Topic: Synaptics touchpad

http://linux.die.net/man/5/synaptics lists the variables for the synclient.
I'm new to using a laptop, and the touchpad is driving me crazy.  It scrolls on the right, and has tap touch.  I'm trying to get it to act more sane.  Mostly I use an external mouse.  When I type, if my hand goes too close (!) then the screen scrolls, or I end up on another screen workspace.

So far, I've disabled using the scrollwheel to switch spaces (somewhere in Xfce4 config), and tried enabling palm detect (synclient PalmDetect=1)

I still can't type!  The cursor has bumped around the screen 5 times and into other applications a few times just while typing this message.p

Is there like a notification area app that I can use to toggle on/off this stupid thing?  I use it some times, and don't want it permanently disabled.

My settings are:
Parameter settings:
    LeftEdge                = 1752

Re: Synaptics touchpad

I've had mixed success with touchfreeze in the past - http://packages.debian.org/testing/utils/touchfreeze

Re: Synaptics touchpad

From its description, it sounds like syndaemon.

syndaemon -d -K
Disables the touchpad for 2 seconds after each key press, except for modifier keys (ctl, alt) and modifier+key presses.

Re: Synaptics touchpad

I also found this at http://wiki.archlinux.org/index.php/Tou … _detection

Disable touchpad upon external mouse detection

In assistance to udev, it is possible to automatically disable the touchpad if an external mouse has been plugged in. To achieve this, add the following udev rule to /etc/udev/rules.d/01-touchpad.rules:

ACTION=="add", SUBSYSTEM=="input", ENV{ID_CLASS}="mouse", RUN+="/usr/bin/synclient TouchpadOff=1"
ACTION=="remove", SUBSYSTEM=="input", ENV{ID_CLASS}="mouse", RUN+="/usr/bin/synclient TouchpadOff=0"

SHMConfig must be enabled (see the Configuration section for details)

My system doesn't have that .rules file, maybe I'll try it.

Re: Synaptics touchpad

Hey, 73ChargerFan, did you ever get it fixed?  The reason I ask, and in the event you didn't know, is that gpointing-device-settings 1.5.1-2 is in the repository and has a feature that turns the touch pad off.  Perhaps you'd like to look at it.  wink

Re: Synaptics touchpad

A little snippet from my autostart.sh


# Detect and configure touchpad. See 'man synclient' for more info.
# FIXME: there is probably a better way of doing this!?
if egrep -iq 'touchpad' /proc/bus/input/devices; then
    synclient VertEdgeScroll=1 &
    synclient TapButton1=1 &
    synclient TouchpadOff=1 &
fi

You can use it of cause via alt+F2 or in a terminal, if you type the command followed by an &

synclient TouchpadOff=1   ... disables the touchpad and ...
synclient TouchpadOff=0   ... enables the touchpad

I personaly like to have the touchpad disabled. #! is good like it is for keyboard junkys wink

Have fun,

Karl

Re: Synaptics touchpad

Hi at all,
I am having a little problem, with my Touchpad.
When I start my system, horizontal scrolling, do not work.
Then I start "gpointing-device settings" and enable the feature and everything works fine.
After a new start, it dont work anymore, but the feature is still on..
As I start gpointing again and only klick anywhere in the window, it is working again, till a new start.
What's wrong?
Hope you understand my english.:-)

Re: Synaptics touchpad

I had the same experience as DocHiFi above using statler 32 on a Dell Inspiron 6400. The pad worked fine on a fresh install, but after updates and a reboot, scrolling and tap click were disabled.

Hi,
you don't have the same Problem, like me, because my problem is also happend after fresh install and tap click and vertical scrolling  works every time.

Re: Synaptics touchpad

What about putting a menu item in the openbox menu that disables och enables the touchpad via     synclient TouchpadOff = 0?
The easy way is to have two, one that says enable and one that says disable. Super key + space brings up the openbox menu, and just navigate with arrows.

Harder way is to have the menu item call a script that determines if the touchpad is on/off and then enable/disable it. Conky could be used to display touchpad on or off. I guess that this can be read from synclients config file, where that now is...

Hi GuruX
Maybe this is good for cchhrriiss121212
But not for me, I don't wan't to switch it on or off, because it work's fine, only horizontal scrolling don't work after a new start.
It look's like gpointing settings are not stored or overidden at startup.

EDIT:
Hi, I solve the problem for me, with this Thread:http://crunchbanglinux.org/forums/topi … uto-start/
I'm only put the following line in my "autostart.sh"

#Switch Horizontral Scrolling on
(sleep 2s && synclient HorizEdgeScroll=1)&

Now every time I start, horizontal scrolling is active and works fine.
Hope anyone can need it.
