That "usbhid.mousepoll=0" was not in that file, so I appended it, but 
will not reboot until I am at the machine to observe.  Thank you very 
much.

I also see that apt is upgrading 9 packages, including the raspberry 
kernel.  So I will check when its done to see if that option survived.

And at the 54% mark of the unpack and install, it has crashed, or 
disconnected my ssh login.  No, it was installing kernel headers, which 
apparently took several minutes but is now progressing again. And that 
setting survived the update from kernel 4.4.27 v7 to 4.4.34 v7. Reboot 
in progress, uname now shows 

4.4.34-v7+ #930 SMP Wed Nov 23 15:20:41 GMT 2016 armv7l GNU/Linux

Looks promising. Mouse is fixed.

Now I wish for more workspaces. 1 more would be a great help. I am 
spoiled with 10 setup on this old relic phenom. :)

Thanks Eric.

Cheers, Gene Heskett
