Enable Intel kernel mode setting driver:
After saving the above files, make sure to regenerate your initram image by the command
mkinitcpio -p linux, and follow the steps in kernel parameters.
If you experience that your brightness setting is not restored on resume from suspend, then create config:

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 will 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.

Some models come with an integrated USB UMTS modem.

For it to be recognized by ModemManager, you also need to set the kernel module option to:

Laptop equipped with combined pointing device called UltraNav™. It incorporates small touchpad, three hardware buttons and TrackPoint.
The original configuration renders the touchpad quite useless, as it behaves very jumpily. Ubuntu Bugtracker offers a solution for this issue. Add the following:

Setting e.g. the motion-acceleration value in dconf to 2.8 works nicely.
Keyboard backlight control keys
Due to an issue with the firmware of several ThinkPads the backlight control keys (
F8/F9 on the X230) sometimes do not 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  for details.
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+Space) controls the keyboard lighting.
- GNOME - works out of the box
- Xfce - install , add plugin to panel and reboot. Additionally uses as mixer and for sound level popups
- Handle ACPI events with acpid the hard way. Some functions like
thinkpad-mutemicimplemented in AUR
- See also ThinkPad: Mute button
Supported by fprint out of the box. Used with PAM for authentication, eliminating necessity of password input (logon, sudo). Though it's impossible to turn laptop on and boot Arch right into a desktop environment by just one finger swipe.
X230T (tablet version)
Wacom tablet input
Works out of the box with Wacom tablet.. See
Multitouch screen for the X230t
Some X230t models have a multitouch screen in addition to the Wacom tablet. Works out of the box with.
Thinkpad X230 based on Intel Ivy Bridge (3rd generation) platform which meets OpenCL 1.2 specification. Unfortunately GPU support in Linux is broken, so AUR and AUR will not work. Use CPU-only AUR instead.
OpenCL computation performance differ between CPU and GPU, depending on task. In many cases GPU is preferable. For Core(TM) i5-3210M CPU, which incorporates HD Graphics 4000 GPU:
hashcat -m2500 -b -D 2 --forcereports 3095 H/s (checked in Windows)
hashcat -m2500 -b -D 1reports only 2660 H/s, which is the same as no-OpenCL
In this example OpenCL do not give any advantage and better look for other options like building native binary for your system.
- Main article: Power saving
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.
In order to prolong battery lifespan, especially if laptop always connected to AC power supply, it's possible to keep battery charge between 40-80 %. You can use setting charge thresholds. This tool was superseded by
natacpi, which included in kernel 4.17 and supported by TLP. Though it's possible to change thresholds directly. Values will be stored in battery microcontroller and will survive reboot, but reset if you remove the battery.
# echo 40 > /sys/class/power_supply/BAT0/charge_start_threshold # echo 80 > /sys/class/power_supply/BAT0/charge_stop_threshold
To optimize fan control, install and setup thinkfan. Then use the following configuration:
sensors: - hwmon: /sys/devices/virtual/thermal/thermal_zone0/temp fans: - tpacpi: /proc/acpi/ibm/fan levels: - [0, 0, 60] - [1, 53, 65] - [2, 55, 66] - [3, 57, 68] - [4, 61, 70] - [5, 64, 71] - [7, 68, 32767]
You might want to add
- ["level full-speed", 68, 32767]
It drives the fan at full speed which is normally not possible. It enables the x230 to run in turbo-boost for extended periods of time.
UEFI boot options can be safely (no bricking) set with UEFI Shell v2 (checked with BIOS 2.77 (G2ETB7WW) EC 1.15). Though you can delete any boot variable, so be careful!or
USB UEFI update
All official updates, including Windows utility, Bootable CD and documentation can be found here. You can use AUR to create bootable USB images from the Bootable CD:
$ geteltorito.pl g2uj24us.iso > update.img # dd bs=512K if=update.img of=/dev/sdX
Insert USB stick, reboot and press
F12, choose your USB. Follow the instructions.
Trusted Platform Module
Laptop has dedicated TPM 1.2 chip onboard. It does not looks like it can be upgraded to TPM 2.0. Chip itself disabled by default sometimes, also owner clearing will not appear without Supervisor password set:
- Enter Thinkpad UEFI Setup by pressing
- Set Security > Password > Supervisor password
- Set Security > Security Chip > Security Chip [Active]
- Save settings by pressing F10 and reboot
- Turn laptop off, turn on and UEFI option Security > Security Chip > Clear Security Chip eventually will appear.
Process described in "ThinkPad X230 and X230i User Guide", Chapter 4. Security > Setting the security chip.
- 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.
- UEFI option to clear TPM not working. STM chip datasheet describes physical presence pin, which, probably, can be used as workaround.
