Allows you to use i3 in a GNOME-Flashback session. Large parts of this are based on the existing i3-gnome project.
This has been tested working on GNOME version 3.34.
For Arch users see the AUR package for a more easy intallation.
For Ubuntu (19.10), ensure prerequisites are installed:
sudo apt install i3 gnome-flashback build-essential
Then install i3-gnome-flashback:
sudo make install
And to prevent Nautilus from taking over the screen upon login, run this:
gsettings set org.gnome.desktop.background show-desktop-icons false
For other distributions, clone this repository and run make install with root priviledges.
To understand how the files in this repo work to initialize an i3 and GNOME session, refer to this GNOME wiki on session management.
