commanaderPi won't start. I have the same problem, installed ok and have the CommanderPi logo on the desktop, but if you run it, it will not show the CommanderPi window. I believe there is a path issue on my setup. On this set up, I need to enter password on any sudo type commands. Will it cost an issue on your code? Thanks.

Are you using Raspberry Pi 4? What is your path to CommanderPi and did you installed it as user not root?

[midengc8]

yes, using a Raspberry Pi 4. Path is Home/Pi/CommanderPi. I have Octoprint running also.

[Jack477]

Type this in terminal and tell me what you see sudo python3 ${HOME}/CommanderPi/src/main.py ${HOME}

[midengc8]

pi@octopi:~/CommanderPi $ sudo python3 ${HOME}/CommanderPi/src/main.py ${HOME} [sudo] password for pi: Traceback (most recent call last): File "/home/pi/CommanderPi/src/main.py", line 9, in import gui as g File "/home/pi/CommanderPi/src/gui.py", line 4, in import resources as rs File "/home/pi/CommanderPi/src/resources.py", line 5, in import psutil ModuleNotFoundError: No module named 'psutil'

[Jack477]

Install this module with pip install psutil

[midengc8]

Installed, but looks like still missing, CommanderPi still not working, same as before. Please look at the following : Need in a different path? Thanks for the help.

pi@octopi:~/CommanderPi $ pip install psutil Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple Requirement already satisfied: psutil in /usr/local/lib/python2.7/dist-packages (5.7.3) pi@octopi:~/CommanderPi $ sudo python3 ${HOME}/CommanderPi/src/main.py ${HOME} Traceback (most recent call last): File "/home/pi/CommanderPi/src/main.py", line 9, in import gui as g File "/home/pi/CommanderPi/src/gui.py", line 4, in import resources as rs File "/home/pi/CommanderPi/src/resources.py", line 5, in import psutil ModuleNotFoundError: No module named 'psutil'

Perhaps "pip3 install psutil"?

[midengc8]

Still the same, no psutil module. not sure what is going on.

[midengc8]

I tried to import psutil directly, this is what I got: pi@octopi:~/.local/lib/python3.7/site-packages/psutil $ import psutil

import-im6.q16: attempt to perform an operation not allowed by the security policy `PS' @ error/constitute.c/IsCoderAuthorized/408.

Any idea what is going on here? I am not too well verse on Linux.

[Jack477]

What OS are you using?

[midengc8]

Raspberry Pi OS with desktop. I also installed octoprint.

[Whiskaya]

I struggled with this for like half an hour until I read the readme.txt file. Did you run install.sh AFTER you moved the CommanderPi folder from Downloads to your Home folder? At least this was my mistake, and it worked right away.

[midengc8]

Did all of those, same thing. The interesting part is that when I do not have Octoprint in the built, CommanderPi works. I wonder what is causing the problem with Octoprint.

Hi, It doesn't seem to like Sparky Linux. Maybe it shouldn't but most other Pi apps do....so far ;-)

[gprime31]

Ya, it's still needs Sudo to run, extract it in /home/pi/ Then: ./install.sh (non Sudo) then cd /home/pi/ComamanderPi/src. Then run sudo ./start.sh from terminal, if you don't run sudo it will ask anyway, works fine, just don't use desktop shortcut.

Here is what I get: pi@raspberrypi:~ $ sudo python3 ${HOME}/CommanderPi/src/main.py ${HOME} Here is home_path /home/pi Here is app-1 Version 1.0 Exist and read Country code is: country DE: DFS-ETSI Here is ad: pieeprom-2021-12-02.bin Apr 29 2021 /home/pi/CommanderPi/src File is exist! path is /home/pi/CommanderPi/src No protocol specified No protocol specified Traceback (most recent call last): File "/home/pi/CommanderPi/src/main.py", line 26, in main() File "/home/pi/CommanderPi/src/main.py", line 22, in main start = g.Window() File "/home/pi/CommanderPi/src/gui.py", line 673, in init master = tk.Tk() File "/usr/lib/python3.7/tkinter/init.py", line 2023, in init self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) _tkinter.TclError: couldn't connect to display ":10.0"

The two last lines seem to indicate the app can't access the display: but when I double click on the CommanderPi icon I get the "Execute File" menu. But the buttons don't work.

Here is my output - as suspected the culprit is the ongoing rdp session which holds display 10 already. When executed directly on the desktop it works fine.
