Just reciprocating the "+1" that ivaylo sent me a few messages earlier in
this thread. :-)
I would add that it is funny to defend productivity and rant against
bloatware while, at the same time, trying to install a proprietary driver
whose only purpose (versus what Trisquel ships by default) is to enable 3D
acceleration!
By the way, we have not pointed out that an experimental support of this
rendering acceleration is available via the package
libgl1-mesa-dri-experimental which is in Trisquel's repositories.
Nevertheless, these features come at the cost of less stability (hence the
"experimental" in the name).
