It's an old IBM T41. In Windows both Alt keys act the same. It's only in KDE and GNOME that I've noticed the difference. There's nothing obvious in the information I've been able to find that indicates it's using an international keyboard layout. More details in [link|http://z.iwethey.org/forums/render/content/show?contentid=296154|#296154].

You're exactly right about [link|http://kubuntu.org/|Kubuntu] - it's Ubuntu with KDE as the default desktop. I'm tempted to try out [link|http://xubuntu.org/|Xubuntu] one of these days (Ubuntu with the Xfce desktop as the default). Maybe it uses keyboard shortcuts that are more to my liking...

Thanks.

Cheers,
Scott.
