Comment 24 for bug 296610

I have the same problem on 2 E4300, and 1 M4400. I see the problem with both 9.04 and 9.10.

On 9.04 I have reduced the problem by disabling the touchpad, but as this option has been removed in 9.10 I have instead forced the PS2 protocol to Internet Explorer mode by creating the following file:

/etc/modprobe.d/psmouse.modprobe

which contains:

options psmouse proto=exps

I dont have scrolling on the touchpad, but for me thats fine
