==General Configuration==
The configuration options are reflected by the files you can find in {{path|/sys/devices/platform/i8042/serio0/serio2}}. See the [[Patch to enable advanced trackpoint configuration|TrackPoint driver page]] for a complete list.
Configuration is done by echoing the appropriate values into these special files.

==Most common Features==
The most common settings are '''Press to Select''', '''sensitivity''', '''speed''' and '''scrolling'''.

===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/serio0/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/serio0/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/serio0/serio2/speed}}
:{{cmdroot|echo -n 250 > /sys/devices/platform/i8042/serio0/serio2/sensitivity}}

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

===Scrolling===
====Using a kernel prior to 2.6.11====
The scrolling action is essentially the same as is used in the TrackPoint Windows drivers. To enable this feature, type the following in to a terminal (you may need to be root):

:{{cmdroot|echo -n 1 > /proc/trackpoint/scroll}}

Then press the middle button and push the stick up and down to scroll. Similarly, to disable scrolling:

:{{cmdroot|echo -n 0 > /proc/trackpoint/scroll}}

====Using the X server (kernel 2.6.11+)====
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.

The necessary functionality, known as "EmulateWheellTimeout" 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, which change axis orientation:

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

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.

===== EmulateWheelTimeout temporarily broken (-> fix for Ubuntu Dapper) =====

Unfortunately, there was a regression so that EmulateWheelTimeout was broken in X.org 6.9.0, and fixed
on March 20th, 2006.
You can see the [https://bugs.freedesktop.org/show_bug.cgi?id=5071 primary bug report] here, and also reports on the [http://qa.mandriva.com/show_bug.cgi?id=21196 Mandriva] and [http://lists.debian.org/debian-x/2006/01/msg00249.html Debian] packages.

Unfortunately, this bug is still present in Ubuntu Dapper Drake's xserver-xorg-input-mouse package (version 1.0.3.1+cvs.20060109-0ubuntu2)!
Use the following procedure to make it (middle button scrolling & middle button pasting) work:

:{{cmduser|cd /desired/path && mkdir tmp && cd tmp}} (create temporary directory somewhere)
:{{cmduser|sudo nano /etc/apt/sources.list}} (insert/uncomment the deb-src lines, save and exit)
:{{cmduser|sudo apt-get update}}
:{{cmduser|apt-get source xserver-xorg-input-mice}} (in order to get the source code)
:{{cmduser|sudo aptitude install xserver-xorg-dev}} (this package and the packages it depends on are needed in order to compile the source code, use aptitude for easy removal later on)
:{{cmduser|cd xserver-xorg-input-mouse-1.0.3.1+cvs.20060109/}}
:{{cmduser|wget http://librarian.launchpad.net/2639933/xserver-xorg-input-mouse_1.0.3.1+cvs.20060109-0ubuntu2.debdiff}} (downloads the patch that fixes the bug)
:{{cmduser|patch -p1 < xserver-xorg-input-mouse_1.0.3.1+cvs.20060109-0ubuntu2.debdiff}} (applies the bug fix)
:{{cmduser|fakeroot dpkg-buildpackage}} (rebuilds the package... watch out for errors and install other missing packages)
:{{cmduser|sudo dpkg -i ../xserver-xorg-input-mouse_1.0.3.1+cvs.20060109-0ubuntu2_i386.deb}} (installs the rebuilt built package)
:{{cmduser|sudo aptitude remove xserver-xorg-dev}} (removes the packages needed to rebuild the package)

Hope it works for you, it did work for me!

===== Older versions of X.org =====

For older versions of Xorg or for Xfree86 ({{path|/etc/X11/XF86Config}}) try this:

Option "Emulate3Buttons" "true"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"

Now restart X and hold down button two and move the mouse for scrolling. To get a middle click, press buttons 1 and 3 simultaneously.

==Soft Transparent Mode==
If you wish to connect a special device to the external PS/2 port, you should consider using "Soft Transparent Mode" so that the TrackPoint controller does not interpret any commands sent to the external PS/2 port. You can enable soft transparent mode by typing the following in to a terminal:

:{{cmdroot|echo -n 1 > /sys/devices/platform/i8042/serio0/serio2/transparent}}

Disabling soft transparent mode is similar:

:{{cmdroot|echo -n 0 > /sys/devices/platform/i8042/serio0/serio2/transparent}}

==Modify trackpoint parameter permanently in trackpoint.h==
If you do not want to run a script to reconfigure the trackpoint
you can change the default settings in the trackpoint header file that is located in
/usr/src/<KERNEL_VERSION>/drivers/input/mouse/trackpoint.h.

First you must convert the values (decimal numbers) you normaly echo to /sys/[...] to hex:

'''echo -e 'obase=16;<DECIMAL_NUMBER>' | bc'''

Then simply replace the default hex values in trackpoint.h, run 'make && make modules_install' to recompile and install psmouse.ko (should be compiled as module)

Example patch (speed=100, sensitivity=190, press_to_select=1):

==Configure firefox for using trackpoint horizontal scrolling==
Vertical Scrolling seems to work out of the box in firefox if you followed the steps above.
Anyway, there is a problem when you doesnt scroll exactly vertical, because horizontal scrolling turns into
browser BACK/FORWARD commands.
You can avoid this by typing about:config + ENTER in the address bar of firefox.
You have to adjust the following options:

<pre>
mousewheel.horizscroll.withcontrolkey.action = 3;
mousewheel.horizscroll.withcontrolkey.numlines = 1;
mousewheel.horizscroll.withcontrolkey.sysnumlines = true;

mousewheel.horizscroll.withnokey.action = 0;
mousewheel.horizscroll.withnokey.numlines = 1;
mousewheel.horizscroll.withnokey.sysnumlines = true;

mousewheel.horizscroll.withshiftkey.action = 1;
mousewheel.horizscroll.withshiftkey.numlines = 1;
mousewheel.horizscroll.withshiftkey.sysnumlines = true;
</pre>

==Configure Opera for using trackpoint horizontal scrolling==
You'll experience the same annoying problem with the popular browser Opera. To fix this you need to edit the configfile <tt>/usr/share/opera/ini/standard_mouse.ini</tt> and comment the following lines out
<pre>
Button6 = Back
Button7 = Forward
</pre>
so they look something 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>

Option "Emulate3Buttons" "true"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"

Now restart X and hold down button two and move the mouse for scrolling. To get a middle click, press buttons 1 and 3 simultaneously.

==Soft Transparent Mode==
If you wish to connect a special device to the external PS/2 port, you should consider using "Soft Transparent Mode" so that the TrackPoint controller does not interpret any commands sent to the external PS/2 port. You can enable soft transparent mode by typing the following in to a terminal:

:{{cmdroot|echo -n 1 > /sys/devices/platform/i8042/serio0/serio2/transparent}}

Disabling soft transparent mode is similar:

:{{cmdroot|echo -n 0 > /sys/devices/platform/i8042/serio0/serio2/transparent}}

==Modify trackpoint parameter permanently in trackpoint.h==
If you do not want to run a script to reconfigure the trackpoint
you can change the default settings in the trackpoint header file that is located in
/usr/src/<KERNEL_VERSION>/drivers/input/mouse/trackpoint.h.

First you must convert the values (decimal numbers) you normaly echo to /sys/[...] to hex:

'''echo -e 'obase=16;<DECIMAL_NUMBER>' | bc'''

Then simply replace the default hex values in trackpoint.h, run 'make && make modules_install' to recompile and install psmouse.ko (should be compiled as module)

==Configure firefox for using trackpoint horizontal scrolling==
Vertical Scrolling seems to work out of the box in firefox if you followed the steps above.
Anyway, there is a problem when you doesnt scroll exactly vertical, because horizontal scrolling turns into
browser BACK/FORWARD commands.
You can avoid this by typing about:config + ENTER in the address bar of firefox.
You have to adjust the following options:

<pre>
mousewheel.horizscroll.withcontrolkey.action = 3;
mousewheel.horizscroll.withcontrolkey.numlines = 1;
mousewheel.horizscroll.withcontrolkey.sysnumlines = true;

mousewheel.horizscroll.withnokey.action = 0;
mousewheel.horizscroll.withnokey.numlines = 1;
mousewheel.horizscroll.withnokey.sysnumlines = true;

mousewheel.horizscroll.withshiftkey.action = 1;
mousewheel.horizscroll.withshiftkey.numlines = 1;
mousewheel.horizscroll.withshiftkey.sysnumlines = true;
</pre>

==Configure Opera for using trackpoint horizontal scrolling==
You'll experience the same annoying problem with the popular browser Opera. To fix this you need to edit the configfile <tt>/usr/share/opera/ini/standard_mouse.ini</tt> and comment the following lines out
<pre>
Button6 = Back
Button7 = Forward
</pre>
so they look something 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>

How to configure the TrackPoint

2006-06-28T07:56:05Z

Cryptom: /* EmulateWheelTimeout temporarily broken */

{| width="100%"
|style="vertical-align:top;padding-right:20px;width:10px;white-space:nowrap;" | __TOC__
|style="vertical-align:top" |The [[Patch to enable advanced trackpoint configuration|kernel trackpoint driver]] is controlled by echoing values to special files. Common configuration options are outlined below.
{{NOTE|
*Starting from 2.6.13 config files for this driver are located in <tt>/sys/devices/platform/i8042/serio0/serio2</tt>. (This document uses the new locations.)
*From 2.6.11 on, they are in <tt>/sys/devices/platform/i8042/serio0</tt>.
*Prior to kernel 2.6.11, these files were located in <tt>/proc/trackpoint</tt>.
*Prior to kernel 2.6.9, these files were not files at all, but were command-line options to the psmouse module. (Note this means you must compile psmouse as a module!) See http://stephen.evanchik.com/node/16.
}}
|}

==General Configuration==
The configuration options are reflected by the files you can find in {{path|/sys/devices/platform/i8042/serio0/serio2}}. See the [[Patch to enable advanced trackpoint configuration|TrackPoint driver page]] for a complete list.
Configuration is done by echoing the appropriate values into these special files.

==Most common Features==
The most common settings are '''Press to Select''', '''sensitivity''', '''speed''' and '''scrolling'''.

===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/serio0/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/serio0/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/serio0/serio2/speed}}
:{{cmdroot|echo -n 250 > /sys/devices/platform/i8042/serio0/serio2/sensitivity}}

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

===Scrolling===
====Using a kernel prior to 2.6.11====
The scrolling action is essentially the same as is used in the TrackPoint Windows drivers. To enable this feature, type the following in to a terminal (you may need to be root):

:{{cmdroot|echo -n 1 > /proc/trackpoint/scroll}}

Then press the middle button and push the stick up and down to scroll. Similarly, to disable scrolling:

:{{cmdroot|echo -n 0 > /proc/trackpoint/scroll}}

====Using the X server (kernel 2.6.11+)====
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.

The necessary functionality, known as "EmulateWheellTimeout" 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, which change axis orientation:

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

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.

===== EmulateWheelTimeout temporarily broken =====

Unfortunately, there was a regression so that EmulateWheelTimeout was broken in X.org 6.9.0, and fixed
on March 20th, 2006.
You can see the [https://bugs.freedesktop.org/show_bug.cgi?id=5071 primary bug report] here, and also reports on the [http://qa.mandriva.com/show_bug.cgi?id=21196 Mandriva] and [http://lists.debian.org/debian-x/2006/01/msg00249.html Debian] packages.

Unfortunately, this bug is still present in Ubuntu Dapper Drake's xserver-xorg-input-mouse package (version 1.0.3.1+cvs.20060109-0ubuntu2)!
Use the following procedure to make it work:

- insert/uncomment the deb-src lines in /etc/apt/sources.list
- change to a new/empty directory
- execute: apt-get update
- execute: apt-get source xserver-xorg-input-mice
(in order to get the source code)
- execute: aptitude install xserver-xorg-dev
(this package and the packages it depends on are needed in order to compile the source code,
use aptitude for easy removal later on)
- execute: cd xserver-xorg-input-mouse-1.0.3.1+cvs.20060109/
- execute: wget http://librarian.launchpad.net/2639933/xserver-xorg-input-mouse_1.0.3.1%2Bcvs.20060109-0ubuntu2.debdiff
(downloads the patch that fixes the bug)
- execute: patch -p1 < xserver-xorg-input-mouse_1.0.3.1%2Bcvs.20060109-0ubuntu2.debdiff
(applies the bug fix)
- execute: fakeroot dpkg-buildpackage
(rebuilds the package... watch out for errors and install other missing packages)
- execute: sudo dpkg -i ../xserver-xorg-input-mouse_1.0.3.1+cvs.20060109-0ubuntu2_i386.deb
(installs the rebuilt built package)
- optionally execute: aptitude remove xserver-xorg-dev
(removes the packages needed to rebuild the package)

Hope it works for you, it did work for me!

Talk:Patch to enable advanced trackpoint configuration

2005-05-18T15:46:20Z

Cryptom:

IMHO the driver should not emulate a mousewheel, this should be done by the Xserver.
e.g. (for Xfree86)
Section "InputDevice"
Identifier "TouchPoint"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mouse1"
Option "Protocol" "auto"
Option "Emulate3Buttons" "1"
Option "EmulateWheel" "on"
Option "EmulateWheelButton" "2"
Option "XAxisMapping" "6 7"
Option "YAxisMapping" "4 5"
EndSection
However, when I tried this I found the scrolling too jerky and missed the third mouse button.
--[[User:Onion|Onion]] 00:27, 5 Feb 2005 (CET)

----

I've used the trackpoint as mentioned above with the following additional section for an USB mouse:
Section "InputDevice"
Identifier "USB Mouse"
Driver "mouse"
Option "SendCoreEvents" "true"
Option "Device" "/dev/input/mouse1"
Option "Protocol" "ImPS/2"
Option "ZAxisMapping" "4 5"
EndSection

However, I've used /dev/input/mouse0 for the trackpoint and /dev/input/mouse1 for the USB mouse.

As of Kernel 2.6.10, the middle USB mouse button (used for pasting) doesn't work anymore (same config as for Kernel 2.6.9, execpt for the newly included ibm-acpi support).

Anyone one else with the same problem or with a solution?

[[User:Cryptom|CrypTom]] 10:29, 8 Mar 2005 (CET)

----

Any word on 2.6.11 support? I've seen the treads about this being included in the main tree but I guess it didn't make it. Any sign of a patch?

----

Elsewhere on the linked-to-blog ( http://stephen.evanchik.com/index.cgi/2005/01/index.html ), there is mention of a 2.6.11 patch. It's for 2.6.11-rc2, but should be worth a try. There're even newer patches here ( http://people.clarkson.edu/~evanchsa/software/kernel/patches/ ).

----

Thanks, this patch applies cleanly to 2.6.11:
http://people.clarkson.edu/~evanchsa/software/kernel/patches/trackpoint-2.6.11-rc3.patch-1
seems to work for me.

== scrolling with firefox ==

Firefox has an option to do smoothscrolling when you push down the third mouse button :)

== Middle Button Scrolling ==

On http://people.clarkson.edu/~evanchsa/ I read, that middle button scrolling is no longer supported. I couldn't find any additional information on this topic!? Anyone knows why support for mb scrolling is dropped?
