Are you copying and pasting because sometimes that picks up stuff and won’t work. Try typing it out as i have it here.
Edit:If you are typing it maybe there is a mistake?
I guess I got it now …

Pheeew. Thx soo much. 
Must I do the lightdm stuff now as well?

I would edit the lightdm file also as it stops lightdm from loading too quickly. It’s very easy to edit and uncomment the line and change false to true and save the file.
As you can see the renderer in the line from the above command now shows your graphics card! 
Edit: It also shows nvidia is loaded and the driver version and some info about your display.
Edit2: Hopefully this helped you learn a little more.

Oh yes, even a decidedly non-geeky person can’t help but learn the one or other thing. All my friends think I’m a geek anyway. Maybe I am. Not many 54 years old housewives on Linux … and even less on Arch I guess. Can’t help it.
I had to report about my triumph over the technology in my blog:
Thx again, Rick xoxo
