Recommended Displaylink Adapter?
 

Is there a recommended adapter that actually works with Linux? Looking to run Ubuntu 16.04 in particular with one and would like to purchase the right one.

Which features do you want to use? I mean which external devices are you planning to connect and what is your base computer/notebook?

Display is most important. I have some older ones that are very flaky under Linux, usually hardly ever work

In my opinion, there is seldom anything that is "Plug and Play" with linux.
Most things that have a drivers will work just fine, but there is always things happening to kernel and what not, that might prevent hardware to work as intended.

I myself, have bought two HP 3005pr USB 3.0 Port Replicators. One for my office, and one back home.

I opted for this device since I have seen that others use it, and also it have the following ports:
1 x DisplayPort
1 x HDMI
1 x LAN
4 x USB 2.0
2 x USB 3.0
1 x external power input.

Can be connected via USB Type A or C (I'm using C).

I'm using the i-tec USB 3.0 docking station. Basically everything works running Ubuntu 14.04. I have got 2 external monitors, usb devices and network connected.
Sadly the DisplayLink driver causes a general high CPU usage. For more details on the high cpu issue please look at the other Linux forum threads.
