Hi,

I want to report a set-up that's working for me:

Dell XPS13
Dell D3100 docking station
Kernel 4.1.0-040100rc3
Ubuntu 15.10
i3 window manager

What is working:

2x Samsung SyncMaster E2420
Ethernet
USB, including a USB headset

What is not working:

Rotation (known issue)
Third external monitor sometimes works, usually doesn't
USB power seems on the weak side; sometimes my cell phone thinks it doesn't have enough power to charge
Audio is untested
Monitor identification / name assignment is 90% reliable, but 10% of the time the monitor IDs get shuffled; this makes auto-configuration a little flaky.

xrandr works fine; arandr works pretty well, but sometimes it takes some fidgeting with xrandr (turning things off and on again) to get everything set up. So, there's some flakeyness, but by and large it works reliably enough for day-to-day use. Enough so, I have one dock at work, one dock at home, and move between them daily. I have scripts set up to arrange displays; unfortunately, this can't be fully automated because of the lack of fully unique IDs for the monitors (UUIDs, although there may be a way to query this I haven't yet discovered).

I'm a little sad that the third external monitor doesn't work reliably, but I most miss the ability to rotate displays. Still, overall I'm happy with the set-up, so thanks DisplayLink for the Linux support.
