Hi,

is there a way to turn on/off my touchpad?

I do not know which touchpad I have:

# cat /proc/bus/input/devices
I: Bus=0019 Vendor=0000 Product=0002 Version=0000
N: Name="Power Button (FF)"
P: Phys=ACPI_FPB/button/input0

I: Bus=0019 Vendor=0000 Product=0001 Version=0000

B: KEY=10000000000000 0

I: Bus=0011 Vendor=0001 Product=0001 Version=ab41

B: KEY=402000000 3802078f840d001 feffffdfffefffff fffffffffffffffe

I: Bus=0011 Vendor=0002 Product=0005 Version=0063
N: Name="ImPS/2 Logitech Wheel Mouse"
P: Phys=isa0060/serio2/input0
S: Sysfs=/class/input/input5
H: Handlers=mouse0 event5
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=103

I: Bus=0003 Vendor=046d Product=c404 Version=0110

S: Sysfs=/class/input/input6
H: Handlers=mouse1 event6
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=103

It works very well without any extra stuff.
My xorg.conf

Section "InputDevice"
Identifier "TouchPad"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "Auto"
Option "ZAxisMapping" "4 5"
EndSection

Is there a way to disable/enable the touchpad on the fly?

Hi,

I found http://gentoo-wiki.com/HARDWARE_Synaptics_Touchpad

So I am trying the solution described there, but I get this error:

$ syndock
pad.cpp:203 can't access shared memory area. SHMConfig disabled?
pad.cpp:114 cannot access driver, please install and configure it properly!

When I start the synaptic touch pad I got the error message that I have t set "UseShm" "true" in the touchpad section.

Section "InputDevice"
Driver "synaptics"
Identifier "TouchPad"
Option "Device" "/dev/input/mouse0"
Option "Protocol" "auto-dev"
Option "LeftEdge" "1700"
Option "RightEdge" "5300"
Option "TopEdge" "1700"
Option "BottomEdge" "4200"
Option "FingerLow" "25"
Option "FingerHigh" "30"
Option "MaxTapTime" "180"
Option "MaxTapMove" "220"
Option "VertScrollDelta" "100"
Option "MinSpeed" "0.09"
Option "MaxSpeed" "0.18"
Option "AccelFactor" "0.0015"
Option "SHMConfig" "on"
Option "UseShm" "true"
EndSection

What did I missed?

Edit: I found this in xorg.log:

Query no Synaptics: 6003C8
(EE) TouchPad no synaptics touchpad detected and no repeater device
(EE) TouchPad Unable to query/initialize Synaptics hardware.
(EE) PreInit failed for input device "TouchPad"
(II) UnloadModule: "synaptics"

But the touchpad is working ....

Instead of "UseShm" "true"

Option "SHMConfig" "on"
Option "UseShm" "true"
EndSection

try this:
Option "SHMConfig" "on"

P.S. If you use KDE, try ksynaptics to enable/disable the touchpad on the fly ( and for others cool features )

Hi delian,

I set both options, together and separately. Without shared memory there is no ksynaptic.

I found in xorg.log:

Query no Synaptics: 6003C8
(EE) TouchPad no synaptics touchpad detected and no repeater device
(EE) TouchPad Unable to query/initialize Synaptics hardware.
(EE) PreInit failed for input device "TouchPad"
(II) UnloadModule: "synaptics"

So my hardware is not supported... Is there no workaround?

I have some problem.. Did somebody solve it??
When I start "KSynaptics" I get the error:

Code: Select all

Shared Memory is not accessible.
Please add the option 'UseShm "true"' into the touch pad section of /etc/X11/xorg.conf.

But I have the "Option "UseShm" "true"" line in my TouchPad section..

Hi,

may be your touchpad isn't supported too. Look out in your x.org log.

hm.. I looked in /var/log/Xorg.0.log and saw smth like this:

Code: Select all

denis@localhost ~ $ cat /var/log/Xorg.0.log | grep -i synaptics
(II) LoadModule: "synaptics"
(WW) Warning, couldn't open module synaptics
(II) UnloadModule: "synaptics"
(EE) Failed to load module "synaptics" (module does not exist, 0)
(EE) No Input driver matching `synaptics'

I did "emerge synaptics" and it work's fine!!!!

You have to configure it in your xorg.conf. Google around for the correct parameters. Must be something like this.

Code: Select all

Section "InputDevice"
        Identifier  "TouchPad"
        Driver    "synaptics"
...

I did "emerge synaptics" and it work's fine!!!!

That means not that that driver is useful for you, just that it was compiled and installed.

Not all touchpads are synaptics (although I don't own any that aren't). I have some notes on turning a (synaptics) touchpad into a scrolling device, which might be useful.
