Xming clipboard only works one way

I recently started using Xming to display-back X11 applications from a Linux VM to my Win XP desktop. It's great -- much more useful than the solution I had before, which used VNC -- but the clipboard behavior is wonky.

At first, I couldn't get the clipboard to sync at all. I killed and restarted Xming a couple of times, and now it's consistent (but wrong):

• When I copy in Windows, I can paste in Linux or Windows.
• When I copy in Linux, I can paste in Linux but not Windows.
• When I copy in Windows, then select in Linux, the primary (selection) and secondary (CTRL-C) buffers both work fine in Linux, but pasting in Windows doesn't work.

Note that when I say pasting in Windows "doesn't work", the Paste menu item is available, indicating Windows thinks there's something on the clipboard, but nothing gets pasted.

In X-Launch, “Clipboard – Primary Selection – Also map the PRIMARY selection to the Windows clipboard”, uncheck it.

You could try VcXsrv if you are using the public domain version of Xming (6.9.0.31).

I've just discovered VcXsrv and in my quick test copy/paste works perfectly between Linux and Windows both ways. (Ubuntu 12.04 xterm, emacs and Windows XP)

Using the "public domain release" Release: 6.9.0.31 it turned out that turning on the -nodecoration option, allowed the clipboard from linux to be shared to windows

Using git-bash:

$ export PATH=$PATH:</path/to/Xming/>
$ Xming :0 -multiwindow -clipboard -nodecoration & 
$ ssh -Y <hostname> "gnome-terminal"

I could then highlight text inside the terminal window, and paste it around windows :)

Using VcXsrv version 1.20.8.1 (7 Apr 2020), installed via Chocolatey:

1. right click on the XLaunch icon in the taskbar

2. unselect Clipboard may use PRIMARY selection
