Recently Ubuntu 12.04 have started not to remember my keyboard options - as image http://img.ivanovs.info/XKnu0A.png
I always use Caps Lock to change my layout, and it used to work fine before. But now when I log in, changing it with Caps Lock doesn't work. I have to go to options, deselect "Caps Lock", select it again, and then it starts to work.
What may cause this problem? Thanks in advance.
