FC4 Mouse issues w/ ALPS touchpad



What I did was to install  synaptics-0.14.0-2.i386.rpm (which includes
Alps support).
Then you need to add some lines to /etc/X11/xorg.conf to enable Alps
mouse support

The relevant lines that I have are:
Section "ServerLayout"
        Identifier     "single head configuration"
        Screen      0  "Screen0" 0 0
        InputDevice    "alps" "AlwaysCore"
#       InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
        Identifier  "alps"
        Driver      "synaptics"
        Option      "Device" "/dev/input/mice"
        Option      "Protocol" "auto-dev"
        Option      "LeftEdge" "120"
        Option      "RightEdge" "900"
        Option      "TopEdge" "120"
        Option      "BottomEdge" "680"
        Option      "FingerLow" "14"
        Option      "FingerHigh" "15"
        Option      "MaxTapTime" "180"
        Option      "MaxTapMove" "110"
        Option      "EmulateMidButtonTime" "75"
        Option      "VertScrollDelta" "20"
        Option      "HorizScrollDelta" "20"
        Option      "MinSpeed" "0.3"
        Option      "MaxSpeed" "0.75"
        Option      "AccelFactor" "0.015"
        Option      "EdgeMotionMinSpeed" "200"
        Option      "UpDownScrolling" "1"
        Option      "TouchpadOff" "0"
        Option      "SHMConfig" "on"
        Option      "CircScrollTrigger" "2"
        Option      "CircularScrolling" "0"
EndSection

If all this doesn't work it, try googling around for more complete
documentation. The FC4 kernel already includes the needed ALPs patches
so it should just be a matter of fiddling around with your X
configuration. You can use synclient to try to determine the best
parameters for your hardware.
