Hi everyone!

Ubuntu 15.10 is out, it’s time for a quick overview and new  guide!

Ubuntu 15.10 brings a lot of changes. The most important is probably the usage of kernel 4.
On the Dell XPS 13 9343, some bugs have been fixed and some new bugs have appear. As usual, I will bring together all the information I have gathered to fix the remaining issue and make the Dell XPS 13 the most enjoyable Ubuntu experience possible.

I will describe how to do a fresh Ubuntu 15.10 installation. I have not tested the upgrade (15.04 -> 15.10), but I see no reason to meet problems doing so. If you have done it, please leave a feedback ! 🙂

In other news, after reading all the great feedback (open source drivers, better ranges, etc…) I have ordered an Intel 7265 wireless card . As soon as I got it installed, I will review it and write a small guide on how to install it. Stay tuned!
