How the hell do you disable multi-touch?

[user376]

Seriously... it's annoying because I'm using a dell mini 10v netbook and the click is built into the trackpad. I can't drag things because the mouse starts moving crazy from the multi-touch.

How do I disable it?

Have you looked at System/Preferences/Mouse to see if there are any touchpad settings there?

BTW: it is frowned upon when you bump a thread so soon. Give it at least a day.

Yes I checked there, and there aren't any settings having to do with multi-touch. I installed Synaptics TouchPad and there are no multi-touch settings in there either.

I'm changing the options with "synclient OPTION=VALUE", but it has no effect on the touchpad. Why is this??

During step 2 did you find that you had an xorg or HAL configuration?

If it is not currently configured through eiither then try to start shmconfig like this:

gksudo gedit /etc/hal/fdi/policy/shmconfig.fdiThe file should be empty so copy and past this into it:

<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" string="synaptics">
<merge key="input.x11_options.SHMConfig" type="string">on</merge>
</match>
</device>
<device>
<match key="info.linux.driver" string="psmouse">
<merge key="input.x11_options.SHMConfig" type="string">True</merge>
</match>
</device>
</deviceinfo> Restart the computer and then try synclient.

If synclient still does not work then go to sectio 4c of the guide and try to udev configuration like so:

ACTION!="add|change", GOTO="touchpad_end"
KERNEL!="event*", GOTO="touchpad_end"
ENV{ID_INPUT_TOUCHPAD}!="1", GOTO="touchpad_end"
ENV{x11_options.TapButton2}="0"
ENV{x11_options.TapButton3}="0"
LABEL="touchpad_end"

Make sure you're restarting X and/or your computer after you edit any configuration files, including xorg.conf.

My xorg.conf file looks like:

My synaptics.fdi file (/usr/share/hal/fdi/policy/20thirdparty/11-x11-synaptics.fdi) looks like this:

I tried to change the BottomEdge value to 4000, which is having no effect.

I changed shmconfig.fdi to what you said, and it also has had no effect.

I've restarted my comp, and nothing changes.

I have a dell mini 10v so the clicks are built into the trackpad. What I'm trying to do is reduce the BottomEdge trackpad area so the cursor doesn't move when I click, and I'm trying to disable multi-touch so I can click and drag without the cursor flying around wild.

[pi/roman]

To disable multitouch use

synclient tapbutton2=0
synclient tapbutton3=0If it works then place it in your HAL configuration.

Try this to adjust your touchpad area:

xinput set-int-prop '"SynPS/2 Synaptics TouchPad"' 'Synaptics Area' 32 0 0 0 4000If this doesn't work then you can remove it by:

xinput delete-prop '"SynPS/2 Synaptics TouchPad"' 'Synaptics Area'

Something else that may be causing you problems is rtcornerbutton and rbcornerbutton which cause you to copy and paste and such things when you hit the corner of your touchpad.
Changing those to 0 will fix that.

The udev command opened up a blank document, so I pasted the code into it and saved. It had to effect on the multi-touch. Should I restart my comp?

[pi/roman]

Yes, a restart should be necessary.

Then see if your settings are correct.

If they are not, then try this:

xinput set-int-prop '"SynPS/2 Synaptics TouchPad"' 'Synaptics Tap Action' 8 0 0 0 0 1 0 0

[user376]

If they are not, then try this:

Restarted my computer, multi-touch is still enabled.


I entered that command and it didn't do anything.

[pi/roman]

Just trying to work the problem, I can see that the settings are being adjusted properly through hal because it successfully changed the bottomedge to 4000. So if the settings are being changed the problem must be that we are missing a setting that is registering multiple touches.

The only other setting I see that could have an effect is emulatetwofingerminz which is already set very high. If you don't using tapping you could set tapbutton1 to 0 which should disable tapping completely. That would also be a good test to ensure that the synaptics driver is working properly as once all 3 tapbuttons are disabled you should not be able to tap to click with any number of fingers. You should expirement with other values and just remember what they were set at because it must be one of them we haven't tried yet.

BottomEdge = 4000The synclient command works because you entered this

Just copy/pasted what you said. The tapping for clicking was disabled, but the multi-touch is still enabled. Also, the entire trackpad is still sensitive so I don't think the BottomEdge has changed anything.

[pi/roman]

It is probably one of those settings that is still causing multi-touch but I'm not sure what it would be.
For disabling the bottom of the touchpad you could try

synclient areabottomedge=4000which is the command that is supposed to be used as in the synaptics manual:

Option "AreaBottomEdge" "integer"
Ignore movements, scrolling and tapping which take place below this edge. The option is disabled by default and can be enabled by setting the AreaBottomEdge option to any integer value other than zero. Property: "Synaptics Area"but it will probably return an error since it is not your your synclient list.

[pi/roman]

Here are some more you could try



<merge key="input.x11_options."ClickFinger2" type="string">0</merge>
<merge key="input.x11_options."ClickFinger3" type="string">0</merge>disables clicking with multiple fingers


<merge key="input.x11_options."Touchpadoff" type="string">2</merge>disables tapping and scrolling but doesn't seem to effect scrolling
