I had the same problem after a fresh install of a 32-bit ubuntu 12.04. With the hints mentioned by the original poster the language can be restored, but in my case the language change came back multiple time which was really annoying.
I figured that apparently there is an automatically installed and non- removable entry of Chinese in the Keyboard Layout config menu in system settings. If you just open this config menu, click through all the tabs and return to the language tab, the first entry of the list will be selected, which is Chinese if you haven't installed any other language alphabetically listed before. Thus the bug seems to be connected to the Keyboard Layout config dialog which wrongly selects the first entry instead of the currently set language. Workaround: Avoid the Keyboard Layout config dialog or if you have to use it, always make sure you mark your preferred language in the list under the Language tab before closing the dialog. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/1024800 Title: Ubuntu 12.04 switches to Chinese language Status in “gnome-screensaver” package in Ubuntu: Confirmed Bug description: Again I had to fudge a report through ubuntu-bug to get this posted. Make a general bug report possible, because there are a lot of times there is no way to know what is causing the issue... On to the bug. Ubuntu 12.04 changes to Chinese, and using the language suport system in system settings gets you nowhere. It absolutely will not change it back to English. I did not want, nor did I try to change it to Chinese, it did so after a boot up. I found the solution to this problem, but that does not mean the bug is solved, and so I am posting this. The solution right now, is stated here: http://dennygoot.blogspot.com/2012/07/ubuntu-1204-changes-to-chinese-with-no.html Please help us remove this bug.
