Comment 2 for bug 1250745

Although virtualgl isn't yet packaged for Debian/Ubuntu (it's on my todo list), virtualgl works as a drop-in replacement for primus. I've kept the recommendation in case users pick up virtualgl from a 3rd party source (i.e. the Bumblebee PPA), and because it's still recommended as the default bridge by upstream.

Also, if anything needs to be fixed in bumblebee/bbswitch/primus, I would really appreciate it if patches were forwarded to me upstream in Debian instead; there's no need to introduce unnecessary diffs...
