In a thread of GRUB issues, we drifted into some general feedback on 7:

onpon4 wrote about the lack of easy access to Compiz in 7:
"The tool you're talking about was from the Trisquel devs, and it was dropped
in Trisquel 7. You now need to enable Compiz by yourself. The script is
pretty simple, though, so you could copy it from Trisquel 6 to Trisquel 7, or
8 (whatever you upgrade to next), or just read it to understand how to enable
Compiz manually."
Ok. So does the script you speak of download Compiz from the repositories
before it does anything else? Or is it that Compiz is still in the default
install, but there's no longer a GUI way to turn it on?
