Oi! Thank you!Mine is Positivo Stilo DS3558. But I'll try to see if I can somehow follow your instructions!
I'll check Mampir's solution, thank your for your help.About the screen reader, it is quite important to take care of accessibility in order to include people with functional diversity. I succeeded to deactivate it after installation on Trisquel 7 but not on Trisquel 8 (maybe because it may be not quite ready yet).
See you!
