Configuration
Kernel
/etc/mkinitcpio.conf
MODULES="i915"
After saving the above files, make sure to regenerate your init ram image by the command mkinitcpio -p linux
, and follow the steps in kernel parameters.
Screen
X230 has IPS or TN screen with 125.37 DPI. Refer to HiDPI page for more information. It can be set with command xrandr --dpi 125.37
using .xinitrc or other autostarts.
See Intel for driver choice.
Brightness
If you experience that your brightness setting is not restored on resume from suspend, then create /usr/share/X11/xorg.conf.d/20-intel.conf
with the following content.
/usr/share/X11/xorg.conf.d/20-intel.conf
Section "Device" Identifier "card0" Driver "intel" Option "Backlight" "intel_backlight" BusID "PCI:0:2:0" EndSection
Touchpad
The original configuration renders the touchpad quite useless, as it behaves very jumpily. Ubuntu Bugtracker offers a solution for this issue. Add the following
/etc/X11/xorg.conf.d/50-synaptics.conf
Section "InputClass" Identifier "touchpad" MatchProduct "SynPS/2 Synaptics TouchPad" # MatchTag "lenovo_x230_all" Driver "synaptics" # fix touchpad resolution Option "VertResolution" "100" Option "HorizResolution" "65" # disable synaptics driver pointer acceleration Option "MinSpeed" "1" Option "MaxSpeed" "1" # tweak the X-server pointer acceleration Option "AccelerationProfile" "2" Option "AdaptiveDeceleration" "16" Option "ConstantDeceleration" "16" Option "VelocityScale" "20" Option "AccelerationNumerator" "30" Option "AccelerationDenominator" "10" Option "AccelerationThreshold" "10" # Disable two fingers right mouse click Option "TapButton2" "0" Option "HorizHysteresis" "100" Option "VertHysteresis" "100" # fix touchpad scroll speed Option "VertScrollDelta" "500" Option "HorizScrollDelta" "500" EndSection
Setting e.g. the motion-acceleration value in dconf to 2.8 works nicely.
Backlight control keys
Due to an issue with the firmware of several ThinkPads the backlight control keys (fn + F8/F9 on the X230) don't work correctly. Setting the brightness via e.g. the GNOME power control panel or altering the brightness value in sysfs is possible.
The issue can be temporarily and partially fixed in adding the acpi_osi="!Windows 2012" kernel parameter. The fix is partial in that only 8 steps are accessible via the keys. See [1] for details.
Suspend to ram
There is an issue with system shutdown with power saving tools that cannot distinguish sys devices. You will need to add to the systemd shutdown trigger on this machine or else you'll get a system reboot when you shutdown the machine. Put this in /etc/rc.local.shutdown and update and enable its service, if not already.
/etc/rc.local.shutdown
#!/bin/bash # /etc/rc.local.shutdown: Local shutdown script. # A script to act as a workaround for the bug in the runtime power management module, which causes thinkpad laptops to restart after shutting down. # Bus list for the runtime power management module. buslist="pci i2c usb" for bus in $buslist; do for i in /sys/bus/$bus/devices/*/power/control; do echo on > $i done done

UMTS Modem
Some models come with an integrated USB UMTS modem.
$ lsusb -d 0bdb:1926
Bus 003 Device 004: ID 0bdb:1926 Ericsson Business Mobile Networks BV H5321 gw Mobile Broadband Driver
In order for it to work with NetworkManager, you will need to install ModemManager from the official repositories.
For it to be recognized by ModemManager, you also need to set the kernel module option to:
/etc/modprobe.d/umts-modem.conf
options cdc_ncm prefer_mbim=N
Fan control
To optimize fan control, install and setup thinkfan. Then use the following configuration:
/etc/thinkfan.conf
tp_fan /proc/acpi/ibm/fan hwmon /sys/class/thermal/thermal_zone0/temp (0, 0, 60) (1, 53, 65) (2, 55, 66) (3, 57, 68) (4, 61, 70) (5, 64, 71) (7, 68, 32767)
USB BIOS update
You can use geteltoritoAUR to create bootable USB images from the BIOS update ISO. It is as easy as:
$ geteltorito.pl g2uj24us.iso > update.img # dd bs=512K if=update.img of=/dev/sdX
Power Saving
Follow the main article: Power saving
Power saving kernel parameters in addition to graphics card power saving, are shown below. acpi_backlight=vendor
loads the vendor specific Backlight#ACPI driver (i.e. thinkpad_acpi) so the brightness keys (Fn + F8 and Fn + F9) work correctly.
Note that the acpi_backlight=vendor
kernel option also works with the standard Arch kernel (currently 3.7.10-1) and has the additional bonus that (Fn + spacebar) controls the keyboard lighting.
TLP
Users of TLP need to pay attention to a hardware bug according to which it is recommended to only use either the upper or lower charging threshold. The following configuration is recommended by the developer of TLP.[1]
/etc/default/tlp
START_CHARGE_THRESH_BAT0=67 STOP_CHARGE_THRESH_BAT0=100
x230T (tablet version)
Multitouch screen for the x230t (tablet version)
Works out of the box with xf86-input-libinput.

Works out of the box with xf86-input-wacom. See Wacom tablet
Not Working
- Microphone on-off key does not work out of the box
- There is a BIOS bug that gets in the way of the boot process with LUKS and full-disk encryption. The user is stuck at the "Loading initial ramdisk" step, and does not see a password prompt to unlock the encrypted device. You can actually enter your password at this step, and boot-up will continue. However, updating the BIOS will resolve this completely.
