A screenshot demonstrating the conflict between gdm and env.
I selected "Chinese (China)" at the login screen to run a Chinese language session of Ubuntu. In this Chinese Ubuntu session I am trying to run an English instance of Firefox by prepending "env LANG=en_US.UTF-8". Note how Firefox comes up in Chinese instead of English.
