Adding, Editing enabled language layouts
If you want to enable additional OSK language layouts, open the Terminal Activity and edit the below file with your favourite text editor:
/home/olpc/.config/maliit.org/server.conf
The below is an example enabling the majority of available languages, with the currently active language as en_us. Note that the last line is a long single line:
