Turn off Synaptics absolute mode [SOLVED]

Hello all,

I've recently noticed that my ALPS Glidepoint doesn't work as I like any more. It is in some sort of "absolute" mode which I hate. In this mode, the touch pad is mapped directly to the screen, so if you touch the upper right corner of the touch pad, the cursor will jump to the upper right part of the screen. This makes the touch pad impossible to use. If you select a control and then lift your finger and then want to move to a nearby control, you have to place your finger exactly at the last point you touched the pad. Otherwise, the cursor will jump to a new point and messes up navigation.

Now, unfortunately I'm not sure when this started, as usually I use a USB mouse and only occasionally use the touch pad. Here is the configuration of my device:

Section "ServerLayout"
        Identifier     "Xorg Configured"
        Screen         "aticonfig-Screen[0]"
        InputDevice    "Keyboard0" "CoreKeyboard"
        InputDevice    "Synaptics Touchpad" "CorePointer"
        InputDevice    "Logitech V220" "SendCoreEvents"
EndSection

...

Section "InputDevice"
        Identifier  "Synaptics Touchpad"
        Driver      "synaptics"
        Option      "Device" "/dev/psaux"
#       Option      "Device" "/dev/input/event7"
        Option      "Protocol" "auto-dev"
        Option      "SHMConfig" "on"
        Option      "Emulate3Buttons" "on"
        Option      "LeftEdge" "120"
        Option      "RightEdge" "830"
        Option      "TopEdge" "120"
        Option      "BottomEdge" "650"
        Option      "FingerLow" "14"
        Option      "FingerHigh" "15"
        Option      "MaxTapTime" "180"
        Option      "MaxTapMove" "110"
        Option      "EmulateMidButtonTime" "75"
        Option      "VertScrollDelta" "40"
        Option      "HorizScrollDelta" "40"
        Option      "MinSpeed" "0.6"
        Option      "MaxSpeed" "1.2"
        Option      "AccelFactor" "0.03"
        Option      "EdgeMotionMinSpeed" "200"
        Option      "EdgeMotionMaxSpeed" "200"
        Option      "UpDownScrolling" "1"
        Option      "CircularScrolling" "1"
        Option      "CircScrollDelta" "0.1"
        Option      "CircScrollTrigger" "2"
EndSection

Note that when this worked, I was using the "Device /dev/input/event7" line, but when it stopped working I tried to do what the synaptics package said (use psaux) when it upgraded, but it still does not work.

If anyone has any idea on how to get back the normal, non-absolute mode I would greatly appreciate it, as I cannot use the touch pad as it is.

Thanks and regards.

This is all I've got for my touchpad and it works perfect. Check the wiki, too, if you haven't already. And make sure you have synaptics loaded in the module section.

Good Luck!

Re: Turn off Synaptics absolute mode [SOLVED]

Well, what do you know. I did a system upgrade, which loaded a new kernel and now it works! I knew it wasn't the config, since that config has worked since I got this machine a couple of years ago. Anyway, it is working now, so no worries.
