Installing Fedora 26 on a ThinkPad X1 Yoga
The issues you may encounter with touch and pen input on the X1 Yoga likely are due to a firmware issue. Lenovo has issued an updated firmware . With this update the touch and pen input in Xorg is stable. Only issue is that the firmware update needs to run from Windows.
Note, this does not fix the pen input in xwayland, that is a totally different issue and effects every Wacom device with Wayland right now. While wayland supports tablet devices, the issue is that that only works in combination with GTK3 applications today. Any applications using GTK2, QT or other toolkits will use xwayland, which does not support tablet devices. This including GIMP, Firefox, Chrome, etc.
New in this release
New in this Fedora release, with regards to this model ThinkPad is the following;
- Wacom settings app now also works in Wayland mode
- Screen rotation works out of the box
- brightness sensor works out of the box
- The error that the wacom device is not recognised has been fixed

Tested and Verified on Fedora 26
Information in this section has been tested and verified using Fedora 25.
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
Nothing special, you can follow the generic Fedora install instructions.
No special configuration needed
This is the default starting 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 xwayland 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.
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 solution would be to switch to a Wayland desktop which is able to handle multiple displays with various DPI settings.
Touchscreen & Pen
It is essential that you apply the Lenovo Touch firmware update for the X1 Yoga. Without this update the Pen and Touch is flaky and may stop working even by such simple actions as locking the screen.
Also when using the default Wayland desktop, the pen does not work at all for applications relying on xwayland, which are the majority. This is a known issue. The solution for now is to use Gnome on Xorg.
