树莓派 Tkinter 通过 shh 和 xming [英] Raspberry Pi Tkinter via shh and xming

问题描述

我正在尝试通过 ssh 客户端和 xming 从树莓派运行 Tkinter 脚本.通过 shh 登录 pi 后，我使用以下命令:

I'm trying to run a Tkinter script from a raspberry, via an ssh client and xming. Once I've logged into the pi via shh I use the command:

gksudo python3 home/pi/PythonScripts/TkinterTest.py

这是在我的电脑上给出的错误:

This is the error that is given on my PC:

(gksudo:2700): Gtk-WARNING **: cannot open display:

在我的笔记本电脑上运行相同的软件时出现不同的错误:

and a different error on my laptop running the same software:

(gksudo:3227): GLib-CRITICAL **: g_str_has_prefix: assertion 'str != NULL' failed

我尝试使用以下命令更改显示:

I have tried to change the display with the command:

export DISPLAY=:0.0    

但这对输出没有影响.

推荐答案

1. 首先确保X转发在您的树莓派上处于活动状态，您可以在/etc/ssh/sshd_config中检查:X11Forwarding yes
2. ssh -X username@(X11 转发的 -X 标志)
3. 运行你的脚本:(su) python/path/to/script.py

1. First of all be sure that the X forwarding is actived on your raspberry, you can check that in /etc/ssh/sshd_config: X11Forwarding yes
2. ssh -X username@<raspberry> (-X flag for the X11 forwarding)
3. Run your script : (su) python /path/to/script.py

有时当您尝试通过 sudo 运行程序时会出现一些错误，您需要检查 .Xauthority 文件的权限

Sometimes when you try to run program via sudo you can have some error, you need to check the permissions of .Xauthority file
