Hello, I would like to apologize for not having answered before, I didn't have time to try the suggestions until today.
I am happy to say that now I have screensaver on my zorin lite
, I only installed the following packages from Synaptic Mannager: xscreensaver; xscreensaver-data, and xscreensaver-gl ( the two firsts are related so when you marked both are selected) the last one I choose it myself since it has a cool "glmatrix" screensaver that was the one I wanted.
Thanks to swarf...for his assistance. Topic Solved.
