[gentoo-user] disable syanptics pad

[gentoo-user] disable syanptics pad

[James]

Hello,

One of my gentoo users only uses and external mouse
and hates the synaptics pad.

I cannot get rid of the input being active from the
synaptics pad.


make.conf has this entry:
INPUT_DEVICES="keyboard mouse evdev"
VIDEO_CARDS="fbdev fglrx  vesa"


In xorg.conf I have it explicitly disabled:

#       InputDevice     "Synaptics" "AlwaysCore"


Here is what is installed:
ati-drivers 8.32.5 
kde-3.5.9
xorg-x11-7.4


It has this video chip:
Radeon XPRESS 200M 5955 (PCIE)



Any ideas how to disable the synaptics pad?

James

I think you need to set corepointer=0 in the FDI file or something
similar to that. Or if you're using xorg.conf point it to a specific
mouse instead of /dev/mice or whatever the catch-all mouse device is.
May be able to get rid of it "even more" with udev rules or something
to just make it go away. Sorry I don't have specific examples, I'm on
a windows machine right now.

I'm sure your information is good. But, I need specifics....

This is from my /etc/hal/fdi/policy/10-xinput-configuration.fdi:
=================================================
<!-- touchpad --> 
<device>   
   <match key="info.capabilities" contains="input.touchpad"> 
   <match key="info.product" contains="SynPS/2">
        <merge key="input.x11_driver" type="string">synaptics</merge> 
        <merge key="input.x11_options.SHMConfig" type="string">true</merge>
        <merge key="input.x11_options.VertEdgeScroll" 
type="string">true</merge>
        <merge key="input.x11_options.HorizEdgeScroll" 
type="string">true</merge>
        <merge key="input.x11_options.TapButton1" type="string">1</merge>
        <merge key="input.x11_options.ClickButton1" type="string">1</merge>
   </match> 
   </match> 
</device>
=================================================

Try modifying the above with something like:
<merge key="input.x11_options.corepointer" type="string">0</merge>

You may want to try my fdi as is first.  It may just work without problems in 
your setup and the touchpad will become useful again.

Note: This is on a system which does not use xorg.conf anymore.  I am not sure 
how things get parsed by xorg when both an fdi and a xorg.conf are present.

HTH.

thanks mick,

Sorry for the delayed response. I only get sporadic access to this 
laptop. I'm going to research how to remove xorg.conf from a system
completely. Once I do this, I'll give your suggestion a whirl and 
post to a new thread.

thanks very much,


James

Have you looked in the Bios?
Somewhere around there should be an option to turn the touchpad
completely off

After booting, I'm pretty sure Linux just ignores the bios
on most systems.....?

I'm not entirely sure that's a proper way to disable the synaptics pad,
as you don't seem to have removed xorg's ability to load the driver. I'd
suggest just #'ing out the whole InputDevice section relating to the
synaptics pad, and running emerge -C synaptics or emerge -C
xf86-input-synaptics, depending on which driver you're using. That
should completely remove your ability to use the synaptic touch pad.

Hmmmm,


Nothing with the word "synaptics"  (or either of the packages you mentioned)
is installed.


I do have a left over, bloated xorg file, so I'll first just delete
the line with the (#) symbol, but, I thought that was the way to
deactivate entries. Looking in xorg.conf.examples did not reveal
any sort of useful infor


Maybe somebody could post a minimal xorg.conf, or a url to some examples?

One additional bit of information. The synaptics pad, when touched, makes
the mouse(cursor) go crazy in a radom-noise-movement sort of pattern. 
When I stop touching the synaptics pad and use the external usb mouse, 
cursor  movement becomes normal as expected.


ideas?

Sounds like, since you don't have a synaptics driver installed, the
synaptics device is being handled like a regular mouse via the evdev driver,
and the evdev driver doesn't properly handle the data coming from the
touchpad, hence the erratic pointer movement.

For disabling, I'm not sure, as I don't have access to a system w/ synaptics
on it (until I get home, but that's about 8 hours away yet...), but, after
emerging the xf86-input-synaptics driver, and looking at the man page (man
synaptics), I see the

Option "TouchpadOff" "integer"

option - if you set this to "1", then the touchpad is disabled, so I would
add in a section for the device in your xorg.conf file, something like:

       Section "InputDevice"
         Identifier "touchpad"
         Driver "synaptics"
         Option "Device"   "/dev/input/<whatever-it-is - you can find out by
doing "cat /proc/bus/input/devices" and looking at the "Handlers" line>"
         Option "TouchpadOff" "1"
       EndSection

HTH-

Sorry for the delay, I only get access to this
laptop, on a sporadic basis. This did not work for me.
