Last year I installed on my wife's laptop a 2013 version of lubuntu.
Under configuration first language was Spanish and then English.
I added a top bar with some icons, one of them was the used language.
It always displayed "US" despite the real lang was "ES" or "SP" (I don't know if this icon should be used to change the language like other OS, no option but set a country flag, font size...)
She recently upgrade to 14.04 and the keyword worked sometimes. I fixed that changing kb input method from iBus to None.
At this time she is able to write Spanish chars like á ó and ñ BUT in Chromium Gmail.
Strangely the ñ or Ñ work fine but the accent key seems not, no way to write accented vowels.
Gmail has a menu with some Spanish options aside the configuration wheel.
I tried changing to other options but it is the same thing.
Thanks for any help
