An install with the apt-get method left XFCE with no screensaver and no screensaver module in the settings. That was a problem because somebody thought there was and tried to turn it on. The screen went black and I had to reboot the machine to get video back. Installing xscreensaver seems to have fixed that.
Stretch is a mixed blessing and is going to take some getting used to -- lots of things don't work anymore. But some have improved. SSH has gone completely odd. The Wifi dongle is now called wlxe84e0629c8e0. My iptables script doesn't work anymore. Etc. -- Glenn English
