Title: How to disable the touchpad?
Post by: bengt_t on May 09, 2012, 05:40:36 AM

With my Laptop I use an external, USB-connected, mouse and wish to disable the integrated touchpad.

Using OpenSuse with Xfce, in an identical Laptop, I can disable the touchpad by adding "synclient TouchpadOff=1" in the .xinitrc file. This does however not bite in Tiny Core Linux.

Where and how shall the touchpad be disabled in Tiny Core Linux?

if you search this forum on alps or synaptic or touchpad, there's several posts on the subject

Thanks for your hint!

After some reading I realized that, in my case, it helped to modify the first line of my .xsession file from
"Xvesa ... -mouse /dev/input/mice,5 ... "
to
"Xvesa ... -mouse /dev/input/mouse0,5 ... ".

mouse0 is my external mouse and mouse1 the touchpad.

Hi bengt_t
Personally, I can't stand touch pads, so I always disable them in the BIOS.

I definitely agree, touchpad is a pain I a try to disable it in BIOS if I can.

However, it seems to me that disabling in BIOS is not always possible. As in HP ProBook 4525s, which I am presently struggling with...

i try synaptic but it seem do not work.
I have eeepc t101mt, core 4.4 and xorg 7.4. OPS, I HAVE XORG 7.5!, this changes everything, how do I disable the touchpad?


in order:
1) I killled
2) I generated X -configure and I placed in /etc/X11
3) inside I wrote this section found in a blog (http://embraceubuntu.com/2006/03/24/disable-synaptics-touchpad/):
Section "InputDevice"
        Identifier      "Synaptics Touchpad"
        Driver          "synaptics"
        Option          "SendCoreEvents"        "true"
        Option          "Device"                "/dev/psaux"
        Option          "Protocol"              "auto-dev"
        Option          "HorizScrollDelta"      "0"
        Option          "SHMConfig"             "on"
EndSection

4)tc @ box: ~ $ synclient -l
Could not find synaptics properties. No synaptics driver loaded?
tc @ box: ~ $

My friend says it is a kernel problem, but I do not understand a tube

If it helps, this disabled the touchpad, but allowed the pointing stick to work with Xorg-7.5

Code: [Select]

Section "ServerLayout"
Identifier "X.org Configured"
Screen      0  "Screen0" 0 0
InputDevice "DualPoint Stick" "CorePointer"
InputDevice "Alps Touchpad"  "SendCoreEvents"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
Identifier  "DualPoint Stick"
Driver      "evdev"
Option     "Device" "/dev/input/event5"
EndSection

Section "InputDevice"
Identifier "Alps Touchpad"
Driver  "synaptics"
Option "Device"  "/dev/input/event6"
Option "SHMConfig" "true"
Option "GuestMouseOff" "false"
Option "TouchpadOff" "1"
EndSection

uh, solved a problem if it has another, if we now attack the mouse does not work anymore, I think it's a matter of loaded drivers.
I tried to edit the xorg config creating a hybrid between the auto-configuration and the modified version I wrote in previous message.

Code: [Select]

Section "InputDevice"
Identifier  "Mouse0"
Driver      "synaptics"
*** Driver      "mouse"
*** Option     "Protocol" "auto"
Option     "Device" "/dev/input/mice"
*** Option     "ZAxisMapping" "4 5 6 7"
Option "SHMConfig" "true"
Option "GuestMouseOff" "false"
Option "TouchpadOff" "0"

Entries preceded by asterisks are those that I have added, In this way the mouse works but not the "synaptic" touchpad (so that I can not turn off).
I feel I should add another section exclusively for mouse input devices and does not alter the section of the touchpad

I think you'll need a separate section for a mouse - it would not use the "synaptics" driver for example.

New section with the same device? (Option       "Device" "/dev/input/mice") ???
