F18 keyboard layout change

[Parag Nemade]

Hi,
    Please be informed that there is now a default limited keyboard 
layouts available per language.  You can check which layouts are default 
loaded by gnome[1]. If you want any change then report bug in upstream 
bugzilla.
    Also, note that upstream has given option to enable all the 
installed keymap by using following command
  "gsettings set org.gnome.desktop.input-sources show-all-sources true"

Thanks,
Parag.
