Most functionality works out of the box, although a kernel of version 4.3 or higher is necessary for the video card and the wifi adapter and a kernel of version 4.9 or higher for the accelerometer to be recognized. Suspending the machine also works.

¹Pen-buttons can be assigned with xsetwacom, see Wacom tablet#Remapping buttons. Device name is "Wacom Co.,Ltd. Pen and multitouch sensor Pen stylus".

Newer kernels boot without problems and the wifi should be available. If you get a blank screen after booting, the power modes are not supported by your kernel; refer to Troubleshooting.
Booting the install USB
To access the boot menu and BIOS, use "F1". Disable secure boot from the BIOS. UEFI boot mode works fine.
TrackPad works fine with.
See TrackPoint. Sometimes the TrackPoint stops working and dmesg reports a stream of garbage when it is touched. Removing and probing the kernel module solves the problem:
# rmmod psmouse # modprobe psmouse
TouchScreen and Stylus
Touchscreen works with the Wacom driver (package:). Also using the Stylus, the bottom button of the pen is defined as the eraser and the top button works as a middle mouse button
The kernel supports HD Graphics 520 from version 4.3. With default configuration, tearing is apparent when playing videos. DRI3 and glamor are supported. To solve tearing and use DRI3 and glamor, create the file
/etc/X11/xorg.conf.d/20-intel.conf with the following content:
Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "glamor" Option "DRI" "3" Option "TearFree" "true" EndSection
The miniDP port works, at least when used with a VGA adapter. The connected display shows up in xrandr correctly. The HDMI output works with Xorg and xf86-video-intel 1:2.99.917+730.
The microSD-card reader works out of the box.
The Bluetooth adapter works out of the box. It was tested with Android tethering and file transfer.

High CPU usage in idle
If the Thinkpad has unusually high CPU usage in idle then it might be an acpi firmware issue. On Windows this behaviour stops after a regular update. On Linux you can workaround by disabling whatever device is interrupting excessively.
Find the interrupting source:
grep . -r /sys/firmware/acpi/interrupts
This might output something like this:
... /sys/firmware/acpi/interrupts/gpe34: 30289 enabled <-- this causes many interrupts /sys/firmware/acpi/interrupts/gpe35: 3 enabled ...
Disable it (as root, not just sudo):
echo "disable" > /sys/firmware/acpi/interrupts/gpe34
Now the CPU should idle at 0-2% usage.
Unfortunately you have to do that on every startup. A systemd service can do that automatically for you.
[Unit] Description=Disable acpi interrupts [Service] ExecStart=/usr/bin/bash -c 'echo "disable" > /sys/firmware/acpi/interrupts/gpe34' [Install] WantedBy=multi-user.target
Then enable the
disable-interrupts.service systemd unit.
Blank screen after loading kernel
This happens with older kernels because the Intel P-State driver had problems. The workaround is to disable the buggy part of the driver. To achieve this, add
intel_pstate=no_hwp as a kernel parameter. If you use GRUB, edit your
/etc/default/grub file and add the following:
Don't forget to generate the config files with
With a standard Arch-USB-ISO this can be done by pressing the Tabulator-Key on selecting the boot-menu-entry.
Screen rotation not working
Enabling the option
"TearFree" might break screen rotation: xrandr -o left will either result in a blank screen or in an error message (
xrandr: Configure crtc 0 failed). The X.org Intel driver above version 1:2.99.917+641+ge4ef6e9 no longer has this bug. Either upgrade the driver or disable the tear-free playback.
