[Hampshire] Conky

I've recently started using this nifty piece of software. However I
cannot get Ubuntu to run it at logon. Most of the advice I've seen on
the internet says to run it from a script after sleeping for a while.
However even this doesn't work for me. I also can't find any references
to conky in the log files. Can anyone suggest a way for me to debug
this, or an alternative way of running it at logon?

Thanks,
Leo
