I have tried to set my default browser for opening URLs to Chromium using:
xdg-settings set default-web-browser chromium.desktop
(yes I checked out whether /usr/share/applications/chromium.desktop existed first before running this command and it does exist) and it returns:
xdg-settings: unknown desktop environment
i3 isn't a desktop environment so I can definitely understand this error, but is there a way around it? The reason I want xdg-open to open URLs using Chromium is that running
notebook() from the SageMath command-line attempts to open the notebook in one's default web browser (using xdg-open). Presently this obviously fails (no browser, or application for that matter, is opened to the URL), so I'd like to get this to work which I believe will require me to get xdg-open to open URLs in Chromium.
