I've been using dual screens on Linux since 2009 and for the last 2 years triple screens.

My current PC is using and nVidia 1660 GPU to drive this.

I'm running Ubuntu 20.04. It wasn't out-of-the-box easy to install, but running installer in safe-mode worked and regular boots are as normal.

Even on laptops dual screens work provided the laptop supports it.
