Synaptics and number of fingers

I have a Lenovo Thinkpad T500 and the touchpad works right using synaptics... except for multiple finger detection. From the wiki I can see that ALPS touchpads are not able to detect the number of fingers on the touchpad. How can I know if I have one of these touchpads?

Using synclient, when I touch with two fingers, only one is detected, albeit quite a wide one wink If it wouldn't be possible to detect the multifinger touch, could I use this "extra width" to emulate a middle mouse click?

Re: Synaptics and number of fingers

You'll find out that with:

cat /proc/bus/input/devices

Good luck!

I: Bus=0011 Vendor=0002 Product=0007 Version=01b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio1/input0
S: Sysfs=/class/input/input8
U: Uniq=
H: Handlers=mouse1 event8 
B: EV=b
B: KEY=6420 70000 0 0 0 0
B: ABS=11000003

Hmm, so it should support multi-touch, shouldn't it?

BTW. I have seen that I also have a "Macintosh mouse button emulation". Any idea what that is?

davvll:  Ive got the same thing on my Toshiba Satellite e105-s1402. Not sure what the Macintosh mouse button thing is. Might be for mice with only one button so ctrl+clicking is a right click. not sure though.
