I sometimes get the jitter too but I've yet to find a reliable way to reproduce it.
I also get low speed jitter where the packets reported to the interrupt handler don't have new x and y coords but the pressure is changing. This results in jerkiness at very low speed which I can reliably reproduce. This looks to some extent like h/w (or rather touchpad firmware) but i need to work my way down the input stack to convince myself of that yet. I'm trying to work through touchpad related stuff this week as i have some spare time. I'll update if i get anywhere. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1722478 Title: Two-finger scrolling and click-and-drag no longer works after resuming from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1722478/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
