nvidia-settings runs.

/etc/X11/xorg.conf 73 lines, starting with:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 390.87  (root at ENU-2)  Sun Jan 6 15:29:25 PST 
2019

It also has a set of lines:

Section "Device"
     Identifier     "Device0"
     Driver         "nvidia"
     VendorName     "NVIDIA Corporation"
     BoardName      "GeForce GT 610"
EndSection

(When I saved that configuration there were two screens. In this file I 
only see screen 0. Should I try running nvidia-setting again as root, 
which I did the first time) and see if the changes stick?
