How to properly HiDPI Linux in 2018

I have a X1 Carbon from Lenovo with an UHD Dolby Vision Display. Yes, this beauty is on par with an Apple LG 5K screen or an MBP Retina Display of the latest iteration.

After you removed the horrendous Malware called Microsoft Windows pre-installed on the Notebook and booted in your favorite Linux distro and Desktop Environment you will be faced with a ton of forum and blog articles and wikis on how to propery scale any GTK3/Gnome3 based DE.

Multiples of your native resolution is not a problem, but it's considerably too large by any standard. 200%, 300%, etc.

Enter Fractional Scaling

Weyland Fail

They promote Weyland, the successor of Xorg/X11. So I tried Weyland and it sucks currently with HiDPI, since it scales up from the lower multiple of 100%, e.g. if you want 175% scaling, it scales up from 100% resulting in unsharp and blurry text - doing your beloved 4K/5K screens no justice at all.

X11 Win

It's possible in X11 with a Bash one-liner. You will find it easily via DuckDuckGo or any other secure and free search engine.

XFCE Mega-Win

XFCE scales out of the box. Just a few simple tweaks in its extensive Window Manager settings are needed. HowTo - it's all in the Manjaro and Arch Linux Wiki. Well Documented, easy to follow, ready to rock.

Once again, Linux wins on whatever resolution or hardware you throw it. It is an operating system second to none. Period.
