Hi Dave,
I'm not sure I subscribe to this explanation. I had Lucid Lynx running on
this very same laptop and panel, and that was working without a hitch. To be
honest, I ran Kubuntu on that at the time, but technically this all seems to
work, it's just that Ubuntu doesn't take advantage. I will re-test this
using Kubuntu, to see if it works there.
