any hints are welcome. OS: Ubuntu 16.04 Xenial Paraview - Version 4.4.0 NXAGENT - Version 3.5.99.16

Hi Uli,
ok, when I put
X2GO_NXAGENT_DEFAULT_OPTIONS+=" +extension BIG-REQUESTS"
into /etc/x2go/x2goagent.options then paraview starts without errors.
But the comment says: "Disable BIG-REQUESTS, nx-libs does not implement this extension correctly. Leads to all sorts of weird crashes if left enabled." Is this still true? Do I have to fear all sorts of weird crashes?

Yes, unfortunately this is still true. I am unsure what exactly the problems are. But we have apps that crash with the extension enabled. And we have some apps that crash with the extension disabled ;-(

Dear Uli,
thanks for the information.
I will continue with the BIG-REQUEST enabled and see how it works.
I would like to add that the problem appears since an update a few weeks ago (the software was installed through the x2go-stable repo from launchpad). Before that, everything worked fine. Is it possible to trace the change which lead to this problem?
Regards, Hannes

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

You don't have to fear anything, if it works with BIG-REQUESTS then it just works (mostly). This is just that, as Uli said, the BIG_REQUEST extension support is very buggy in NX and thus, some apps work with it (or even need it to work such as VLC or your 3D viewer) and some don't (such as ATOM.io, VSCode and many other elektron based applications).
By now, depending on your needs, you should enable it or not.
