@Grabiele Finally I've solved my problem by installing the 3.16 kernel form here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16-utopic/
Now everything is working as intended, so I will work with that kernel until Ubuntu 14.10 is released. Thank you for the support. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1305522 Title: Backport Synaptics HID touchpad driver for 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1305522/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
