Michael -Hanselmann added support for the October 2005 models. - -Usage: ------- - -In order to use the touchpad in the basic mode, compile the driver and load -the module. A new input device will be detected and you will be able to read -the mouse data from /dev/input/mice (using gpm, or X11). - -In X11, you can configure the touchpad to use the synaptics X11 driver, which -will give additional functionalities, like acceleration, scrolling, 2 finger -tap for middle button mouse emulation, 3 finger tap for right button mouse -emulation, etc. In order to do this, make sure you're using a recent version of -the synaptics driver (tested with 0.14.2, available from [2]), and configure a -new input device in your X11 configuration file (take a look below for an -example). For additional configuration, see the synaptics driver documentation. - - Section "InputDevice" - Identifier "Synaptics Touchpad" - Driver "synaptics" - Option "SendCoreEvents" "true" - Option "Device" "/dev/input/mice" - Option "Protocol" "auto-dev" - Option "LeftEdge" "0" - Option "RightEdge" "850" - Option "TopEdge" "0" - Option "BottomEdge" "645" - Option "MinSpeed" "0.4" - Option "MaxSpeed" "1" - Option "AccelFactor" "0.02" - Option "FingerLow" "0" - Option "FingerHigh" "30" - Option "MaxTapMove" "20" - Option "MaxTapTime" "100" - Option "HorizScrollDelta" "0" - Option "VertScrollDelta" "30" - Option "SHMConfig" "on" - EndSection - - Section "ServerLayout" - ... - InputDevice "Mouse" - InputDevice "Synaptics Touchpad" - ... - EndSection - -Fuzz problems: --------------- - -The touchpad sensors are very sensitive to heat, and will generate a lot of -noise when the temperature changes. This is especially true when you power-on -the laptop for the first time. - -The appletouch driver tries to handle this noise and auto adapt itself, but it -is not perfect. If finger movements are not recognized anymore, try reloading -the driver. - -You can activate debugging using the 'debug' module parameter. A value of 0 -deactivates any debugging, 1 activates tracing of invalid samples, 2 activates -full tracing (each sample is being traced): - modprobe appletouch debug=1 - or - echo "1" > /sys/module/appletouch/parameters/debug - -Links: ------- - -[1]: http://johannes.sipsolutions.net/PowerBook/touchpad/ -[2]: http://web.archive.org/web/*/http://web.telia.com/~u89404340/touchpad/index.html |
