Enabling the synaptics features on an iBook Clamshell

JoeyAdams · 02-21-2008, 10:21 PM

I'm working on the assumption that the iBook Clamshell has a synaptics-driven touchpad like the other iBooks, but I can't get it to be recognized in this fashion (it just uses a generic mode, which works well for basic mouse tracking). I can tell the vertical and horizontal scroll features are present in the device (but I can't use them) because dragging my finger on the right or bottom side will make the cursor go straight up or down, while dragging my finger on the left or top side will make it follow a curvy path.

My xorg.conf looks like this:

Code:

...
Section "Module"
        Load    "i2c"
        Load    "bitmap"
        Load    "ddc"

        Load    "extmod"
        Load    "freetype"
        Load    "glx"
        Load    "int10"
        Load    "vbe"
        Load    "synaptics"
EndSection
...

        Option          "Emulate3Buttons"       "true"
EndSection

Section "InputDevice"
        Identifier      "Synaptics Touchpad"
        Driver          "synaptics"
        Option          "SendCoreEvents"        "true"
        Option          "Device"                "/dev/input/mice"
        Option          "Protocol"              "auto-dev"
        Option          "HorizScrollDelta"      "0"
        Option          "SHMConfig"             "on"
        Option          "SHConfig"              "on"
        Option          "SHMconfig"             "on"
EndSection
...some wacom stuff...
...display stuff...
Section "ServerLayout"
        Identifier      "Default Layout"
        Screen          "Default Screen"
        InputDevice     "Generic Keyboard"
        #InputDevice    "Configured Mouse"
        #InputDevice     "stylus"       "SendCoreEvents"
        #InputDevice     "cursor"       "SendCoreEvents"
        #InputDevice     "eraser"       "SendCoreEvents"
        InputDevice     "Synaptics Touchpad"
EndSection

Section "DRI"
        Mode    0666
EndSection

Section "Extensions"
    Option         "Composite" "Enable"
EndSection

and `grep -i synaptics /var/log/Xorg.0.log' returns:

Code:

(**) |-->Input Device "Synaptics Touchpad"

I do have the evdev and psmouse modules loaded.

Despite all of this, `synclient -l' still responds "Can't access shared memory area. SHMConfig disabled?" (seemingly because the synaptics driver couldn't find the device). A full reboot didn't seem to help, either.

Are there any other things I could try, or does the iBook Clamshell simply not have that kind of trackpad?
