Installing Fedora 25 on a ThinkPad X1 Yoga

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.

New in this release

New in this Fedora release, with regards to this model ThinkPad is the following;

• Wayland is the default and works better then ever, but still not perfect...
• intel_pstate no longer needs to be disabled
• Touch and Pen input broken on Wayland [1]

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 and Touch does not work in Wayland mode. Also window placement with full-screen programs on a multi-monitor setup is still problematic. 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 may get a message that the Wacom touchscreen and pen are not recognised. This issue is resolved if you have installed the updates.

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 and touch does not work at all for Xorg applications and the Wayland settings app claims no Waycom device is found. This is a known issue. The solution for now is to use Xorg.

ThinkPad Extra keys
