I just installed gentoo, running X and kde and everything.... I have a laptop and use the synaptics driver. Whenever I place my finger anywhere on the touchpad, the mouse will move to the top left. Why is that?

I had some erratic mouse problems with the touchpad a while back. Here's the touchpad part of my /etc/X11/xorg.conf file

Code:

Section "InputDevice"
    Identifier   "Touchpad"
    Driver   "synaptics"
    Option   "Device"   "/dev/input/event1"
    Option      "Protocol"      "auto-dev"
    Option      "LeftEdge"      "1900"
    Option      "RightEdge"     "5400"
    Option      "TopEdge"       "1800"
    Option      "BottomEdge"    "3900"
    Option      "FingerLow"     "25"
    Option      "FingerHigh"    "30"
# setting taps and horizscrolldelta to 0 to rid myself of the erratic touch pad behavior
    Option      "MaxTapTime"    "180"
    Option      "MaxTapMove"    "220"
#    Option      "MaxTapTime"    "0"
#    Option      "MaxTapMove"    "0"
    Option      "HorizScrollDelta" "0"
    Option      "VertScrollDelta" "100"
    Option      "MinSpeed"      "0.02"
    Option      "MaxSpeed"      "0.18"
    Option      "AccelFactor"   "0.0010"
EndSection


I seem to remember that (with the help of my comments to myself in the file) that it was the HorizScrollDelta being set to 0 that helped.

Hope this helps.

Actually the mouse works fine (fine but slow) until I install ksynaptics. After that, the mouse still moves to the top left. I tried your configuration cerebus_k and it still does it.... Any ideas?
