I can confirm this bug on my Dell Inspiron 510m with AlpsPS/2 ALPS GlidePoint touchpad. Downgrading to version 0.99.3-2ubuntu4 fixes the problem. However, the downgrade triggers bug #327428: some pixels can not be reached anymore.
By the way, doing 'rmmod psmouse; modprobe psmouse proto=imps' makes the touchpad even smoother, but of course removes scrolling and such. -- touchpad mouse stutters/stops on slow movement https://bugs.launchpad.net/bugs/379517 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
