I have the elantech touchpad on my zepto znote 3215W. Kernel 2.6.31-17-generic
the bug I reported in was assigned but is no longer so i don't know what is going to happen about it.

It was completely unusable and could not be configured. It is still not working fully.
I can now disable tapping but it seems there are at least 2 problems:
1/
There seems to be some interaction between psmouse and the keyboard - with psmouse loaded then there seems to be a huge amount of key bounce as I type so that it repeats many times like iiiiiiiiiiiiiiiiiiiiiiiiiiiii for one or more keys during typing a word. This is so in a terminal window, with gedit or openoffice writer and so on.
If I rmmod psmouse ( I am using a usb mouse and only load psmouse when testing ) the bounce goes away

2/
If I try to move the mouse pointer from the bottom to the top of the screen or vice versa then I have to stroke the touchpad several times - which is normal i know. Problem is that sometimes I might stroke it once from bottom to top, the pointer moves about 1/3 to 1/2 way up, then I put my finger at the bottom to stroke it again and the pointer jumps back down to the bottom of the screen as soon as my finger touches the pad. This sometimes means I have to stroke it as many as 10 or even 12 times before it gets where I want.
Then it might work normally for several minutes before it starts messing about again.
Not sure exactly what the issue is but I have tried other live distros such as mandriva and Suse and the problem is the same. I do wonder if it is a fault with my touchpad but it has been like this from day one when I was running Ubuntu 8.04. ( I bought the machine with no O/S )
