Few hours ago WX notation phonetic keyboard layout for Devnagari(Hindi) has been included into Ubuntu. This closes the ubuntu #274024 and freedesktop-bugs #19753 reported last year. This is a great news for the Wx keyboard users, they can now have this keyboard layout by default in gnu/Linux.
While at University of Hyderabad I had copy the symbols file for the keyboard layout every time a new gnu/Linux system was installed. Its wonderful to see a solution developed for use inside our lab has been contributed back to the gnu/Linux community worldwide.
