Doesn't work on Fedora 42 / GNOME 48

[yioannides]

Hello, thank you for your great work!

I've been trying to use your Python script in Blender 5.0 (flatpak) and it doesn't seem to be able to pick up my system scheme. I do get a manual output for def get_current_mode(context) in my IDE (after installing darkdetect via pip), but Blender only seems to detect System Appearance Mode: Light. Not sure if something changed in the Blender API since 1.0.1 or not... If I missed something, please let me know!

The filesystem=host override is enabled by default, but I also added filesystem=home for good measure, but that didn't seem to do anything either.

Thank you!

I found this open issue stating that the darkdetect library has trouble detecting dark mode in GNOME: albertosottile/darkdetect#43

As mentioned above, it worked when pressed for a manual output in my IDE, but also tried the following function just in case:

import subprocess

def test():

    output = subprocess.run(
        "gsettings get org.gnome.desktop.interface 'color-scheme'",
        shell=True,
        capture_output=True,
        text=True,
        timeout=5
    )
    
    result = output.stdout.strip().strip("'\"")
    
    if 'prefer-dark' in result.lower():
        scheme = 'Dark'
    elif 'default' in result.lower():
        scheme = 'Light'

    return scheme

While I do get an output from this function and from the original function, I'm not sure what happens in def set_theme_from_system(context) and how it relates to Fedora, GNOME or Wayland.
