Multi monitor doesn't work, throws an error #75

Open lululock71 opened 4 years ago

Hi, I wanted to experiment (again) with multi monitor setup to finally get it to work, after the latest update of the .py file. But it doesn't work.

My current setup :

Hi @lululock71 I tried with python 3.8 and it doesn't work, neither with python3.7. I must investigate that, but for now the fastest solution for you and for now is to use it with python 3.6. Two easy steps:

  1. `sudo apt install python-3.6'
  2. and then change the first line of your copy of the script for: #!/usr/bin/env python3.6

This actualy gives me more confidence regarding what I was deciding lately about rewriting this whole project in Rust, refactoring to make it more reliable and maintainable... Leaving python behind would make me very happy... I think this may be the time to do it.

lululock71 commented 4 years ago

I'm on Arch, so my Python interpreter is always updated to the latest version and 3.6 is only available in AUR. I will not use multi monitor for now. It always been broken anyway...

Rust is an awesome and reliable language but why not C ? More people would be capable of helping and the development will be faster... Are you sure that the advantages brought by Rust over C will make the difference for this quite small project ? Also, C compilers are more robust and reliable nowadays.

Honestly, mainly because after learning Rust and enjoying its features and ecosystem for a while now, I no longer desire to program in any other language for the next 50 years :smile: Otherwise I really can't see myself keeping motivated to maintain this neither in python, C, haskell, go or whatever. And if I use the language I'm most comfortable with, and have fun doing it, it will only lead to good things. Also its future is bright.

I also believe it's sufficiently mature right now for this task and more. Even providing it of a simple GUI. But for now I'm gonna just try to recreate the current functionality in a more sensible way.

  • I can't import the evdev module anymore in python3.7 or greater. My error is different than yours and I don't know if it's all system dependent, but this kind of things shouldn't happen, nor the bugs people have in their different OSes due to the unreliability of the python ecosystem configuration...

I have no problem import evdev into python 3.8.2

Python 3.8.2 (default, Apr 27 2020, 15:53:34) 
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import evdev

on ubuntu 20.04

lululock71 commented 4 years ago

I think it depends on the distro you're using. It's working under Ubuntu but on Arch, the module location might be different, hence that error. It's completely system dependent.

That's why the script should be able to detect the location of the module, before trying to load it.
