Arrow What driver to use for AOC e2251fw

A year ago I tried to get my monitor working with Linux when the Linux driver was new, and now my primary operating system will be Ubuntu Studio. I'm on 16.04 at this moment. Reading through forums I realized that I may not even need the evdi driver?

In some topics someone from DisplayLink told that if the device is DL-1xx, then the `udl` driver should be used. AOC e2251fw is somewhat old, only USB 2.0, and AFAIK it uses DL-165 (by this service manual (https://www.manualslib.com/manual/10...page=10#manual - V/A processor: DL-165 U401).

I would like a confirmation about that. My laptop's HDMI didn't work with the nouveau driver, so I'm currently using the proprietary one. I wonder in case I should use the `udl` driver (which I suspect yes https://wiki.archlinux.org/index.php/DisplayLink), can I keep the proprietary nvidia driver? (I suspect no). I may try to disable the nvidia from the BIOS and go with the Intel HD, people seem to have more success with that.

Please share your advice and thoughts with me.

Question udl works

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:
Quote:
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?
