Because I'm paranoid, I update my virtualbox ~amd64-gentoo-guest machine every day *before* I update my (real hardware) "production" machine. (The definition of "production" is left as an exercise for the reader.)
Not long ago I noticed that the vbox guest machine failed to start a gnome session because "3D hardware support" is not available on the guest machine. To make a very long story short, I downgraded the xorg-server on the gentoo guest from 1.16.0 to 1.15.1, and now gnome3 is happy again. Techie detail for nerds only: /usr/libexec/gnome-session-check-accelerated returns an error message with xorg-server-1.16.0, but works normally with xorg-server-1.15.1. Has anyone else seen the same behavior? Thx
