I installed open suse 11 with kde4 with my locale (Greek) settings.
How can I change system (kde) lang (menu, help, descriptions etc.) and set it to English?

Going to kde control center and pressing the "add lang" button, results only the Greek one.
Going to "change default locale" doesn't seems to do something.
I tried changing the default locale (I tried English and US ones) from Greek.
kde informed me that the locale changed and needs to logoff-on.
I tried it (as well as restarting my sytem), but although the English locale is indicating as active, everything is still in Greek lang.

Any hints available?
