OpenGL acceleration on Ubuntu 16.04

Hi all!
I am running
https://ubuntu-pi-flavour-maker.org/xenial/lubuntu-16.04-desktop-armhf-raspberry-pi.img.xz.torrent
on a pi3. It’s very stable, have built lots of software on it. Now I’d like to enable the accelerated opengl
driver. Is it present in the base config of this flavor, or do I need to install additional packages?
If there’s some better place to ask, please let me know.
Thanks!

I use lubuntu too :wink:
