|style="vertical-align:top" |Below are several ways of configuring the kernel psmouse driver for controlling extended TrackPoint features.
|}

= Configuration using Gnome=
If you are using GNOME, you might want to use [http://tpctl.sourceforge.net/configure-trackpoint.html configure-trackpoint] as a graphical frontend.

= Configuration using HAL =
Modern distributions like Ubuntu 8.10 and Fedora 10 use HAL to configure the input devices. You should no longer make changes to xorg.conf as by default Xorg (through the evdev driver) will let the kernel now handle input devices.

But before you get started on this you should make sure you have all the updates applied from your distro vendor as both Ubuntu 8.10 and Fedora 10 require some additional fixes that you will need.

=== vertical scrolling ===
By default the middle mouse button is that, a middle mouse button, which in Linux is used for the Paste operation.

But you can configure it to act in the same way as in Windows, such that you can use it for vertical scrolling (keep the button pressed and move the TrackPoint up and down to scroll). To accomplish this create the file {{path|/etc/hal/fdi/policy/mouse-wheel.fdi}} as root with the following content:

<pre>
<match key="info.product" string="TPPS/2 IBM TrackPoint">
<merge key="input.x11_options.EmulateWheel" type="string">true</merge>
<merge key="input.x11_options.EmulateWheelButton" type="string">2</merge>
<merge key="input.x11_options.YAxisMapping" type="string">4 5</merge>
<merge key="input.x11_options.XAxisMapping" type="string">6 7</merge>
<merge key="input.x11_options.Emulate3Buttons" type="string">true</merge>
<merge key="input.x11_options.EmulateWheelTimeout" type="string">200</merge>
</match>
</pre>

After this reboot, or restart the hal service and Xorg. You can validate the settings with {{cmd|lshal|}}.

====Reactivate Scrolling after suspend/resume====
Scrolling may be disabled after a resume from suspend.

You can manually reactivate the trackpoint by reloading the {{path|psmouse}} module as root:
:{{cmdroot|rmmod psmouse && modprobe psmouse}}

You can automatically force the pm-utils to reload this module.
Create a file {{path|/etc/pm/config.d/01reload_mouse}} as root with the following content:
<pre>
# reload psmouse to reactivate trackpoint scrolling
SUSPEND_MODULES="${SUSPEND_MODULES:+$SUSPEND_MODULES }psmouse"
</pre>
===Press to Select===
{{Todo|need sample hal config file}}
===Sensitivity and Speed ===
The speed and sensitivity can be adjusted by issuing the following commands (separately) from a root prompt:
<pre>
# echo -n 160 > /sys/devices/platform/i8042/serio1/serio2/speed
# echo -n 255 > /sys/devices/platform/i8042/serio1/serio2/sensitivity
# echo -n 7 > /sys/devices/platform/i8042/serio1/serio2/inertia
</pre>
For speed and sensitivity the range of settings is from 0 to 255.

To make your preferred settings persist at startup, edit /etc/rc.local, as root, and add lines issuing the same commands:
<pre>
echo -n 160 > /sys/devices/platform/i8042/serio1/serio2/speed
echo -n 255 > /sys/devices/platform/i8042/serio1/serio2/sensitivity
echo -n 7 > /sys/devices/platform/i8042/serio1/serio2/inertia
</pre>

=Configuration using xinput=
If you want to modify changes on the fly, you can do so with {{cmd|xinput|}} (part of the optional xorg-x11-apps rpm on Fedora).
Note that these changes are not saved when the xserver is restarted.

To query the available options
xinput list-props "TPPS/2 IBM TrackPoint"

To enable vertical scrolling
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Wheel Emulation" 8 1
xinput set-int-prop "TPPS/2 IBM TrackPoint" "Wheel Emulation Button" 8 2

{{Todo|some other examples}}

=Configuration using sysfs=
Another way to modify changes on the fly, is echoing values directly into special files in sysfs.

{{NOTE|
The examples shown below are valid for ThinkPads with both TrackPoint and Touchpad, in which case the sysfs path is {{path|/sys/devices/platform/i8042/serio1/serio2}}.

If however you have a ThinkPad without Touchpad, or with the Touchpad disabled in the BIOS, the sysfs path needs to be changed to {{path|/sys/devices/platform/i8042/serio1}} instead (notice the missing serio2 at the end).}}

If you want to set the sysfs parameters at boot, you can use the [http://linux-diag.sourceforge.net/Sysfsutils.html sysfsutils] and put the preferred value in /etc/sysfs.conf.

===Press to Select===
Press to Select allows you to tap the control stick which will simulate a left click. You can enable this feature by typing the following in to a terminal (you may need to be root):

:{{cmdroot|echo -n 1 > /sys/devices/platform/i8042/serio1/serio2/press_to_select}}

Press to Select should now be enabled. You can disable it in a similar manner:

:{{cmdroot|echo -n 0 > /sys/devices/platform/i8042/serio1/serio2/press_to_select}}

You can use this script to automate the operation

#!/bin/bash
if [ "$1" = "1" ]; then
echo "Turning on tap on TrackPoint"
echo -n 1 > /sys/devices/platform/i8042/serio1/serio2/press_to_select
exit 0
fi
if [ "$1" = "0" ]; then
echo "Turning off tap on TrackPoint"
echo -n 0 > /sys/devices/platform/i8042/serio1/serio2/press_to_select
exit 0
fi
echo -n "Tap status: "
cat /sys/devices/platform/i8042/serio1/serio2/press_to_select

===Sensitivity & Speed===
Adjusting the speed and sensitivity of the TrackPoint requires echoing a value between 0 and 255 into the appropriate file. For example, for a speed of 120 and a sensitivity of 250, type the following into a terminal:

:{{cmdroot|echo -n 120 > /sys/devices/platform/i8042/serio1/serio2/speed}}
:{{cmdroot|echo -n 250 > /sys/devices/platform/i8042/serio1/serio2/sensitivity}}

Feel free to experiment with your settings until you find a combination that is comfortable.

When you satisfy your setting, add the two lines into /etc/rc.d/rc.local in order to avoid restoring the default setting every time the system reboots.

===Vertical Scrolling===
No sysfs entry exists for vertical scrolling in kernels after 2.6.11.

The feature was removed as it was not a hardware feature, but rather emulating a scroll action in software and as such did not belong in the kernel.
Instead the scroll feature of the Xserver should be used, which can be activated with HAL or xinput as described above.

=Configuration using the X server (old Xorg only)=
{{NOTE|This only applies to old distributions with Xorg versions that did not yet use evdev. For modern distributions use one of the other methods}}
The scroll setting has been removed from the trackpoint driver in kernel versions 2.6.11 and above. Scroll emulation should now be handled in the X server.

A nice side effect of that is, that middle button scrolling applies to any mouse and not just the TrackPoint interface, which can be a quite handy feature for desktop computers or people who prefer to use an external mouse, especially when scrolling through long lists or needing to use horizontal scrolling with a mouse which has only a vertical scroll wheel.

The necessary functionality, known as "EmulateWheelTimeout" allowing to use button 2 for a middle click, wasn't implemented in Xorg prior to 6.9/7.0. However, there was a patch included in most distributions packages of Xorg, which was announced [http://www.mail-archive.com/devel@xfree86.org/msg03333.html here]. You can find an updated version of the package in the experimental branch of {{Debian}} or try to build the mouse driver yourself with the information in the announcement. This has successfully been tried with FC3's 6.8.2 packages.

Once this functionality is in the X.org, add these lines to your TrackPoint configuration section in {{path|/etc/X11/xorg.conf}}:

Option "EmulateWheel" "on"
Option "EmulateWheelButton" "2"

It may also be necessary to add these lines:

Option "YAxisMapping" "4 5"
Option "XAxisMapping" "6 7"

which specify which buttons are mapped to motion in the vertical (Y) and horizontal (X) directions, respectively, in wheel emulation mode (see http://www.xfree86.org/current/mouse.4.html).

{{HINT| Use the program "xev" to see, what mouse button identifiers are sent by your mouse/touchpad/trackpoint.<br />You might want to try: "xev | grep button"}}
{{HINT| If it does not work see if evdev is installed and remove it. On gentoo do the following:<br />
eix xf86-input-evdev<br />
emerge -C xf86-input-evdev<br />
and then remove the evdev flag in make.conf INPUT_DEVICES}}

So, a complete mouse section, that implements this nicely and works very well on my R51, even with a simultaneously connected USB mouse, looks like that (tried out today, 20th of September, 2006 on Dapper):

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ExplorerPS/2"
Option "Emulate3Buttons" "on"
Option "Emulate3TimeOut" "50"
Option "EmulateWheel" "on"
Option "EmulateWheelTimeOut" "200"
Option "EmulateWheelButton" "2"
Option "YAxisMapping" "4 5"
Option "XAxisMapping" "6 7"
Option "ZAxisMapping" "4 5"
EndSection

The mappings for Y and Z are the same, since the "Z-Axis" refers to actual hardware scrolling wheels which usually scroll the screen along the Y-Axis. If there is no hardware scrolling wheel present, horizontal and vertical scrolling using the TrackPoint work fine without the Z-Axis line.

Now restart X and hold down button 2 and move the mouse to scroll, or just press and release button 2 for a middle click.

To make this work with the synaptics driver for the touchpad, you can add
Option "GuestMouseOff" "1"
to the synaptics device section. This will make the synaptics driver ignore the Trackpoint, so it will be handled by the mouse driver. This allowed me to disable the touchpad while making the TrackPoint work like it should.

{{NOTE| With the above mouse section in my xorg.conf all this works like a charm:
*I can press the wheel on my external USB mouse and move the mouse up and down for scrolling
*or I can just use the wheel on the external mouse for scrolling
*or pressing the MMB button of the trackpoint and use the trackpoint for scrolling.
*Even horizontal scrolling works automagically in Konqueror, for Firefox/Opera see below.

Simultaneously I can use
*a press on the external mouse's wheel
*or the MMB of the trackpoint

for pasting the buffer. Lovely! :) }}

{{HINT| If you don't use the middle-mouse-button for pasting and sometimes pasting things by mistake while scrolling (witch is really odd) simply set the "EmulateWheelTimeOut" to "1" as a (bloody) workaround. Middle click will only possible with pressing left and right button simultaneously!}}
=Application specific tweaks=
===Configure Opera for using trackpoint horizontal scrolling===
To fix horizontal scrolling in Opera, you need to edit the configfile <tt>standard_mouse.ini</tt> in e.g. /usr/share/opera/ini/ (Debian) or /opt/opera/share/opera/ini/ (Gentoo) and comment out the following lines
<pre>
Button6 = Back
Button7 = Forward
</pre>
so they look like that
<pre>
;Button6 = Back
;Button7 = Forward
</pre>
Remember, Button6 and Button7 do not so coincidental correspond with our X configuration we know from above:
<pre>
Option "YAxisMapping" "6 7"
</pre>
After this change you will be able to scroll vertically and horizontally with your middle button.

===Firefox 3 tweaks===
These settings make Firefox on Linux behave more like the Windows version. They were tested on an out of the box Fedora 10 system on a Thinkpad T61. Go into about:config, and set the following:

middlemouse.paste = false
middlemouse.contentLoadURL = false
general.autoScroll = true

=== ThinkPad 11a/b/g Wireless LAN Mini Express Adapter ===
This is a WiFi Adapter that is installed in a Mini-PCI Express slot

=== Features ===
* Chipset: Atheros AR5006EX (As printed on card AR5BXB6) or AR5212
* Integrated Mac Processor and Radio Chip: Atheros 5423
* IEEE Standards: 802.11a, 802.11b, 802.11g
* PCI ID: 168c:1014

|}

=== IBM Partnumbers ===
IBM Option PN (US): 40Y7026

=== Linux WiFi driver ===
Use the [[Madwifi]] driver. This driver has support for Atheros rev 0x0024 support since svn revision 2360.

OR (not recommended)

get the driver from http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-52527 and use ndiswrapper

=== Hardware switch ===

Some ThinkPads have a hardware switch that must be in the '''on''' position for the radio to work, regardless of driver state:

[[Image:Wireless-switch.png|(ThinkPad R60 radio switch in the ON position)]]

(Note: This may not always be the case. On at least one T60, model 2007-62U with Atheros AR5212, using Ubuntu Edgy, Feisty, and Debian Testing, with the MadWifi driver, the wireless switch has no effect. Wireless operates with the switch in either position. But there's an [http://article.gmane.org/gmane.linux.acpi.ibm-acpi.devel/137 experimental patch] which adds support of the switch to [[ibm-acpi]].)

=== T60 WiFi LED ===

Problem: The WiFi LED on the T60 isn't enabled by default on bootup.

Solution: As root edit /etc/rc.local by adding the following command at the bottom:

'''echo -n 1 > /proc/sys/dev/wifi0/ledpin;'''

Save your changes, afterwards on every boot up the WiFi LED will be enabled.

Note:This has been verified on a T60 1953-D7U running Fedora 7 Linux, however this
should work on most Laptop-OS configurations.

=== X61 WiFi LED blink on transfer===

Howto make the wifi led blink when there is network traffic.
I've only tested this on an X61 with AR5212 802.11abg - AR5BXB6 on Debian/Ubuntu

sysctl -w dev.wifi0.ledpin=1
sysctl -w dev.wifi0.softled=1 //change the 1 to anything 1-9 for a more responsive blink

If you would like for this to occur on boot, add

dev.wifi0.ledpin=1
dev.wifi0.softled=1

to

/etc/sysctl.conf

=== ThinkPads this card may be found in ===
* {{T60}}, {{T60p}}, {{T61}}
* {{R60}}
* {{X60}}, {{X60s}}
* {{Z60t}}, {{z61m}}
