Set Transmission as default program when opening magnet links

Question

How can I set up Chromium to open Transmission when clicking on a magnet link such as on TPB?

Chromium says that it will use xdg-open but that generally doesn't do anything

System: Manjaro Linux 0.8.5.2 fully upated

Desktop Environment: Xfce 4.10

Solution

Chromium obeys the system-wide xdg settings. To configure opening magnet links with a custom application use the following command

xdg-mime default transmission-gtk.desktop x-scheme-handler/magnet

You can also do this manually: Open the file ~/.local/share/applications/mimeapps.list and add the following entry in the section [Default Applications]:

x-scheme-handler/magnet=transmission-gtk.desktop

You can confirm the new setting with

xdg-mime query default x-scheme-handler/magnet

Xfce hardly any settings have been changed from default

I did that however I still get 'Unable to to detect URI-scheme of'

@abacusasian What does the last command from my answer return?

@Marco, I tried your steps and although I get transmission-gtk.desktop as output from the xdg-mime command, nothing happens when I click on a magnet link in chrome.

@Marco 'transmission-gtk.desktop'

@Marco I have the same problem abacusasian has, and your solution did not work :(

ran this method in Ubuntu 18.04 LXDE and works perfectly altho the Open xdg-open popup still appears but when I click on it it DOES open in Transmission now ... so thank you Thought of the addendum here as many might see the pop-up and think nothing has changed
