For those who got here because you're losing one or more keyboard layouts, see bug #363169 (https://bugs.launchpad.net/ubuntu/+source/libxklavier/+bug/363169). The following fixed the keyboard layout problem for me on 9.04:
1) Read about updating from PPAs here: https://help.launchpad.net/Packaging/PPA#Installing%20software%20from%20a%20PPA
2) Add Sergey's PPA to your apt sources: https://launchpad.net/~sergey-udaltsov/+archive/ppa
3) Update your software, making sure that one of the packages updated is "libxklavier - 3.9-0ubuntu3"
4) Restart your computer
