@Javier Vela Did you try 3.17-rc1? If so, take a look at this: https://bugzilla.kernel.org/show_bug.cgi?id=82601
@piotr If the jumps happen when you use two fingers, maybe this (http://lists.freedesktop.org/archives/xorg-devel/2014-June/042790.html) could help. If this is the case, then it's not a kernel bug. That patch could also help if the bug you are experiencing is the same as the one you linked which seems to be a kernel bug. Note that the patch I linked is not a kernel patch, so it's not something that can be included in the backported kernel. ** Bug watch added: Linux Kernel Bug Tracker #82601 http://bugzilla.kernel.org/show_bug.cgi?id=82601 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1305522 Title: Backport Synaptics HID touchpad driver for 14.04 Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Trusty: Fix Released Bug description: Synaptics just upstreamed a new set of HID touchpad driver: http://git.kernel.org/cgit/linux/kernel/git/jikos/hid.git/commit/?h=for-3.16/rmi4&id=9fb6bf02e3ad04c20edb8e46536ce3eeda32c736 It's better we can have it in 14.04 .
