Firefox on Xbian

README.md

Firefox on Xbian

These scripts allow you to launch Firefox on XBian.

Usage

When you are in Kodi and you want to switch to Firefox, you just have to quit (no shutdown, just quit). Firefox will then start automatically. Now when you want to get back to Kodi, just quit Firefox and Kodi will start back automatically.

How it works?

The script will run in the background and check for the kodi.bin process.

  1. If the kodi.bin process does not exist, it will start Firefox with a minimal X environment
  2. When you close Firefox, it will start Kodi back
  3. Back to 1.

Installation

As root, install git, clone this gist, and run the firefox_on_xbian.sh script:

apt install git
git clone https://gist.github.com/4b92d9b48ef203b6fcfcfeb2f7e95a6d.git firefox_on_debian
cd firefox_on_debian
chmod +x firefox_on_debian.sh

Can't get it to work either. Exiting Kodi leads to a shell login. When I try to run matchbox-window-manager manually, it complains that no display is found (also in the Xorg log file). Any ideas?

exit from kodi; enter 'xbian' and 'raspberry' as root login/pass; see a blue screen with list of settings; click 'esc' on your keyboard. You'll see the command line on the bottom of the screen.
