Exact steps to reproduce the issue

Pre-steps:

• Have chromium installed;
• Have nnn installed.
• Have an image viewer like sxiv or feh installed.
• Set sxiv or feh as the default application to open images.

1. Open nnn version 3.1.1 (latests on archlinux repository);
2. Navigate to a directory containing a .png;
3. Press enter on the .png
4. Chromium should open the png.
5. Go to another file manager (like nemo, or nautilus);
6. Double click the .png, it should open with sxiv or feh (previously set as default)

Issue I'm having is described in steps above. What I was trying to accomplish was to open images with sxiv in nnn, and it is already as the system default application.

not sure if this is a local bug, but maybe I would need to setup a custom application on nnn for this. Any additional debugging steps would be nice.

See xdg-open(1) and xdg-mime(1). I have a very similar system and the images are opened in sxiv as expected.

[deadpyxel]

I did some digging, it seems that xdg-open is defaulting to chromium for opening image/png. Does this mean I have to configure it?

[KlzXS]

Yes. Use xdg-mime default application mimetype(s) to set default openers for mimetypes. In your case application would be sxiv.desktop.

[deadpyxel]

That did the trick. Thanks for the explanation.

Also thanks jarun for closing it quickly. Sorry for mistaking this for a bug.

No problem!
