Err, I meant "renamed", not "disabled", sorry. The advice for fixing it still stands though. :) Since this change in the default driver selection for Xorg is something that many people might not expect, I've also reported a bug against Debian's release notes so that when Stretch is released people don't face the same surprise you did: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=860259 Regards, Christian
