    Re: Macbook touchpad cursor moving "in steps"

    OK, one more try!

    The outputs are the following:

    uname -r
    Code:
    2.6.24-19-generic
    lsusb
    Code:

    I added the line "blacklist usbhid" to the end of the file /etc/modprobe.d/blacklist, but I'm not sure what to change on /etc/modules. The file does not include "appletouch" or "usbhid". Should I add both to the end of the file?

    Thanks once again,
    Tiago

    Yes, just make sure that usbhid is on a line after appletouch.

    I tried to do that, but unfortunately the result was the same. Thanks for trying to help anyway.

    Do you think the following patch might help?

    Reading the patch, it seems it has already been applied some time ago, unfortunately.

    Re: Macbook touchpad cursor moving "in steps"

    I've been trying different options in Xorg.conf and I guess I found a configuration that works fairly well to me. I'll post it in case someone would like to try it:

    Code:
    Section "InputDevice"
    	# Basic settings
    	Identifier	"Synaptics Touchpad"
    	Driver		"synaptics"
    	Option		"SendCoreEvents"	"true"
    	Option		"Device"		"/dev/psaux"
    	Option		"Protocol"		"auto-dev"
    	Option		"SHMConfig"		"true"
    	# Trackpad edges
    	Option		"LeftEdge"		"10"
    	Option		"RightEdge"		"1200"
    	Option		"TopEdge"		"10"
    	Option		"BottomEdge"		"370"
    	# Tap buttons
    	Option		"TapButton1"		"1"
    	Option		"TapButton2"		"3"
    	Option		"TapButton3"		"2"
    	# Corner taps (disabled)
    	Option		"RTCornerButton"	"0"
    	Option		"RBCornerButton"	"0"
    	Option		"LTCornerButton"	"0"
    	Option		"LBCornerButton"	"0"
    	# Two-finger scroll
    	Option		"VertTwoFingerScroll"	"on"
    	Option		"HorizTwoFingerScroll"	"on"
    	Option		"VertScrollDelta"	"20"
    	Option		"HorizScrollDelta"	"50"
    	# Edge scroll (disabled)
    	Option		"HorizEdgeScroll"	"off"
    	Option		"VertEdgeScroll"	"off"
    	# Locked drag (disabled)
    	Option		"LockedDrags"		"off"
    	# Finger pressure
    	Option		"FingerLow"		"10"
    	Option		"FingerHigh"		"20"
    	# Pointer speed and acceleration
    	Option		"MinSpeed"		"0.15"
    	Option		"MaxSpeed"		"1.00"
    	Option		"AccelFactor"		"0.15"
    	# Single tap
    	Option		"MaxTapTime"		"180"
    	Option		"MaxTapMove"		"220"
    	Option		"SingleTapTimeout"	"100"
    	# Double tap
    	Option		"MaxDoubleTapTime"	"220"
    EndSection
    The trackpad behavior should be similar to the one in Mac OS X. At least I'm happy with the results now.

    I have this problem as well. Overall touchpad movement is not that smooth.

    Re: Macbook touchpad cursor moving "in steps"

    Sorry to bring up an old thread, but as I'm having the exact same problem...
    Think I've got a Macbook Pro 3,1 and the cursor is moving just as described in the first post. It's annoying because I have to be with a mouse to use, for example, the selection tools in GIMP.
    It moves sort of like it wants to go in a straight vertical/horizontal line as much as possible. It doesn't like going diagonal slowly.
    So if anyone ever solved this problem, I'd like to know.
    Thanks

    You may have conflicting settings... Make sure you don't have the touch pad configured in xorg.conf and hal fdi

    Actually, my xorg.conf has nothing related to Synaptics or the touchpad. All my touchpad settings are in /etc/hal/fdi/policy/appletouch.fdi.
