For Xming I found this with Google, which points to our forum here
Export Display Through Telnet & Xming
... and this one could be also helpful for you:
Cannot connect to Cygwin or XMing from Debian SSH session
For X/Cygwin:
Cygwin is a complete Linux like environment for Windows with shells, tools etc.. X is just a part of it while there is a kind of distribution being called "X/Cygwin" of Cygwin available too.
I got the "normal" plain Cygwin installed. For this I have downloaded the setup.exe from
Cygwin and did nearly a plain install but the fact, that I added following things in the X11 folder you see when executing the setup in some step:
- xorg-server
- xorg-scripts
- xhost
- xterm
- X-start-menu-icons
- All packages that started with "font..."
After the installation there is for example D:\cygwin\bin\startxwin.exe which I just have as a link on my desktop. When I start it, a xterm is opened and I enter
xhost+. That's all and I then go to the remote host where I want to start the Xapplication, export the DISPLAY with the Win-box as target as you did.
