Niri WM support about flameshot HOT 1 OPEN

It's weird that you get this error, looking at the code I don't see any way a Wayland WM can get to the stage where it prints that error. Worst case scenario your DE should be set as "OTHER" in the code, and you should get a warning about having grim installed.

Maybe try setting your XDG_CURRENT_DESKTOP environment variable to something like "niri" or "niriwm" first, if it's unset.

Adding a WM to the code is actually easy, you just need to modify desktopinfo and screengrabber. But there's some other issue here.

If you want to debug the code yourself, add the following statements to ScreenGrabber::grabEntireDesktop just before the switch statement:

        auto wm = m_info.windowManager();
        AbstractLogger::info() << tr("Detected window manager: %1").arg(static_cast<int>(wm));
        
        switch (wm) { // Change the existing switch statement to this

You should get a number between 0 and 5, each corresponding to an enum value in desktopinfo.h.
