Touchpad does not work if finger moves too slow

[mark4]

I can not see any touchpad device under lsusb or lshw or lspci so i have to assume my touchpad is on i2c or something. it does work but if i am trying to just move the pointer . <--- that far.. so I can drag a window border for example the pointer simply does not move. It only moves if my finger moves above a certain speed threshold which makes it almost impossible to control the pointer.

It helps when asking for help for problems like this, is the vendor and model of laptop were given.

And have you looked at the bios to see if there are any settings for the touchpad?

We had many problems in the past where an i2c connected touchpad didnt work because of missing kernel options. But the fact that a touchpad works - just not normally - is a new problem. I would immediately ask the following questions:

1 Does it work if you boot our GentooLIVE CD?
2 If no: Does it work when you boot (the latest) UbuntuLIVE CD?

1+2 no -> This touchpad has problem under linux
1+2 yes -> 3. Did you manually configure your kernel yourself?

3 yes -> We need the output of “dmesg" after you booted our GentooLiveCD + the "dmesg" after you booted your Gentoo system + your current kernel .config
