cool, thanks for that. I guess it is just a matter of patience until
it tickles down to Linux Mint.

as far as I can tell, I think that's what was happening.

the Jack error is unrelated and is still there. It doesn't seem to do
any harm though as it is running fine.

I agree entirely. It did cost me some time to figure out what is
happening, and that's frustrating. But if you'd ask me what could be
done to make it better or foolprof - I don't think there is a flaw in
