Thinkpad X200 Trackpoint

Os dejo un problema que me he encontrado con la ultima actualización, se ve que desde xorg estan haciendo ultimamente muchas modificaciones y las configuraciones por hal o por udev pueden ser ignoradas, así que os dejo un poco la problematica, las formas posibles de configurar el trackpoint y finalmente la solución al problema en debian squeeze.

Hi guys!
I’m really confused with this topic… before an update my trackpoint scrolling worked well, I simply had to add a rule on udev:

[/etc/hal/fdi/policy/mouse-wheel.fdi]
< 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>

I supposed that in update maybe that will be deprecated and simply delete this entry (backed up to an other directory) and rebooted, then I saw that it still don’t worked, so then I started to search.

http://www.thinkwiki.org/wiki/How_to_co … TrackPoint

So then I configured trackpoint through hal:

[/etc/hal/fdi/policy/mouse-wheel.fdi]
< 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>

rebooted (with udev and without udev rules) and still not worked.

so then I tried xinput, what it shows, but simply xinput don’t see trackpoint (it is working, but the most important, the scrolling is not working)

#  xinput set-prop '"IBM Enhanced (101/102-key, PS/2 mouse support)"'  "Evdev Wheel Emulation Axes" 6 7 4 5
unable to find device "IBM  Enhanced (101/102-key, PS/2 mouse support)"
# xinput set-prop  '"TPPS/2 IBM TrackPoint"' "Evdev Wheel Emulation Axes" 6 7 4 5
unable  to find device "TPPS/2 IBM TrackPoint"
# xinput set-prop '"PS/2  Generic Mouse"' "Evdev Wheel Emulation Axes" 6 7 4 5
unable to find  device "PS/2 Generic Mouse"

in each change I tried first to reboot x, and then reboot the computer with no chance.

so then I thought this was caused for a changing on xorg or hal and goes to seach for trackpoint configs on kernel, I compiled by hand 2.6.33.2 kernel, with also no chance.

gpointed also don’t shows the trackpoint as it shows in this image:
http://www.thinkwiki.org/wiki/How_to_co … sing_Gnome

I try to configure mouse emulation (it only appears the one with a mouse), but each time I reboot the config resets, and rebooting x, also don’t works.

I don’t know where to see, it is a little bit stressing use a thinkpad x200s without trackpoint scrolling.

Does anyone had the same problem? how do you solved?

Thanks you much

Minutos mas tarde….

well, finally I could make work it.

I didn’t know that new versions of xorg also takes the info of xorg.conf file, unless it don’t exist.

1. I create a new file called /etc/X11/xorg.conf with this content:

Section "InputClass"
Identifier      "Trackpoint  Wheel Emulation"
MatchProduct    "TPPS/2 IBM  TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad /  TrackPoint"
MatchDevicePath "/dev/input/event*"
Option          "EmulateWheel"          "true"
Option           "EmulateWheelButton"    "2"
Option           "Emulate3Buttons"       "false"
Option           "XAxisMapping"          "6 7"
Option          "YAxisMapping"           "4 5"
EndSection

2. restart x

and now it is working.

Nota: no es lo mismo InputDevice y InputClass, así que si tenemos un viejo fichero de xorg quizás no funcionará.

En debian wheezy (8)

# vi /usr/share/X11/xorg.conf.d/20-thinkpad.conf
Section "InputClass"
     Identifier "Trackpoint Wheel Emulation"
     MatchProduct       "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint|ThinkPad USB Keyboard with TrackPoint|ThinkPad Compact USB Keyboard with TrackPoint|USB Trackpoint pointing device"
     MatchDevicePath    "/dev/input/event*"
     Option             "EmulateWheel"          "true"
     Option             "EmulateWheelButton"    "2"
     Option             "Emulate3Buttons"       "false"
     Option             "XAxisMapping"          "6 7"
     Option             "YAxisMapping"          "4 5"
