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 -- ALPS DualPoint Touchpad flaky performance https://bugs.launchpad.net/bugs/296610 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
