Comment 3 for bug 1026510

0. Relocate to Spain [optional]

1. Install lubuntu with choosing Spanish layout during installation.

2. Spend 1 week trying to buy US keyboard in Spain [or buy online]

3. Replace your ES keyboard with US one.

4. Run your Ubuntu

5. Run lxkeymap and change layout

6. Reboot computer

7. GOTO 5

I made some workaround changing keyboard layout on the kernel level or messing in etc - so its changed global now. Unfortunately I don't remember what exactly - but for now I am happy not to have using lxkeymap again.

I hope it help - if you have more questions - let me know.
