Fedora developer Kushal Das has written a blog post about getting Fedora 23 running on a Tegra K1 Chromebook. The particular Chromebook is the Acer CB5311. With a bit of work and following the Fedora ARM Wiki for Chromebooks, he was able to get the latest version of Fedora Workstation running on the device. He was also able to build a mainline kernel on the Tegra K1 Chromebook itself for getting the wireless support to work.
While he has graphics working (thanks to NVIDIA's Nouveau Tegra K1 contributions) and things are mostly all panning out for having a working laptop/ultrabook, the touchpad doesn't yet work. He says though the battery life is quite long and he looks forward to using it as a travel laptop. More details via Kushal Das' blog.
If you are now tempted by having a Tegra K1 ARM laptop running Fedora Linux, you can find this Acer Chromebook 13 CB5-311 for $209 USD with 2GB RAM, 16GB storage, and 13.3-inch display. There are also other models with 4GB of RAM, 32GB of storage, and full HD display.
