And somewhere in the web I saw a resitive touchpad witch could regocnize up to five fingers and different pressure...

But not five independent positions? My old laptop with resistive touchpad could determine the count of fingers I was pressing with (Scrolling, rightclick). Gestures like zooming weren't possible.

So this is limited by the firmware in the touchpad itself?

Apparently, yes. But you can't get more information than position and proximity/pressure anyway.

I found a video where a touchpanel can recognize more fingers:

I think they're subdividing the screen into sections, each treated seperately.
With resistive Touchpads you can't measure proximity and position without contact,
so the nspire does indeed have not a resistive one.

Can someone make a tutorial about how to set up linux on a CX? Im a bit of a noob, and I can't load the kernel for some reason, don't know why

My idea behind the multi-touch question was that we could make a virtual screen in the X server that is bigger than the actual screen, and we could scroll in this virtual screen with a special gesture or when we click the pad and move or something like that. So we don't have to use mini scroll bars on the sides.

? We can't help you if you don't provide enough information.
What did you do and which step fails?

I go kernel /linux/zImage.tns and it tells me that the kernel does not exist or is empty

kernel /linux/zImage.tns and it tells me that the kernel does not exist or is empty

kernel linux/zimage.tns

4. Download my patch (for X, directfb...) "wget http://dl.dropbox.com/u/105478372/fbdev.patch" and apply it "git apply fbdev.patch"

Can someone fix this link pls? I'm trying to build my own kernel and it looks like it's down
