ATTENTION!
This is based on the BETA version of Fedora 25, with updates until Oct 27 2016. Things may be different with the final release
NOTE!
This is based on the x86-64 workstation version of Fedora 25 with the default GNOME desktop. Your experience with a different edition may be different.
Help needed
Not all models of this ThinkPad are equal, you may have a different WiFi adapter or display, or some options I did not have. If you tested them, please add their status down below.

Tested and Verified on Fedora 25
Information in this section has been tested and verified using Fedora 25.
BIOS
In the BIOS (F1 to enter during boot), be sure to disable secure boot.
Security > Secure Boot > Secure Boot = Disabled
Also, if your planning to run any kind of virtual machines, make sure you enable the CPU virtualization support.
Security > Virtualization > Intel (R) Virtualization Technology = Enabled
And while your in the BIOS setup you may also want to immediately change the default Function key behaviour. On this ThinkPad by default the function keys will not work as one would expect. When pressing F1 you do not get F1, but you get Mute. To get F1 you need to press Fn-F1 or you first need to enable the FnLk (Fn-ESC). To reverse this behaviour back to how to should be, change the setting in the BIOS.
Config > Keyboard/Mouse > F1-F12 as Primary Function = Enabled
Installation
Nothing special, you can follow the generic Fedora install instructions.
Configuration
Kernel
No special configuration needed
Wayland
This is the default with Fedora 25. For the most part works fine, but there are still a couple of issues that are not specific to this ThinkPad.
For one, the Pen does not work in Wayland mode. Also window placement and full-screen programs are still problematic, in particular if you have more then one monitor. But the list of issues is getting shorter with every new update.
X Server
Works out of the box, but is no longer the default.
If you have the HiDPI display option, it brings with it a whole lot of issues. Most of them are covered here; ArchLinux HiDPI.
Basically everything is quite large as it tries to scale everything 2x when a HiDPI display is detected. In fact a bit too large to my liking. On the archlinux website there are some hints and tips on how to scale things down a bit again, but it is really a hack and far from ideal. After experimenting with various options, I decided to use the default 2x scaling in Gnome, but change the zoom option in the webbrowser to scale everything a bit smaller since that is what I use most.
Also having a HiDPI primary display causes everything on external non-HiDPI displays to appear huge as they will receive the same scaling factor. This is a limitation of the X11 windowing system. The long term solution would be to switch to a Wayland desktop which is able to handle multiple displays with various DPI settings.
Touchscreen & Pen
This remains problematic. First of all, when logging into the Gnome desktop you will get a message that the Wacom touchscreen and pen are not recognised. This can be fixed by creating the following file:
/usr/share/libwacom/isdv4-5040.tablet
# this is for the Wacom pen + touchscreen # as found in the Lenovo Thinkpad X1 Yoga # 14" WQHD display, measuring 310x174mm # pen with 2 buttons, no eraser [Device] Name=Wacom ISDv4 5040 DeviceMatch=usb:056a:5040 Class=ISDV4 Width=12 Height=7 IntegratedIn=Display;System [Features] Stylus=true Touch=true Buttons=0
However, even after this, both the touchscreen and pen operation remains flaky. In particular after suspend operations one or both functions may not work any longer. But even on occasion on a clean boot it may not work. Also when using the default Wayland desktop, the pen does not work at all.
