   (Imagen Combinada:3642) : Gtk-Warning **: cannot open display: localhost:10.0

resolvent

1. Method 1

sudo -E python myscript.py

Add -E Load after root In the user environment ~/.Xauthority
However, this method has certain security risks and is not recommended

2. Method 2

pi@RPi-Dev:~$ xauth list
RPi-Dev/unix:10  MIT-MAGIC-COOKIE-1  5cxxxxxxxxxxxxxxxxxxxxxxxxxxx3d3
pi@RPi-Dev:~$ sudo -s
root@RPi-Dev:/home/pi# xauth add RPi-Dev/unix:10  MIT-MAGIC-COOKIE-1  5c5cxxxxxxxxxxxxxxxxxxxxxxxxxxxd3

First use xauth list List all forwarding ports
Switch to a root user
Reuse xauth add Add the required ports
Because the error reported above is localhost:10.0, So what's added here is RPi-Dev/unix:10

Gtk-Warning **: cannot open display: localhost:10.0

After adding, you can not add -E The direct operation succeeded
