I've created a custom keymap based on Bepo (a french dvorak-like), which is working correctly when I set it using
setxkbmap fr bepo_prog
However, this keyboard mapping is not visible in Gnome input sources selector. It wouldn't be a problem if I used my bepo keyboard everytime, but it is a laptop so sometimes I go back to azerty. It is especially problematic when I want to unlock the computer, since the keymap set by setxkbmap takes priority over Gnome shell layout selector (i.e. layout selector does not work anymore), and it can be extremely painful to put the password (which is really long) to unlock the session (I just started learning bepo so it can be hard to type for now without looking at the keyboard).
Is there anyway for Gnome to see this custom layout?
I'm on a Fedora 21, with Gnome 3.14.
Thanks in advance!
