I got this reply from DisplayLink: "[The issue] is a problem in the Ubuntu X server update. We have an article on this problem, including possible work arounds, and an explanation of the technical problem in X server here: support.displaylink.com/.../1181623-displaylink-ubuntu-driver-after-recent-x-upgrades "
Hi Barton, Justin, Jared, et al, can you please talk to Displaylink to get them to fix the current issues with the D3100 docking station? I know Dell has outsourced the driver for their product to Displaylink. So far they've done a good job...but since end of April (!!!!) it's no longer working with the current driver (February 2017). A  lot of customers are complaining on the displaylink forum, just like I do:but apparently Displaylink doesn't care. They could at least respond that they're working on it.I'd love to open a case with them, but I haven't found a way yet.... could you *please* tell me how I could open a case with Displaylink so that it's officially recorded that their driver isn't working anymore. I hope I didn't shell out 150 Euros for a broken Docking station....would be a shame!![URL]#post83621
