Yes, this is what Onpon told me, as quoted in the comment you're replying to.
What I need to know to get Compiz working again in Trisquel 7 is:* what is this special Trisquel/Compiz script called, and where do I install it from or copy it from (online? copy from my 6 install?)
* do I install Compiz from the repos first, then the script? OR, install the script first, then Compiz?OR, is installing Compiz one of jobs done automatically when I runing the script?
