screeninfo failing to parse monitors if they have been modified

[tahlonbrahic]

I am on Hyprland, btw, and I have noticed that screeninfo is failing to properly parse my monitors if/when they are modified through an application like nwg-displays

If you run screeninfo in a separate project and call the get_monitors you receive and error such as the following.

[tahlon@yoru:~/projects/python/testScreeninfo]$ python ./testScreeninfo/__main__.py Traceback (most recent call last): File "/home/tahlon/projects/python/testScreeninfo/./testScreeninfo/__main__.py", line 4, in <module> MONITOR_OPTIONS: List[str] = [m.name for m in get_monitors()] ^^^^^^^^^^^^^^ File "/nix/store/sx3m1039r9n7brrb0799px6v3hh62qqp-python3-3.12.10-env/lib/python3.12/site-packages/screeninfo/screeninfo.py", line 32, in get_monitors raise ScreenInfoError("No enumerators available") screeninfo.common.ScreenInfoError: No enumerators available

I believe the same thing is happening in waypaper and it is monitors to display a wallpaper in their original resolution / position as everything works well without modifying those properties.

I have looked on the screeninfo GitHub and noticed that several other people experience this issue and that it has not been fixed in several years.

Would it be possible to look into another package to pull current monitors OR allow them to be specifically configured as an option.

I would be happy to make a pull request.

Thank you for reporting.
Yes, I actually have been looking for a while to get rid of the screeninfo, because it also often has packaging issues. Here is the deal:

• With hyprpaper (on hyprland), it's easy, we can use hyprctl to get monitor info.
• With swww, it's easy, we can use swww-deamon to get the monitor info.
• With all other backends, there's no easy way to get monitor info, plus it has to work on x11 as well.

Unless you know a reliable way to get monitor info, I'd say, we should implement a check that if we are on those two backends, we use their built-in functions, which maybe covers most users. Otherwise, we attempt to import and use screeninfo.get_monitors().

p.s. there's a method implemented in Azote to check the monitors, but it's a pretty complex tree of possibilities, which I'd like to avoid, that's why so far screeninfo was the solution.
