Got a new machine (see signature) a few weeks ago. Tested many distros:
1. Ubuntu (17.10 and 18.04): no Fn buttons, not possible to adjust display brightness.
2. Kubuntu 18.04 (beta at that time): failed to install
2. Opensuse, same as Ubuntu
3. Antergos, failed to install
MX17: everything and I mean everything working out of the box. Immediately. No hassles, no tweaks. Nothing. Just perfectly awesome. I had just to adjust a few things due to my general inexperience.
And also, great community here: kind and supportive.
