Tested and Verified on Fedora 23
Information in this section has been tested and verified using Fedora 23.
Installation
By default, the installation will hang immediately after the bootloader with a black screen. It is necessary to edit the boot options and add "intel_pstate=disable" to the end of the line of options.
After this, installation is straight forward; you can follow the generic Fedora install instructions.
What you may notice is that during installation on the HiDPI display that everything is very small, and that WIFI does not work. For both of these it is necessary to upgrade the kernel and linux-firmware modules after installation.
Configuration
Kernel
As root, edit /etc/default/grub and adding the option intel_pstate=disable which will prevent a hang at boot. After adding this, update the grub configs with the following (assuming default uEFI setup);
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
There is a work around for this BIOS bug in the 4.6 kernel, which is not available for Fedora 23 at this point.
X Server - Intel HD Graphics
Works out of the box, but HiDPI is not detected until you install a more recent kernel.
ThinkPad Extra keys
ThinkPad keys are handled by a mixture of the thinkpad_acpi, acpi button, acpi dock and acpi video drivers.
