I ended up doing this:
https://trisquel.info/es/forum/bring-compizs-animations-add-back-aka-compiz-plugins-extra-solved
Thank you davidnotcoulthard :)
It's been removed (since Compiz 0.9.8, I think, along with other plugins, to
accomodate for OpenGL or something like that). So the only solution is to go
back to Trisquel 6
Or maybe, just maybe, taking Compiz 0.8 from one of Debian 7's testing-period
snapshots like shown in
Also if someone has an article of why and when did this started I loved to
read it. Thank you.
