I just got a Dell XPS 13 with Ubuntu 16.04 pre-installed, and I'm still working out all of the new-computer kinks. I'm using a Thunderbolt docking station (StarTech) to connect my peripherals. Keyboard, mouse, etc. are all fine, but the monitor is tripping me up.
I'm using a Samsung monitor (S27C230B) that only has RGB and DVI inputs, and the StarTech dock only has DisplayPort and USB-C outputs. I've got a DisplayPort-to-DVI cable, and was able to connect the monitor to my old Lenovo laptop (which has a DisplayPort plug on it, but no Thunderbolt) without any trouble. When I plug it into the dock, though, I see nothing. Neither the computer nor the monitor seems to acknowledge that there is a connection.
I tried installing the DisplayLink Ubuntu drivers (http://www.displaylink.com/downloads/ubuntu), but I can't really tell whether anything happened as a result of this. Their support site (https://support.displaylink.com/knowledgebase/articles/684649) shows the ouptput one ought to see in the terminal, and I'm missing the last two lines ("Starting DLM upstart job" and "displaylink start/running, process 3397").
If it helps, my lsusb output is:

Any ideas about how I can debug this? Would I be better off with a USB-C-to-DVI cable instead?
Thanks!
