=== Kernel ===
  
Lenovo ThinkPad X230 comes off with a wide range of available configurations. Since Lenovo's acquisition of ThinkPad brand from IBM, it has received lots of negative critics for not maintaining the original quality and compromising the brand itself. Regardless, ThinkPad still is one of the first preferences for many geeks, students (mainly due to student discounts) and Linux users. It is the standard option available in Lenovo's X Series under 12-13 inches display category.
 
=== Hardware ===
 
Below is the short list for this setup. ''After-market RAMs and SSD were bought'' because Lenovo is apparently charging a lot for these.
 
==== Tested Configuration ====
 
{{Note|Below were the tested configurations at the time. If you are interested in more details, see [[#External_links|full review by original tester]] in external links.}}

==== Compatibility ====
 
{{Tip| A closed-source pre-compiled biometric device driver emerged at [http://volker.de/2012/12/fingerprint-gui-und-das-thinkpad-t430s/ volker.de], reported by [https://bbs.archlinux.org/viewtopic.php?pid&#61;1214579#p1214579 Warnaud], successfully tested and found to be functioning by [https://bbs.archlinux.org/viewtopic.php?pid&#61;1214874#p1214874 Bassu].}}
 
Everything works fine out-of-box except the biometric / fingerprint scanner cause of missing driver. X230 comes with a newer model of chip from Upek. Its manufacturer Authentec was contacted and we found that they only support Windows operating system. So for now, the Upek model with PCIE ID 147e:2020 or newer will remain unsupported in Linux until someone writes an open source driver.
 
 
=== System Configuration ===
 
==== Systemd ====
 
Configured as usual with readahead and the below services.
 
* NetworkManager
 
* cups
 
* slim
 
* sshd
 
* syslog-ng
 
* vnstat
 
* cronie
 
* atd
 
Boot time was as roughly ~3 seconds.
 
 
==== Kernel ====
 
{{Note|You may want to run 'linux-ck' instead of the default kernel to conserve power and to fix iwlwifi issue with system sleep and wakeup. See power saving section below}}
 
If you really want to cut power then neither the stock kernel nor the Arch supplied kernel is optimized to run on any laptop efficiently. Try the patched kernels like linux-ck or linux-pf instead.

The {{ic|badblocks}} binary helps fix logical bad blocks if detected by fsck during system startup. First line in modprobe.conf file enables different Intel HD power saving options. To see what each of the parameters does, issue a command {{ic|modinfo i915}}. The second line disables the wifi N mode as Intel wireless driver suffers connection loss due to possible bugs. You can comment on this line if you want to transfer data at wireless N speeds.

After saving the above files, make sure to regenerate your init ram image by the command {{ic|mkinitcpio -p linux}}, and follow the steps in [[kernel parameters]].

{{Note|Using '''i915_enable_rc6&#61;1''' will enable basic power saving with first stage of [http://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface#Processor_states C-state 6] [http://software.intel.com/en-us/blogs/2013/06/03/intel-xeon-phi-coprocessor-power-management-part-2a-core-c-states-the-details (sleeping state)]. The stages vary by level of deepness in the sleep, that can be attained by setting the value of '''i915_enable_rc6''' between 1 to 7 in ascending order as can be seen in its documentation with '''modinfo i915''' command shown above.}}
+
X230 has IPS or TN screen with 125.37 DPI. Refer to [[HiDPI]] page for more information.
{{Warning|Keep in mind that c-state power saving always comes at performance sacrifice and setting a higher value can cause a jittery display or some unexplained and unexpected misbehavior with i915 so you may want to experiment with different values to find out what suites your needs.}}

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.
  
For more information see https://bugzilla.kernel.org/show_bug.cgi?id=51231 .
 
 
==== Power Saving ====
 
{{Tip|<nowiki>The parameter pcie_aspm may not be needed in the more recent 3.9+ kernels</nowiki>}}
 
{{Tip|Don't enable pcie_aspm if '''dmesg <nowiki>| grep -i "doesn't support pcie aspm"</nowiki>''' is true because even if you do, kernel will still keep it disabled}}
 
One option is to use [[Powerdown]] to save power. On this setup, it gave 14+ hours on a 9 cell battery and 6+ hours on plugable 6 cell external battery, with normal usage of cmus, firefox and thunderbird.
 
Power saving kernel parameters in addition to graphics card power saving, are as under.
 
{{hc|grep GRUB_CMDLINE /etc/default/grub|2=<nowiki>
 
GRUB_CMDLINE_LINUX_DEFAULT="quiet ipv6.disable=1 elevator=bfq"
 
GRUB_CMDLINE_LINUX="init=/usr/lib/systemd/systemd pcie_aspm=force acpi_backlight=vendor"
 
</nowiki>
 
}}
 
The parameter {{ic|<nowiki>elevator=bfq</nowiki>}} enables the [[Wikipedia:Brain Fuck Scheduler|Brain Fuck Scheduler]] written by [[Wikipedia:Con Kolivas|Con Kolivas]], part of [[Linux-ck]] and [[Linux-pf]] kernel forks. {{ic|<nowiki>pcie_aspm=force</nowiki>}} forcefully enables the [[Laptop#PCI-e_ASPM|PCIE Active State Power Management]] and {{ic|<nowiki>apci_backlight=vendor</nowiki>}} loads the vendor specific [[Backlight#ACPI]] driver (i.e. thinkpad_acpi) so the brightness keys (Fn + F8 and Fn + F9) work correctly. After editing the grub file, make sure to regenerate your grub configuration by command {{ic|grub-mkconfig -o /boot/grub/grub.cfg}}.
 
 
Note that the {{ic|<nowiki>apci_backlight=vendor</nowiki>}} 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.
 
 
==== Suspension ====
 
{{Warning|If you suspend your system quite often, it is inevitable that you will stumble upon a wireless driver iwlwifi bug with errors 'fifo queues full' in dmesg. It is caused by weird PCIEM power control behaviors and is inhibited in all default kernels (as of writing 3.7.1-3). The only fix is to either enable PREEMPT & BFS with custom compiled kernel or use an optimized kernel like '''[[Linux-ck]]''' as reported by forum user [[User:Bassu|Bassu]]. Default kernels are not suitable for power-conservation anyway. Check https://bbs.archlinux.org/viewtopic.php?pid&#61;1209357 for details.}}
 
Sleep/suspension and unsuspension can be easily managed by systemd without setting it up in Desktop Environment applet or pm-utils. But there are some modules that must be loaded off and on every time the system is put to sleep or is awaken. There's also a need to kill wpa_supplicant by adding {{ic|<nowiki>systemctl restart wpa_supplicant.service</nowiki>}} in below {{ic|<nowiki>sleep.sh</nowiki>}} file. And it is quite fast with systemd anyway.
 
 
{{hc|/usr/lib/systemd/system-sleep/sleep.sh|2=<nowiki>
 
#!/bin/bash
 
if [ "$1" = "pre" ]; then
 
killall -9 wpa_supplicant #nm-applet bug's workaround

/sbin/modprobe -v iwldvm

Put vboxdrv in it too, if you use VirtualBox.

Lenovo ThinkPad X230

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.

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"
EndSection

Setting e.g. the motion-acceleration value in dconf to 2.8 works nicely.

Backlight control keys

Note: On most X230 models, backlight works by default without any issues. Use below only in case of any problems.

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 http://www.example.com link titlefixed 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.

  for i in /sys/bus/$bus/devices/*/power/control; do

Microphone

If the built-in microphone is not detected when using PulseAudio, the steps here may fix the issue: PulseAudio/Troubleshooting#Microphone not detected by PulseAudio.

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.
