Are the versions of the kernels on your Trisquel and your Ubuntu systems the
same? One way to know the version is to open a terminal and execute:
$ uname -r
You could try to update Trisquel's kernel:
https://trisquel.info/en/wiki/update-linux-libre-kernel
And you could contact Chris (ThinkPenguin's CEO and user of Trisquel):
https://trisquel.info/users/chris/contact or, probably better,
https://www.thinkpenguin.com/contact
ThinkPenguin has this documentation too:
