The keyboard layout GUI in 12.04 system settings is not responding on my laptop. In a different post a workaround was found (see: Cannot switch keyboard layouts).
Problem now: Having manually altered the file /etc/default/keyboard I can now access all the keyboard layouts I want except for one: Russian phonetic. (i.e. the letters are placed where the equivalent Latin letters are - qwerty) This keyboard was in the old Gnome and it is still listed in the "system settings" keyboard GUI. But the GUI is not responding.
I can toggle between the official Russian keyboard and Norwegian with the command:
sudo setxkbmap -option grp:alt_shift_toggle no,ru
But "ru phonetic" is not understood. What is the code for the phonetic Russian keyboard?
