You need to first install Trisquel on your drive to then install and enjoy
{linux-generic,xserver-xorg,libgl1-mesa-glx}-lts-saucy (by the way, you write
"this is the only real suggestion that I could try while everyone else wants
to give pep talks" even if I proposed, and you ignored, the same advice in
the second reply of this thread).
Indeed, a reboot is needed between the "install" part and the "enjoy" one.
Getting the latest kernel (rather than "linux-generic-lts-saucy"), as you
did, may help as well.
