=== ThinkPad Bluetooth with Enhanced Data Rate (BDC-2) ===
This is a USB Bluetooth Adapter that is installed in a [[CDC slot]] in the screen assembly.
=== Features ===
* Chipset: Broadcom
* Model: BCM2045B
* USB VID/PID: 0A5C:2110

|}

=== IBM Partnumbers ===
IBM FRU PN: 39T0497

=== Linux Driver ===

The Bluetooth adapter uses the '''hci_usb''' driver {{kernelconf|CONFIG_BT_HCIUSB||||||}}.

One can enable Bluetooth by pressing {{key|Fn}}{{key|F5}}. If this doesn't work, you can load the [[ibm-acpi|ibm_acpi]] or [[ibm-acpi|thinkpad_acpi]] kernel module and run the following command with root privileges:

{{cmdroot|echo "enable" > /proc/acpi/ibm/bluetooth}}

When Bluetooth is enabled, the Bluetooth-logo LED will light up and executing {{cmdroot|lsusb}} will show an entry mentioning "Broadcom"

On the T60, T61 and Z61, the Wireless kill-radio switch disables both WiFi and Bluetooth (Verified on a ThinkPad Z60m, Z61t, T60, and T61).

Installing Ubuntu on a ThinkPad X22

2007-08-19T00:08:18Z

Gawelo: /* Driver */

== Ubuntu 7.04, Feisty ==

Ubuntu 7.04 (Feisty) Just Works on the X22.

=== Video ===

==== Driver ====

By default, the installation select the "ati" driver, everything is fine but if you select "radeon" instead, XGL give less error.

Check it by 'grep "WW\|EE" /var/log/Xorg.0.log'

The xorg.conf that works for X22 should look like this:

Section "Device"
Identifier "Card0"
VendorName "ATI Technologies Inc"
BoardName "Radeon Mobility M6 LY"
Driver "radeon"
BusID "PCI:1:0:0"
EndSection

Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "Card0"
Monitor "Generic Monitor"
DefaultDepth 16
SubSection "Display"
Depth 16
Modes "1024x768"
EndSubSection
EndSection

==== DRI ====

By default in the section of your screen, the DefaultDepth is 24 but X22 don't have enough video memory to enable this setting, change it to 16 and DRI will be ok. You just double your FPS under glxgears :D

=== Power saving ===

Reporting by powertop, gnome is not so good for battery life and ibm_acpi neither, maybe you have to choose between comfort and some shortcuts ...

=== Emulate wheel ===

In /etc/X11/xorg.conf

Section "InputDevice"
Option "EmulateWheel" "on"
Option "EmulateWheelButton" "2"
Option "YAxisMapping" "4 5"
EndSection

== Ubuntu 5.10, Breezy ==

{{Ubuntu}} 5.10 (Breezy) has problems with suspend to disk (hibernate) and suspend to ram (sleep) on the {{X22}}.

=== Suspend ===

However, [[Software Suspend 2]] works well, and is fast enough to be a useful replacement for sleep.
The following howto explains the installation process:
http://ubuntuforums.org/showthread.php?t=75443

NOTE: during kernel configuration, in device drivers -> ata be sure to say N to 'generic/default IDE chipset support', and Y to 'Intel PIIXn chipsets support'. This will allow for much faster suspend.

To enable suspend by pressing {{key|Fn}}{{key|F12}} (instead of the power button recommended in the howto), edit
{{path|/etc/acpi/events/ibm-hibernatebtn}} and change the action line to read
action=/usr/sbin/hibernate

== Ubuntu 5.04, Hoary ==

Ubuntu 5.04 (Hoary) Just Works on the X22.

=== ACPI ===

However, ACPI suspend to ram is disabled by default. To enable it, edit {{path|/etc/default/acpi-support}} and uncomment the line
<code>
ACPI_SLEEP=true
</code>
This will allow suspend by pressing {{key|Fn}}{{key|F4}}

By default, closing the lid blanks the screen, but does not suspend. To suspend on lid close, edit
{{path|/etc/acpi/events/lidbtn}} and change the action line to read
<code>
action=/etc/acpi/sleep.sh
</code>
