Fans

The thinkpad_acpi kernel module needs to be configured so user space programs can control the fan speed.

/etc/modprobe.d/modprobe.conf
options thinkpad_acpi fan_control=1

The thinkfan configuration file also needs to know how to set the fan speed. Replace the default sensor settings with the following.

/etc/thinkfan.conf
sensor /sys/devices/platform/coretemp.0/temp1_input

Sound

To make sound work, make sure all channels are unmuted via alsamixer or similar, and configure the snd-hda-intel module to load specifically for a thinkpad.

/etc/modprobe.d/modprobe.conf
options snd-hda-intel model=thinkpad

Track Point

Setting

Create 20-thinkpad.conf under /etc/X11/xorg.conf.d/.

Section "InputClass"
        Identifier      "Trackpoint Wheel Emulation"
        MatchProduct    "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint|ThinkPad USB Keyboard with TrackPoint|USB Trackpoint pointing device|Composite TouchPad / TrackPoint"
        MatchDevicePath "/dev/input/event*"
        Option          "EmulateWheel"          "true"

Configuration Tool

The GPointing Device Settings is a great tool for configuring the Track Point. You may install it via AUR: gpointing-device-settingsAUR.
