Lenovo Thinkpad Yoga 260


Overview

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. Suspending the machine also works. The accelerometer does not show up.

Installation

In order to boot with a current kernel, you need to pass intel_pstate=no_hwp as kernel parameter. With a standard Arch-USB-ISO this can be done by pressing the Tabulator-Key on selecting the boot-menu-entry.

If you cannot manage to utilize the kernel parameter, installation gets difficult because you need to choose an old kernel (e.g., installation media from 2015.08 or before) and you do not have network access without additional RJ45 adapter, as the laptop does not have an RJ45 port.

Booting the install USB

To access the boot menu and BIOS, use "F1". Disable secure boot from the BIOS. UEFI boot mode works fine.

Network connection

If you have a OneLink+ dock or a USB Ethernet adapter, you can have wired connection. Otherwise, you need a workaround. Since you cannot edit the boot options on the USB stick, to pass intel_pstate=no_hwp to the kernel, you can either remaster the install ISO or install a bootstrap Linux, upgrade its kernel, edit its boot parameters, and continue installing Arch from an existing Linux. The latter was tested with Linux Mint 17.3 acting as the bootstrap system.

Boot manager

The default ESP partition has ample space (260 MByte). Irrespective of which boot manager you choose, remember to add intel_pstate=no_hwp as a kernel parameter. If you use GRUB, edit your /etc/default/grub file and add the following:

GRUB_CMDLINE_LINUX="intel_pstate=no_hwp"

Don't forget to generate the config files with grub-mkconfig.

Configuration

TrackPad

TrackPad works fine with xf86-input-synaptics.

TrackPoint

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: xf86-input-wacom). Also using the Stylus, only one of the two buttons on the pen is usable.

Video

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

Enabling the option "TearFree", however, breaks screen rotation: xrandr -o left will either result in a blank screen or in an error message (xrandr: Configure crtc 0 failed).

The miniDP port works, at least when used with a VGA adapter. The connected display shows up in xrandr correctly..

Card reader

The microSD-card reader works out of the box.
