I'm having a problem with the language display on my Ubuntu interface, the version I'm using is Ubuntu 12.04 (I can't upgrade it due to low capacities of my pc) I had English as a default language from the beginning, then I installed Spanish much later on, I installed it under "System Settings > Language support" then I installed it for input method using ibus, my purpose was to install Spanish for input method not to change the interface language, everything was fine, I could use the input Spanish or switch to English whenever I wanted, however after a month something happened...
The problem is this: I had to restart my computer and then when I logged in the interface was in Spanish ??? even a windows message appeared to change names of locations of folders in Spanish... I never selected Spanish as a main language under "Language support", so I uninstalled Spanish language and then made sure to have English only, I rebooted the system many times and now the interface is in both languages... part of the menu of the interface is in English and Spanish, all mixed... very strange.
I was trying to get a screenshot from the menu but it seems this option doesn't work when the menu is displayed.
So what I'm asking is... How can I have only English displayed as it used to be?
By the way, I'm a beginner user in Ubuntu, I hope you guys could help me.
Thank you for reading.
