Today I got a new laptop xps 15 9560. After A LOT of pain I was ablet to finally install Ubuntu 16.04 on the bloody thing. Took me about 3 hours, had to mess within Bios. Reading this thread helped me quite a bit http://en.community.dell.com/support-forums/laptop/f/3518/t/20004529.

To make a long story short when I finally got the usb to boot, I did not create a second partition, but just installed Ubuntu.

Now nothing on my thunderbolt dock (TB16) works. After reading a bit on the arch wiki https://wiki.archlinux.org/index.php/Dell_XPS_15_(9550). I seem to have to disable some security features to enable the full functionality of the dock. Linking to this article to this article. http://www.dell.com/support/article/ed/en/edbsdt1/sln171755/updating-the-dell-bios-in-linux-and-ubuntu-environments?lang=en However after some light reading this seems quite advanced, and is just to update the bios not change it.

A similar thread on the wiki https://wiki.archlinux.org/index.php/Dell_XPS_13_(9360) proposes another method for updating the bios.

I know it was stupid to get rid of windows, but after such a long winded process of finally being able to boot, I did not want to go though a similar process getting dual-boot up and running.

Any help getting the dock up and running when I no longer have access to windows would be wonderful.
