Lenovo ThinkPad Edge E430
The following is regarding the Lenovo Thinkpad Edge E430 with 3rd Generation Ivy Bridge Intel processor, released in mid 2012. The E430 is intended to be an affordable, yet still entirely capable business machine. Unlike some of its siblings, it is not to military specs, but is still a well built and quite durable machine. If you are reading this with the intention of ordering yourself this machine, do yourself a favor and opt for the Intel WiFi card for the extra ~$20. The default Realtek works, albiet with a bit of coaxing. Ergo, this article is meant to suppliment the current Installation Guide or Beginners Guide.
With the release of 2012.07.15 and chroot installation process, the documented installation procedure is recommended.

As usual, Realtek devices require a little work. See below.
Realtek Ethernet Compatibility
The Realtek RTL8111/8168B ethernet controller may be relatively unreliable with the r8169 module. Better Ethernet connectivity can be achieved with the official repositories.module. It is available in the
# pacman -S r8168
Following pacman's installation of the module, it may be used to replace the r8169 module. If, while using the live cd, you are informed that pacman needs to be updated, you may ignore it if your only intention is to install the module to facilitate the Arch installation.
# modprobe -r r8169 # modprobe r8168
As a permanent solution, you may blacklist the r8169 module. See Kernel modules for blacklisting procedure.
Don't forget to configure r8168 to load at boot. (If the r8169 module is properly blacklisted, udev will automatically load r8168)
If the Thinkpad in question has the Thinkpad branded WiFi adapter, it semi-works out of the box. There may be a delay preceding any attempted network activity, which can be resolved by disabling the power saving feature. The usual
# ip link wlan0 power off
is not a feature of this particular card. Instead, the over aggressive power saving feature may be turned off upon loading the module on boot.
This may be achieved in two ways.
# echo "options rtl8192ce fwlps=0" >> /etc/modprobe.d/modprobe.conf
Or you may add the following to your kernel boot parameters:
This will turn off the firmware lowpowerstate or fwlps.
If you have not yet ordered your computer, it is advisable to spend the extra money to have it include the Intel Centrino wlan/bluetooth 4.0 card, as it is much better supported. Also, because Lenovo is one of a few comanies that whitelist wlan cards, replacing/upgarding can be challenging, costly, or just downright impossible. For example, this model with the Ivy Bridge is new, ergo the wlan cards with the proper FRU (field replaceable unit) number to pass the whitelist, can not yet (7-31-2012) be found on sites such as ebay. To find what FRU's this machine accepts, go the the Lenovo support site where you should be able to find the necessary documentation.
If, like me, you failed to realize that the wireless card was a horribly supported Realtek, and you are now kicking yourself because of the above mentioned whitelist, you do have an option to change it without ordering a Lenovo specific card. Some kind souls are willing to help others modify their bioses in various ways, one of which is removal of the whitelist. In this thread, I was able to get Serg008 to remove the whitelist for the E430. If you go this route, proceed with caution, as upgrading the bios (and messing up) can render your machine a brick. Also, there are legitimate warranty concerns with unauthorized bios modifications.
SD Card Reader
The card reader will not work out-of-the-box, but thanks to Icetonic, the necessary kernel module, rts5229, can be found from the Realtek website or from the Arch User Repository. Download the tarball and install with makepkg.
Typically with older hardware, one can get the fingerprint reader to function by using one of two open-source fingerprint reader projects. They are [thinkfinger] and [fprint], but unfortunately both are no longer active, so the newest generations are not supported by these projects. Instead, Ubuntu has put together a system that includes drivers included in these previous projects, as well as including proprietary drivers for the newest models. In typical Ubuntu fashion, it is gui driven and appropriately named fingerprint-gui and it is available from the [Arch User Repository].
The fingerprint reader included on the newest generation of Thinkpad E430 is a Upek. To verify the model of the device in a given machine, one may use lsusb.

The trackpoint works out of the box, though scroll wheel emulation button needs a bit of configuring. The following will set the middle Trackpoint button to scroll, though it will also disable the possibility of using it to generate a middle click, to enable middle click with scroll set "Emulate3Buttons" to "true"(01/07/13). Create the file /etc/X11/xorg.conf.d/20-thinkpad.conf as root with the following:
Section "InputClass" Identifier "Trackpoint Wheel Emulation" MatchProduct "TPPS/2 IBM TrackPoint" MatchDevicePath "/dev/input/event*" Option "EmulateWheel" "true" Option "EmulateWheelButton" "2" ## set Emulate3Buttons to true to allow middle click (01/07/13) Option "Emulate3Buttons" "false" Option "XAxisMapping" "6 7" Option "YAxisMapping" "4 5" EndSection
This information was taken from Thinkwiki's page regarding the Trackpoint. You can find it here: http://www.thinkwiki.org/wiki/How_to_configure_the_TrackPoint . Keep in mind that your Trackpoint might be identified by a different "MatchProduct", so you may want to determine the exact indentifier. The easiest way to do this is with the package available in the Official Repositories. Simply run 'hwinfo' as a normal user or root and look for the PS/2 information.
If you so desire, the Thinkfan may be used to control the fan speed. This is probably not necessary as the bios seems to typically handle the fan speed just fine. On top of this, these machines typically have enough power to run fairly cool during typical operation, depending, of course, on what typical is for you, the user.
The thinkpad_acpi kernel module needs to be configured so user space programs can control the fan speed.
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.
Direct fan control can be achieved by using "echo" to apply the desired level. Set the speed as shown in the following examples:
# echo engage > /proc/acpi/ibm/fan # echo level auto > /proc/acpi/ibm/fan # echo level 1 > /proc/etc/ibm/fan
Once thinkpad_acpi has been loaded with fan_control=1, available settings can be displayed like so:
$ cat /proc/acpi/ibm/fan
X Crashes with Dual Monitors
Starting X on an E430 with an Intel Core i7-3612QM and monitors plugged into both the HDMI and VGA ports results in a crash. Only "fix" I've found is to wait until starting X before plugging in one of the monitors.
