Setting the default program that Chrome / Chromium uses to open links in Ubuntu is easy. One thing that really annoyed me recently was that magnet links would default to Transmission instead of Vuze. I’ve since decided that I actually prefer Transmission now that it has DHT, but here’s how to adjust the association:
At the terminal run:
This will open up the gnome configuration editor. The magnet url handler can be found at: /desktop/gnome/url-handlers/magnet.
Then set the ‘command’ string to launch the application you want. For example, the transmission command line would be:
The %s simply appends the link after launching transmission. You can change transmission to azureus if you want Vuze to run instead, or any bittorrent client of your choice.
