_tkinter.TclError: couldn't connect to display ":10.0"

When remoting in and trying to run the program I get the above error. I solved it using THIS post.

Run sudo cp ~pi/.Xauthority ~root/ in the terminal. Then CommanderPi starts as expected.

Hmm, try with new version of CommanderPi

nikescar1 commented 4 years ago

It's not a problem with your program, it has to do with tkinter not finding the display because of some sort of X11 display permissions.

Also, I fixed the link in my original post. That should better explain the issue since I don't know much about linux or python libraries.

Ok so I close issue

Seems you have to run that command on every reboot. Very annoying.
