I have an nVidia card in the computer in the living room with its HDMI
port connected to the TV. When I boot up the machine the primary screen
is the TV. But with the underscan issue (described some years ago), it
is hard to click on the controls at the top of the screen. I've tried
changing the default screen with nvidia-settings, but the changes never
take. This morning I remembered that I'm supposed to run
nvidia-settings with sudo. The OS is xubuntu 18.04. I get this message
when I run nvidia-settings:
--------------------------------
rsteff@ENU-1:~/Desktop$ sudo nvidia-settings
[sudo] password for rsteff:

application profiles will continue to work, but values cannot be
prepopulated or validated, and will not be listed in the help text.
Please see the README for possible values and descriptions.

Package xorg-server was not found in the pkg-config search path.
Perhaps you should add the directory containing `xorg-server.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xorg-server' found
--------------------------------
I tried searching for the first couple of errors the responses might
just as well have been in Greek.
One of the hits I got later on recommended running nvidia-settings using
gksudo. This, I learned, has been deprecated, and neither of the
recommended alternatives worked. One was to us admin:// nvidia-settings.
That returned admin://: no such file or directory. The other was to use
pkexec nvidia-settings. That returned "Unable to init server: Coundd not
connect: Connection refuse. Error: The control display is undefined;
please run '/usr/bin/nvidia-settings --help' for usage information."
A clue stick would be appreciated.
