I am trying to change the keyboard layout for ubuntu 13.10 ltsp clients.

I edited /var/lib/tftpboot/ltsp/i386/lts.conf (which was empty after the install).

What works is de/german, but this is the keyboard setting that the system was installed with:

```
[default]
XKBLAYOUT=de

```

I can also change the file to

```
[default]
XKBLAYOUT=us

```

This changes all clients to an us-keyboard. But how can different clients/users use different layouts or even switch during a session?
