I am a beginner and I am using Ubuntu 14.04 LTS with text entry given by English International with dead keys.
Everything works well but instead of getting "ç" I get "ć".
Yes, the key that I have in my keyboard is apostrophe and not accent.
I have found some solutions in How to type cedilha, but they assume that you are able to find a file /usr/lib/gtk-2.0/2.10.0/gtk.immodules, but I am not able to do that.
Can someone help me?
