I have a Dell Inspiron 6000 with an AlpsPS/2 ALPS GlidePoint touchpad.

      Code:
cat /proc/bus/input/devices

I: Bus=0011 Vendor=0002 Product=0008 Version=7321
N: Name="AlpsPS/2 ALPS GlidePoint"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input7
U: Uniq=
H: Handlers=mouse1 event7
B: PROP=0
B: EV=b
B: KEY=420 0 70000 0 0 0 0 0 0 0 0
B: ABS=1000003


It's working fine, and thanks to kde-config-touchpad horizontal scrolling is also working.

Thing is though, while typing if I bump the touch pad with my palm, the cursor goes all over the place.

Thus typing can be a deadset pain. It has been bothering me for a while and finally I've decided to do something about it, if possible.

I've done a good deal of reading on the topic, and found that it is possible to set up 'palm detection'.

The following output from synclient

      Code:
synclient -l | grep Palm
    PalmDetect              = 0
    PalmMinWidth            = 10
    PalmMinZ                = 99


cut and paste from man synaptic

      Code:
 
Option "PalmDetect" "boolean"
              If palm detection should be enabled.  Note that this also requires hardware/firmware support from the touchpad. Property: "Synaptics Palm Detection"
             
       Option "PalmMinWidth" "integer"
              Minimum finger width at which touch is considered a palm. Property: "Synaptics Palm Dimensions"
             
       Option "PalmMinZ" "integer"
              Minimum finger pressure at which touch is considered a palm. Property: "Synaptics Palm Dimensions"


So it's definitely possible, but, does the AlpsPS/2 ALPS GlidePoint support palm detection?

None of the articles / wikis that I have read, nor the Alps company website provide specifications or confirm 'palm detection' capability.

There is no point in proceeding further if it does not.

Secondly, if so, has anyone configured it successfully?

Cheers.

tpconfig output this :
      Quote:

~$ tpconfig
Could not open PS/2 Port [/dev/psaux].


and systemsettings recognize mouse but no touchpad

anything new for this ? i have to use syndaemon because of the lack of configuring possibilities so to correct the erratic moves you experienced
