I have a Lenovo laptop with a NVidia graphic card and an external monitor, and I'm struggling to configure it so that the monitor extends the laptop screen on the left.

Output of xrandr -q: https://pastebin.com/wXsLCKeD The external monitor corresponds to the output DP-0, and the laptop screen to LVDS-1-1.

I've tried the following:

xrandr \
  --output DP-0 --mode 1920x1080 --left-of LVDS-1-1 \
  --output LVDS-1-1 --mode 1920x1080

xrandr \
  --output DP-0 --auto --left-of LVDS-1-1 \
  --output LVDS-1-1 --mode auto      

xrandr \
  --output LVDS-1-1 --auto --right-of DP-0 \
  --output DP-0 --auto

But all these screw up the resolution completely (photo of the main screen, photo of the laptop screen).

The only thing I've managed to get working is to have the same output on both screens:

xrandr --output DP-0 --same-as LVDS-1-1

My graphic drivers are up to date. Here's the output of lspci if that's of any help.
