View source for Installing Debian on an X230

These notes refer to installation of Debian 7 (Wheezy) on an {{X230}} system, model 2306-CTO.

== Thinklight and backlit keyboard ==
Both of these features work as expected out of the box.

== Brightness ==

Brightness control works using the expected Fn + function keys, however only 6 levels are detected. 

If you use Gnome 3, you can use the [https://extensions.gnome.org/extension/231/brightness-control/ Brightness Control] extension to control up to 16 levels of brightness.

Another way consists of adding the {{bootparm|acpi_backlight|vendor}} kernel parameter to the boot options{{footnote|1}} :
# Edit the {{path|/etc/default/grub}}  file:<BR/>{{cmduser|gksudo gedit /etc/default/grub}}
# Append {{bootparm|acpi_backlight|vendor}} to the default kernel parameters:<BR/>GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
# Update GRUB:<BR/>{{cmduser|sudo update-grub}}

Reboot to make the changes effective.

{{NOTE|Although more brightness levels will be supported, the Gnome indicator will not display the brightness level acurately. See the bug report link below.}}

== UltraNav scrolling ==
The UltraNav scrolling is not supported out of the box. Normally moving the Trackpoint while pressing the middle-button (identified by blue dots, just above the trackpad) should provide scrolling motions for applications that support it (the web browser for example).

=== Using a configuration file ===
This has been verified to work in Debian 7 (Wheezy):

# Edit {{path|/usr/share/X11/xorg.conf.d/20-thinkpad-trackpoint.conf}} 
# Insert the following:
 Section "InputClass"
    Identifier  "ThinkPad TrackPoint"
    MatchProduct    "TPPS/2 IBM TrackPoint"
    MatchDevicePath "/dev/input/event*"
    Option      "EmulateWheel"      "true"
    Option      "EmulateWheelButton"    "2"
    Option      "XAxisMapping"      "6 7"
    Option      "YAxisMapping"      "4 5"
 EndSection

The UltraNav button will work as expected after rebooting your system.

=== Using gpointing-devices-settings (broken) ===
{{WARN|This used to work - now it doesn't!}} 

To enable this functionality, the '''gpointing-devices-settings''' is mentioned in several places as a way to configure it. Unfortunately it seems with Gnome 3 it doesn't anymore.

Once installed, look for the '''Pointing devices''' application, or launch '''gpointing-devices-settings''' from command line. Select the TrackPoint device, check the '''Use wheel emulation''' option and choose button #2.

Also make sure to check both options for vertical and horizontal scrolling if you will be using them.

== Wireless ==
Wireless does not work with 100% free drivers out of the box. The internal half mini PCIe card can't be replaced by a compatible card as this system uses BIOS whitelisting. There isn't a modified BIOS available yet (as of Jan 15 2013).
* [[Problem with unauthorized MiniPCI network card]]

Debian Squeeze and Wheezy '''non-free''' component includes [http://wiki.debian.org/iwlwifi support for such non-free drivers installation].

As a workaround, an external USB adapter such as those sold by [http://libre.thinkpenguin.com ThinkPenguin] can be used. When using such external adapters, consult ThinkPenguin's support as even firmware published under free licenses is not installed by default and may require manual compilation or installation.

== Fingerprint reader ==
The fingerprint reader does not work with 100% free drivers out of the box. 

== Battery ==
Several optimizations are needed to maximize battery time. Most apply to any GNU/Linux distributions, except for running Libre kernels. See [https://trisquel.info/en/wiki/optimizing-battery-time Optimizing battery time] on the Trisquel wiki.
