the final part of my upgrade saga was installation of new nvidia drivers, 
which has in the past taken at least two days and required anguish, blood 
sacrifices to unknown demons, and angry outburts at anyone who encounters 
me.

but i just now installed the nvisia drivers for ubuntu-16.04 and they . . . 
just worked! (the act of writing my particular configuration, primaty 
monitor below secondary monitor, won't write to the x.org configuration 
file, so i have to redo it on every reboot, but that's as it has always 
been.)

now if i could cook up the mouse cursor i've wanted ever since i switched 
from OS/2 to linux. there was an OS/2 utility that allowed one to write 
one's own mouse (and other) cursors, and i got it and used it and loved it 
because it was possible to make a pointer arrow that was the reverse of 
whatever it was over -- black on white, white on black, blue on red, etc., 
to the point of even being half one color and half the other when it 
rested on an edge. this made it manifestly visible, always. linux has 
nothing to match it and i intend to undertake a course of study that will 
result in its being replicated for linux.

i'll send postcards.
