The kernel is not reporting to the userspace the width of the fingers with new touchpads, even if the hardware is capable of that. The reason is that pressure and width are not independent, so knowing one of them is enough (at least according to what's written here: https://lkml.org/lkml/2011/8/15/73).
The problem here is that the userspace driver was not updated to meet this decision and hence the patch I posted here above is required. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1245328 Title: Synaptics kernel driver does not report finger width information, breaking usermode driver's palm detection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1245328/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
