I've managed to create a custom keyboard layout for my language.
Now that the keyboard is in a state that I can share it. I don't know how to make it a redistributable package.
To add it to the official
xkeyboard-config package, you would develop it as a patch for the
xkeyboard-config package. See their code contribution guide; contributed layouts are made by patches on their bug tracker. You can clone the upstream repository with:
git clone git://anongit.freedesktop.org/git/xkeyboard-config
From a quick glance at your layout, I think you need to add the
default keyword to the stanza definition (
default xkb_symbols "basic"), to declare that layout the default for that file. Your file itself would be put in the
In addition to your new layout file, you'll need to add it to the rules templates (
rules/base.xml.in or possibly
rules/base.extras.xml.in -- the
rules/evdev.xml file will be generated from the same template).
Doublecheck the project documentation for other specifics that I might have missed.
You could also add that patch to the Ubuntu source package apply it with the standard dpkg build tools. This would allow you to distribute your modifications to other Ubuntu users with minimal difficulty. See questions like How to create and maintain patch on Debian package? for more specifics.
