Hi everyone, hi lembas.
I complety forgot that I posted there, and got used to Ubuntu for working
purpose. Still, I'd like to use Trisquel instead of the fraud that Ubuntu and
its Amazon ad appears to be.
So I retrieved the info you asked for, lembas (cf. screenshots). Few more
elements : the icon on the rigth corner remains "unconnected" even if I
manually configure a connection.
About kernel : how to update it on another OS while running Ubuntu ? I
couldn't the answer on the link you gave me.
Thanks a lot for helping me (despite my terrible english)
