I use Ubuntu-Gnome 13.04 and I can't change system language.
I set it to Polish with "language & regions".
It was though because there is no option for adding so i installed:
language-pack-pl
language-pack-gnome-pl
then i could pick it in "language & regions" and then reboot.
However this didn't solve my problem
I also change it with gnome-language-selector and still got english.
Please help, because if the language is other than polish i will have to switch back to windows.
I like the gnome3.

Obviously the language support tools are still incomplete in Ubuntu GNOME. Desktop Help states the following:
Only after selecting a language there clicking on Done has no effect.
To have the language selection back in the form it is installed in other releases we have to install language-selector-gnome . After we did so, we will have an additional icon "Language Support" in our System Settings from where we can install any supported language by choosing "Install/Remove Languages":
Drag the interesting language to the top of the list. Select "Apply System Wide" to also have this language at log in, and system wide.
