Using only external monitor

[rmcellig]

I have an external monitor attached to my laptop. I only want to be able to use that screen and not have anything show up on my laptop screen when the monitor is plugged in. Is this possible? Do I have to go into the Nvidia settings somewhere to make the changes if this is possible?

Yes, it's possible. Use xrandr for this. Example:

$ xrandr --output LVDS1 --off

Here LVDS1 it's a name of built-in screen of your laptop.

I tried that but this is what I got:

randy@mom-laptop:~$ xrandr --output LVDS1 --off
xrandr: Failed to get size of gamma for output default
warning: output LVDS1 not found; ignoring
randy@mom-laptop:~$

Read this:

$ man xrandr
