virtualbox.org

Hey guys, I have a fresh installation of Gentoo Linux. I've used the example xorg.conf file from the Guest Additions. Using the latest everything. Virtualbox 3.2.4 + 3.2.4 Guest Additions of course...

As root, run the following:

Odd, I don't have that group on my Ubuntu VMs. Nor do I need to be in any group for 3D capabilities inside the Guest.
