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:

I can't give you details, but a couple of things might help.
First, Ubuntu recently came out with updated versions of some of their
nVidia drivers. They were in the update manager for 18.04 and, with
great trepidation, I installed them when they first appeared.
Thankfully, they worked.
Second, you might try switching to root instead of using sudo. I don't
fully understand why, but apparently there are some differences. To
become root you do 'sudo su.' One thing that I learned a long time ago
is that 'su' means 'switch user,' not 'super user.'
I always thought su was just short for sudo. When it comes to Linux, I
often learn something new every time I try to "fix" something. I'll try
that before trying to change to Ubuntu's version of nVidia drivers.
Thanks.
