mouse pointer shaking/bouncing when using laptop trackpad

I need to somehow adjust the pointing device driver to get more precision out of the trackpad on my HP dv8000. The pointer would move around a few pixels if I hold my finger still on the trackpad. The pointer stays still if I try the same on Windows XP.

Input device sections of xorg.conf:

Code:

Section "InputDevice"

Identifier  "Mouse0"

Driver      "mouse"

Option      "Protocol" "auto"

Option      "Device" "/dev/input/mice"

Option      "ZAxisMapping" "4 5"

EndSection



Section "InputDevice"

 Identifier    "Synaptics Touchpad"

 Driver        "synaptics"

 Option        "SendCoreEvents"    "true"

 Option        "Device"            "/dev/psaux"

 Option        "Protocol"          "auto-dev"

 Option        "SHMconfig"        "true"

 Option        "HorizScrollDelta"  "0"

 Option        "VertEdgeScroll"  "1"

 Option        "TapButton1"  "1"

EndSection

There must be a way to filter out that input noise or whatever.
This makes it really difficult to select text, press titlebar buttons, use scrollbars or any other task that requires precision.
Once again, the trackpad works fine on Windows, there is nothing mechanically wrong with the trackpad (or the user).
Thanks in advance.

My Debian OS provides a GUI which allows you to change driver parameters on-the-fly.

For KDE it seems to be ksynaptics, for GNOME there is a gsynaptics package. Hope that tool can help you a little. My only one laptop which has also a Synaptics touch pad is badly broken and doesn't start up, also the gurantee has expired. :(

Another idea of mine would be to connect an external USB mouse to your laptop. Just in case. :)

Anyway I was using my trackpad with Windows XP during class today, and it works fine. After class I booted into Linux, the pointer is bouncing around, wiggling around like there some sort of noise.

Just in case, I of course have and used a USB mouse but I can't always use it on the go, considering I have only two knees.

THERE IS A PROBLEM WITH LINUX TRACKPAD DRIVER, DON'T LET THIS THREAD DIE!!!

BUMP.

Still having a problem, the pointer bounces around whenever I touch the trackpad while using Linux, fine with Windows.
Driver issue.

BUMP.

It's very difficult to work while the mouse pointer jumps around. I can't believe I am the only one with a trackpad driver/configuration problem ever.
