I'm going to guess that this is a change in one or both of: - GPU firmware - X11 GPU driver Let's get the output from: cat /etc/debian_version to find out what you're running lspci | grep VGA to find out what your graphics hardware is dpkg --get-selections | grep firmware to find out what firmware is installed dpkg --get-selections | grep xserver-xorg-video-* to find out whether the right video driver is installed and finally, grep Driver /var/log/Xorg.0.log|grep II or if that file is missing, grep Driver ~/.local/share/xorg/Xorg.0.log | grep II to find out what driver is actually being used -dsr-
