Okay, let's get X workingg on my new Stretch

[Bob Bernstein <poobah@ruptured-duck.com>]

The mouse proves elusive:

# dmesg |grep -i mouse
[    2.645218] mousedev: PS/2 mouse device common for all mice
[    3.225344] psmouse serio1: logips2pp: Detected unknown 
Logitech mouse model
90
[    3.722367] input: ImExPS/2 Logitech Explorer Mouse as 
/devices/platform/i8042/serio1/input/input2

BUT:

Running $ X -configure yields:

"Xorg is not able to detect your mouse.
"Edit the file and correct the Device."

The file in question looks like this:

Running X -config xorg.conf.new produces a nice blank black 
screen but no sign of a mouse.

Thank you
