I also noticed that the wiki has some points on this: https://wiki.debian.org/NewInStretch """ Upgrade issues * For many Intel graphics chipsets, the Stretch X server will use the modeset driver instead of the intel driver. The modeset driver may require non-free firmware (firmware-misc-nonfree) to activate features, even on systems which did not use this firmware under Jessie. * For some older graphics chipsets, support has been relegated to "legacy drivers", which require the old setuid X server to run. Install xserver-xorg-legacy if you require one of these drivers. """ I believe the release-notes has the latter point, but not the former. I will add that now. Thanks, ~Niels
