Difficult this. It doesn't look hardware related because X comes up and you get what is known as the "fail whale" (and a most informative and helpful message :) ). Also difficult because what you had personally configured on Wheezy is unknown. So we'll try a thing or two. No guarantees. Disable logging in with gdm3 with systemctl set-default multi-user.target You can reverse this with systemctl set-default graphical.target Make sure you have xinit installed ('dpkg -l xinit') and reboot. Log in and run 'startx'. Over to you. -- Brian.
