Comment 6 for bug 982383

I have the same problem with further ramifications. (My home directory is not encrypted.)

On installation the system defaulted to English US. I suppose this is normal. On trying to set it to English GB via the language support applet, the applet showed the change initially but did not effect the change, even after a reboot. The applet did, however, effect the change to UK regional formats in the Regional Formats tab. The applet terminated unexpectedly and set an automatic bug report.

I eventually changed the default language directly by editing /etc/default/locale. That worked. The language support applet then also showed that the language had been set to English GB. From this, I deduce that the applet is simply not rewriting the first line of /etc/default/locale.

Another user on this machine needs Brazilian Portuguese. This user's language was also now shown as the new default: English GB. This user tried to set the user-specific locale to Brazilian Portuguese. The applet did not effect the change, although, again, it did effect the change to the Brazilian regional formats.

 All appropriate language packs are installed.

Since the applet seems not to be working at the moment, please could you tell me which file I should edit to set the other user's user-specific language to Brazilian Portuguese, leaving mine as English GB? All this worked perfectly in 10.04 two years ago.

Thanks.
