Synaptics touchpad problem

OK, SO I installed the synaptics package from the DVD, and copied /usr/share/hal/fdi/policy/10osvendor/11-x11-synaptics.fdi to /etc/hal/fdi/policy/ as per other forum posts I found.

I then edited /etc/hal/fdi/policy/11-x11-synaptics.fdi to contain only:

<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
    <match key="info.capabilities" contains="input.touchpad">
        <merge key="input.x11_driver" type="string">synaptics</merge>
        <!-- Arbitrary options can be passed to the driver using
             the input.x11_options property since xorg-server-1.5. -->
        <merge key="input.x11_options.SHMConfig" type="string">true</merge>
        <merge key="input.x11_options.MaxTapMove" type="string">2000</merge>
        <merge key="input.x11_options.VertEdgeScroll" type="string">true</merge>

I then restarted HAL and X after doing so, however there was no change.

I attempted this after succusfully changing my keyboard layout, so was somewhat familiar with the routine.

From what I can see, I should have tapping and vertical scrolling enabled, but it simply does not work.

I would also like to know how to decrease the sensitivity/speed, as I understand everything is handled by HAL and this would be the place to do it.

Any help appreciated

Grr God I hate HAL. You can control how the synaptics touch pad behaves right in the Xorg.conf file. I control side scrolling and even how fast it responds to finger movements in my xorg.conf file. Below is part of my xorg that deals with the driver.

Section "InputDevice"
	Identifier  "Synaptics Touchpad"
	Driver      "synaptics"
	Option	    "Protocol" "auto"
	Option	    "Device" "/dev/input/mice"
        Option      "VertEdgeScroll" "true"
        Option      "TapButton1"    "1" # 1 finger - left 
        Option      "MinSpeed"      "0.10"  # speed factor for low pointer mov
        Option      "MaxSpeed"      "0.40" # max speed factor for fast pointer 
        Option      "AccelFactor"   "0.0030" #Acceleration factor for normal

I don't have an xorg file because I have not needed it until now.

Is it not possible to set it up with HAL and HAVE to use xorg.conf?

I'm no HAL guru but I did fix the tap click on my Synaptics touch pad with:

merge key="input.x11_options.TapButton1" type="string">1</merge>
I'm confident if you search around you'll be able to find all the HAL policy tweaks you need.

post # 6 of

worked for me

the default file is a fully commented out block.

maybe your typing in the commented out section?

i have nothing in my xorg.conf for mouse at all, I'm using his settings, so I have vertical, horiz scroll, and tap to click.

This is all fixed.

I added the following lines to my 11-x11-synaptics.fdi file. I'm surprised I missed them out somehow :\

<merge key="input.x11_options.TapButton1" type="string">1</merge>
<merge key="input.x11_options.MinSpeed" type="string">0.1</merge>
<merge key="input.x11_options.MaxSpeed" type="string">0.4</merge>
<merge key="input.x11_options.AccelFactor" type="string">0.002</merge>
