What driver to use for AOC e2251fw

[ctoth]

So I got it working with udl, and it does work along with the proprietary nvidia drivers, but I have a side effect. I'm on Ubuntu Studio 16.04 which uses Xfce 4.12, I'm not sure how much that contributes.
I followed the https://wiki.archlinux.org/index.php/DisplayLink:

modprobe udl
xrandr --setprovideroutputsource 1 0

Essentially instead of two separate monitors, now I have one giant wide monitor. If I maximize a window, it spans out to both monitors. And there's an additional very annoying scrolling effect on the primary monitor: when I travel with my mouse to the secondary, the primary content starts scrolling proportionally where my cursor is. When my cursor is far right, I see the same thing on both monitors. In order to get back the intended view on the primary screen, I need to go all the way to the far left to get the scroll back to the left. This almost defeats the purpose of the two monitors. How can I overcome that? Should I switch window manager? Or is there some configuration option?
