Is it possible to use Raspbian's new alpha OpenGL driver in Ubuntu (Mate) for the Pi2 ?
I mean the Ubuntu version offered on the Foundation's download page under "Third party images". It uses Raspbian's Pi2 kernel plus certain Raspbian drivers and raspi-config, and Ubuntu's ARMv7 repository for the application packages.
A "sudo rpi-update" on Ubuntu yesterday installed a new 4.1.7 kernel from the foundation server and later on another 4.1.7 version. ("rpi-update" is the official way in Pi2 Ubuntu to get kernel updates.)
However when I use raspi-config it doesn't show the OpenGL alpha driver as option in "Advanced".
