Unfortunately there is some kind of issue iwth linux support for displaylink chips that this uses, there is no roadmap to linux support for them as far as I know, if you google for linux and usb3 displaylink you'll find a few forum discussions on this topic,, i've just stopped myself buying one on the basis of the news from the internet, you'll unfortunately be limited to a single displayport connection from your xps13 for now.  there was an ultrasharp mnitor with this hub more or less built in i saw a little while ago, and similarly no support.
Hello! I recently purchased the new XPS13 (2015 model) and a D3100 Docking station. The main reason for choosing a Dell laptop is because of project sputnik and their fantastic linux support. However, the docking station does not work with Ubuntu 14.10 (or any other distros I've tried). The USB, Ethernet, Sound etc. works fine, the displays does not however, none of the ports. This is quite bad as I paid a lot of money for this docking station just because it had multiple monitor support. Dell does not state anywhere on their webpage that the display does not work with this docking station when running Linux. Does anyone know if dell is working on this issue or is it DisplayLink which is solely responsible to fix this? Cheers
