Thank you for the reply.  :-)

Choose 'No'.


And a new issue:

Xfce -> Settings -> Display -> Resolution now only offers three choices:

1024x768
800x600
640x480


The laptop has a 1920x1080 screen.  The external monitor is 1920x1080. 
The nouveau driver was able to drive both the laptop display and the 
external monitor at 1920x1080.  I would like to do so with the non-free 
Nvidia legacy driver.


Looking around for X configuration files:

2021-01-04 19:34:58 root@dipsy ~
# locate xorg.conf
/usr/share/X11/xorg.conf.d
/usr/share/X11/xorg.conf.d/10-amdgpu.conf
/usr/share/X11/xorg.conf.d/10-quirks.conf
/usr/share/X11/xorg.conf.d/10-radeon.conf
/usr/share/X11/xorg.conf.d/40-libinput.conf
/usr/share/X11/xorg.conf.d/70-wacom.conf
/usr/share/X11/xorg.conf.d/nvidia-drm-outputclass.conf
/usr/share/doc/xserver-xorg-video-intel/xorg.conf
/usr/share/man/man5/xorg.conf.5.gz
/usr/share/man/man5/xorg.conf.d.5.gz


RTFM xorg.conf(5), I am unsure if any of the located files (above) are 
active:

        Xorg uses a configuration file called xorg.conf and files ending 
in the
        suffix .conf from the directory xorg.conf.d for its initial 
setup.  The
        xorg.conf configuration file is searched for in  the  following 
places
        when the server is started as a normal user:

            /etc/X11/<cmdline>
            /usr/etc/X11/<cmdline>
            /etc/X11/$XORGCONFIG
            /usr/etc/X11/$XORGCONFIG
            /etc/X11/xorg.conf
            /etc/xorg.conf
            /usr/etc/X11/xorg.conf.<hostname>
            /usr/etc/X11/xorg.conf
            /usr/lib/X11/xorg.conf.<hostname>
            /usr/lib/X11/xorg.conf


Any suggestions for getting the laptop display and external monitor 
working at 1920x1080?
