PinePhone. How to run Python/Tkinter app?

[Manieck71]

Running a standalone X11 session is a bad idea on the PinePhone. Phosh does not support it (and neither does Plasma Mobile). There is SXMO which supports X11, but since you write you are a beginner to GNU/Linux, I doubt you will want to use that (and I also think it is not supported by Mobian).

Instead, you will want to use XWayland (apt install xwayland) in the Wayland session. (You should not have to do anything beyond installing the package. It should get autostarted if it is installed.)

I did

Code:

sudo apt update
sudo apt upgrade
sudo apt install xwayland

Reading package lists... Done

Building dependency tree... Done
Reading state information... Done
xwayland is already the newest version (2:23.2.0-1).

How can I now use XWayland to run a python program?
