When I purchased my Dell XPS 13 6360 pre-installed with Ubuntu 16.04, there were a few things I needed to setup prior to using it.
Dell says that it is unable to ship OEM Ubuntu systems with the "super" key enabled on non-Windows operating systems. I'm sure that has something to do with Dell's Licensing agreement with Microsoft since the key has the Windows logo on it. Dell provides a tutorial in their Knowledge Base on how to do this. http://www.dell.com/support/article/us/en/19/how12108/how-to-enable-the-ubuntu-super-key-on-dell-oem-ubuntu-installations. There three easy steps, all done in a terminal, followed by a reboot.
If you are wanting to use the installed version of the operating system provided by Dell, you can skip this step. When I purchased my XPS13, the version of Ubuntu installed was 16.04 LTS. That release is over two years old and a new LTS (long term support) version is available. I prefer the Ubuntu MATE flavor, so rather than simply upgrade to Ubuntu 18.04, I chose to replace the installed Ubuntu with Ubuntu MATE 18.04 LTS. The installation went smoothly, just as I expected, and I've updated to later releases since then.
Most laptop computers these days use a touch-enabled device in place of an external mouse. Given that the built-in "disable touchpad while typing" feature did not work for me, having the ability to manually disable the touch-enabled device can prevent typing mistakes. With Windows installed, Dell provide the function key F7 that alternately enables and disables the device. I have documented how to create a script that enables this functionality when using Linux. See the article "Toggle Your Laptop's Trackpad/Touchpad On and Off".
