interesting dicussion. I own another HP laptop, the 4320s, with a
ClickPad.  Situation is pretty bad on that one. Patch from Yan Li
enables the right and middle click (thank you). But never solves the
jump issue, nor does the Add-new-option-JumpyCursorThreshold-v5.patch

If the synaptics driver in the kernel is supposed to recognize it as
such, it does not in this case: Synaptics Touchpad, model: 1, fw: 7.4,
id: 0x1e0b1, caps: 0xd04731/0xe40000/0x5a0400

I've been looking forward to Takashi's fixes, but barely none are in
the kernel yet. I had a chance to use SuSE and the pad was OK, jumpy
though, also the LED to disable it in the top left corner was working.

I tried to tweak just about every setting, from palm detection,
reducing the area etc. Nothing helped. If I move the thumb in the
position for a click and a finger is already on the touchpad these
mostly horizontal jumps occur. If I swipe the thumb into position it
moves across the screen in a huge jump. It doesn't seem to be
connected to horizontal scrolling in any way, I also disabled it.

> I can also confirm that setting EmulateTwoFingerMinW=5

The jump while clicking still occures as ever. With any value. :(
