If you're a fan of Ubuntu and KDE, then KDE Neon is arguably the best option we have today. It provides the latest, cutting-edge version of KDE alongside the latest LTS edition of Ubuntu.
One slight downside (or upside, depending on your point of view) is that it's a rather minimal installation, and some of basics like Libre Office are absent by default.
One of the first things is to install drivers - in my case, I get better resolution options and the correct refresh rate selected.
Find out what driveres are available by entering the command:
sudo ubuntu-drivers devices
This will output something like:
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 == model : GF108GLM [NVS 5200M] modalias : pci:v000010DEd00000DFCsv00001028sd00001534bc03sc00i00 vendor : NVIDIA Corporation driver : nvidia-304 - distro non-free driver : nvidia-340 - distro non-free == /sys/devices/pci0000:00/0000:00:1c.1/0000:03:00.0 == model : BCM4313 802.11bgn Wireless Network Adapter modalias : pci:v000014E4d00004727sv00001028sd00000015bc02sc80i00 vendor : Broadcom Corporation driver : bcmwl-kernel-source - distro non-free == cpu-microcode.py == driver : intel-microcode - distro non-free
From the list, simply do a
sudo apt-get install on the drivers you'd like to install. In my case, I entered the following:
sudo apt-get install nvidia-367 bcmwl-kernel-source intel-microcode
