I am trying to start and X11 connection from my remote Linux server to my Local Windows machine.

I've downloaded Xming portable and if I start an ssh connection to my Linux machine and starts Firefox it is passed to Xming and shown on my Windows machine.

I have now tried to achieve the same in python. But I do not think I understand it correctly.

I'm using the following code 

import paramiko
import time

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('server-1', username='me', password='xxxxxxx')
stdin, stdout, stderr = ssh.exec_command("firefox")

t = ssh.get_transport ()
chan = t.open_session ()
print(chan.request_x11())

print(stdout.readlines(), stderr.readlines())

time.sleep(100)

only to get the following error: 

 Error: GDK_BACKEND does not match available displays

I've also read that python it self can start and Xll session. But for now I only need it to be forwarded to my Xming server.

I only understand the very basic of what an X11 connection does and all the examples I've seen here is for when the python script is running on Linux.

我自己想通了。虽然我不完全了解细节，但我猜 Xming 必须连接到 SSH 套接字或其他东西。无论如何，我需要做的就是将我的命令更改为以下

stdin, stdout, stderr = ssh.exec_command("export DISPLAY=localhost:10.0; xterm & firefox &")

Firefox 在 Xming 中打开。另请注意，python 脚本在此处被阻止，直到 Firefox 应用程序再次关闭。

所以我的最终代码如下

import paramiko

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('server-1', username='me', password='xxxx')
stdin, stdout, stderr = ssh.exec_command("export DISPLAY=localhost:10.0; xterm & firefox & env")


print(''.join(stdout.readlines()), ''.join(stderr.readlines()))

ssh.close()

由于 Xming 是一个命令行应用程序，它也应该可以从 Python 应用程序内部启动。
