Yes, these are fixes for the nxagent which runs on the Linux side (as x2goagent). Uli ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user
Re: [X2Go-User] clipboard stopped working (again)
Thanks for the detailed explanation. For my use of x2go, I need both clipboards to work correctly. I will try to find time to test your new version. A few questions: 1) I'm guessing I will need to clone your branch and build the new version from source? No binary builds available? 2) Are your changes related to the Linux side only? No changes on the Windows end? Norm On 10/29/2020 2:05 AM, Ulrich Sibiller wrote: Well, in X11 (and therefore x2go resp. NX) there two clipboards, PRIMARY and CLIPBOARD.

Re: [X2Go-User] clipboard stopped working (again)
Well, in X11 (and therefore x2go resp. NX) there two clipboards, PRIMARY and CLIPBOARD. PRIMARY is the one that gets used when you mark some text and paste it with the middle mouse button. CLIPBOARD is the one that gets used by explicitly issuing a "copy" or "paste" command, e.g. in the menu of konsole. In Windows we only have one clipboard which works like the aforementioned clipboard. In order to have both X11 clipboards on windows vcxsrv offers to join them.
