View source for Installing Debian 6.0 (Squeeze) on a ThinkPad X201i

== Summary ==
X201i seems to be a very good choice for Debian Squeeze - all features I have tested works there out of the box :-)

== HW Overview ==

== USB Boot ==
Distribution kernel in Debian Squeeze 2.6.32-5-686 boots fine

== Devices support ==
=== Video === 
Works out of the box, including 2D acceleration, dynamic resolution change (randr), detecting external monitor, dual head display

==== Brightness control ==== 
Works out of the box through Gnome controls, incl. {{key|Fn}}{{key|Home}}/{{key|End}}.

==== Intel Wireless Display ==== 
All Core i3 processors have a nice feature to display the video over WiFi connection, see e.g. 
http://www.intel.com/consumer/products/technology/wirelessdisplay.htm, which is even not mentioned in the X201i specifications. However it needs some software support and it seems none at least thinks about it for Linux (http://scoop.intel.com/2010/06/thinking-about-getting-an-intelr-wireless-display-pc-get-the-netgear-push2tv-adapter-for-only-50.php , http://www.google.com/search?q=linux+%22intel+wireless+display%22)

=== WLAN === 
module iwlagn + firmware iwlwifi-6000-4.ucode ie. from firmware-iwlwifi_0.27_all.deb 

Enable/disable via {{key|Fn}}{{key|F5}} or via network-manager, hardware switch ok

=== Ethernet ===
module e1000e, works ok

=== Sound ===
module snd-hda-intel works ok, incl. headphones

=== Bluetooth === 
works ok, enable/disable via Gnome controls or 
{{cmdroot|echo "enable" > /proc/acpi/ibm/bluetooth}}
{{cmdroot|echo "disable" > /proc/acpi/ibm/bluetooth}}

=== ThinkLight === 
works ok, turn on/off via {{key|Fn}}{{key|PgUp}} or /proc/acpi/ibm/light

=== WebCam ===

 [  107.091155] uvcvideo: Found UVC 1.00 device Integrated Camera (17ef:4816)
 [  107.093565] usbcore: registered new interface driver uvcvideo

works ok (ie. luvcview)

=== TouchPad/TrackPoint ===
work both ok, incl. touchpoint page scrolling on the right side

 [  107.595394] Synaptics Touchpad, model: 1, fw: 7.4, id: 0x1e0b1, caps: 0xd047b1/0xb40000/0xa0000
 [  107.652484] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input8
 [  114.629105] IBM TrackPoint firmware: 0x0e, buttons: 3/3
 [  114.922029] input: TPPS/2 IBM TrackPoint as /devices/platform/i8042/serio1/serio2/input/input9

=== Keyboard ===
Hint: In Gnome select keyboard type IBM ThinkPad - special keys like "next/prev page" then work

Check the page [[How_to_get_special_keys_to_work|How to get special keys to work]] to setup other special and/or {{key|Fn}} keys.

=== Fingerprint reader ===
not tested

=== Fixed line modem === 
not tested

=== Security Chip === 
not tested

=== Active Protection System === 
install packages tp-smapi-dkms (with kernel headers available it creates a tp-smapi kernel module) and hdapsd. starting of hdapds deamon works fine (check more on [[How to protect the harddisk through APS]])

 hdaps: initial mode latch is 0x05
 hdaps: setting ec_rate=250, filter_order=2
 hdaps: device successfully initialized.
 input: ThinkPad HDAPS joystick emulation as /devices/virtual/input/input15
 input: ThinkPad HDAPS accelerometer data as /devices/virtual/input/input16
 hdaps: driver successfully loaded.

=== Card Reader === 
works ok (tested SD card)

== Power Management == 
=== Suspend to RAM === 
Works out of the box

=== Suspend to disk === 
Works out of the box

=== acpid ===
Works out of the box

=== cpufreq === 
Frequence scaling via cpufreq ok

 {{cmduser|cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies}}
 2399000 2266000 2133000 1999000 1866000 1733000 1599000 1466000 1333000 1199000 1066000 933000

=== CPU enable/disable === 
CPU enabling/disabling works via 

 {{cmdroot|echo 0 > /sys/devices/system/cpu/cpu2/online}}
 {{cmdroot|echo 1 > /sys/devices/system/cpu/cpu2/online}}

but even turning off 3 of them does not seem to influence the power consumption when running on battery.
