Hi,
Is there an issue with the clipboard between a Windows client (v4.1.2.0) using the integrated X-Server and a connection to a local desktop on a Linux server (v4.1.0.3)?
Whatever I tried, I wasn't able to copy or paste any data between them.
What am I supposed to exactly do to use the clipboard? It is set up for bidirectional copy and paste, btw.
Ingo
There a occasional problems with clipboard when using Windows. This is most like a bug in the Vcxsrv we ship which has not been identified yet. However, I never heard of the clipboard not working at all.
You could try using the built-in Xserver of Mobaxterm and check if the problems persist.

So I guess I'm supposed to simply do an Edit->Copy in the server session window of - let's say - Linux' Leadpad and an Edit->Paste in Windows' native Notepad then, for example? Does not work.

I'm using this one.
Trying to use the shipped Vcxsrv results in a client start-up error ("Can't start X.Org-Server. Please check your installation.") which immediately shuts down the client disabling to change the setting again. :-(
After fixing this problem in the registry (wrong default path to vcxsrv.exe by the installation routine) the problem persists. Clipboard does not work.

Hmm, maybe clipboard is disabled in /etc/x2go/x2goagent.options. Please check!

What path did the installer put into the registry?
Another question: do you run some kind of clipboard manager on Linux and/or Windows?

You did notice that he said he's trying to mirror a physical display, right? Was clipboard sharing ever supported there? I don't think so ...

Sorry, I missed that. Well, I don't know if it is supported there. Must check.

How would you even keep 4 clipboards (User's client, actual X2Go session, support person's client, shadow X2Go Session) in sync? Sounds like a nightmare to begin with.

The same way FLOSS syncthing keeps a text file in sync across N different systems, OSs, etc? I mean, it's usually a specialized product, but being as both are FLOSS, I guess someone could spend time to integrate either the tech just for clipboard, or hack something together with a text file that is synced and then the X2Go client puts whatevers in the text file into the clipboard on the computer it's running on?
Of course, that's a lot of work, and I'm just being slightly flippant.
I often work around clipboard sync issues (hello freerdp) with a shared text file that I overwrite wherever and then copy paste "locally".

Yes, xfreerdp is constantly breaking clipboard...
Having such a second clipboard sync mechanism looks easy at first glance. But you somehow need to integrate with existing clipboard, and that's where the problems begin (again).

Well, in principle it is simple. I reality it's not. The problems are manyfold: them somehow which - in the past - proved to go wrong sometimes.
- there are several types of clipboard (PRIMARY, CLIPBOARD, CutBuffers). Not all platforms support all types. So you have to sync
- there are differences in the type of clipboard content that can be handled on different platforms
- we have not yet included the INCR message type yet so the maximum clipboard size is currently limited
- clipboard managers offten disturb the communication at some point. Some platforms and frameworks include clipboard managers that cannot be disabled
- bugs in X servers do not help
- debugging is difficult/complicated as always multiple windows/clipboard owners are involved
- there's also a multi-stage protocol between nxagent and nxproxy for clipboard transfer
- understanding the existing clipboard code is complicated.
Anyone is invited to help here!

X2GO_NXAGENT_DEFAULT_OPTIONS+=" -clipboard both" was commented, but no change after activating it.
What path did the installer put into the registry?
C:/Program Files/VcXsrv/vcxsrv.exe, but my installation is in C:/Program Files/x2goclient/ and thus vcxsrv.exe in C:/Program Files/x2goclient/VcXsrv/. (I don't remember whether I changed the installation directory (probably not) or whether it's the default anyway.)

Nope. Pure X and Windows.

Please let us know which edition of Windows you are using, the drive/directory where you *tried* to install X2GoClient, and the drive/directory where X2GoClient believed it would find VcXsrv.

A common problem I see is that when I copy and paste from the Linux side (Fedora 28-29) and then paste into Windows 10, I get chinese characters. Which makes me think it's a UTF8 mismatch somewhere.

I'll see what I can do next week when I find the time.
