== USB Boot ==
Distribution kernel in Debian Lenny 2.6.26-2-686 does not want to boot. Boot works ok with the kernel from backports (2.6.32-bpo.5-686)

== Devices support ==
=== Video === 
{{NOTE| [[Intel_HD_Graphics]] on [[Intel_Core_i3|Core i3]] is not recognized - and probably will not work with native intel xorg driver in Lenny. intel xorg driver supports it since version 2.9.1, but it also requires xorg version 1.6 or newer while Lenny has only version 1.4.2 -> upgrade to Squeeze should help (not tested) }} 

 {{cmduser|cat /var/log/Xorg.0.log.old | grep -i intel}}
 (--) PCI:*(0:2:0) Intel Corporation unknown chipset (0x0046) rev 2, Mem @ 0xf2000000/22, 0xd0000000/28, I/O @ 0x1800/3

xorg then detecs just a general vesa driver: it uses the correct resolution, but has no video acceleration, no external monitor, no dynamic resolution change

==== Brightness control ==== 
Display brightness control with Vesa driver does not work (neither keys nor Gnome controls). thinkpad_acpi requries an option to enable it (modprobe thinkpad_acpi brightness_enable=1) and the /proc/acpi/ibm/brightness appears.
Brightness can be then controlled via Gnome controls or 
 
 {{cmdroot| echo down > /proc/acpi/ibm/brightness}}
 {{cmdroot| echo up > /proc/acpi/ibm/brightness}}

{{key|Fn}}{{key|Home}}/{{key|End}} keys do not work.

==== 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 (http://packages.debian.org/sid/firmware-iwlwifi) 

If firmware is not installed, it complains in the syslog

 iwlagn 0000:02:00.0: iwlwifi-6000-3.ucode firmware file req failed: -2

Enable/disable via {{key|Fn}}{{key|F5}} or via network-manager

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

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

=== Bluetooth === 
works ok, enable/disable only via 
{{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 ===

 [   54.179306] uvcvideo: Found UVC 1.00 device Integrated Camera (17ef:4816)
 [   54.180708] usbcore: registered new interface driver uvcvideo

works ok (ie. luvcview)

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

 [   54.653913] Synaptics Touchpad, model: 1, fw: 7.4, id: 0x1e0b1, caps: 0xd047b1/0xb40000/0xa0000
 [   54.706403] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input6
 [   61.530602] IBM TrackPoint firmware: 0x0e, buttons: 3/3
 [   61.808056] input: TPPS/2 IBM TrackPoint as /devices/platform/i8042/serio1/serio2/input/input8

=== 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 === 
not tested

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

== Power Management == 
=== Suspend to RAM === 
Not working, probably depends on video driver (suspends, but does not resume)

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

=== acpid ===
Acpid does not work without /proc/acpi/event (2.6.29+), force install of new version from lenny backports (http://packages.debian.org/lenny-backports/acpid)

=== 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.
