Hans de Goede posted the following comment on Launchpad bug #1323346:
Hi, Fixing this is non trivial, supporting these new touchpads likely needs a signicant amount of work (for details see https://bugzilla.redhat.com/show_bug.cgi?id=1110011 ). In the mean time, I can provide a workaround which should make the touchpad work in ps/2 mouse emulation mode (so no 2 finger scrolling, etc.), and stop it from interfering with an external mouse. Sounds good? Try booting with "psmouse.proto=bare" on the kernel cmdline. See: https://wiki.ubuntu.com/Kernel/KernelBootParameters for how to add a parameter to the kernel commandline. Regards, Hans
To test this workaround, do the following:
$ sudoedit /etc/default/grub
Change GRUB_CMDLINE_LINUX_DEFAULT to add psmouse.proto=bare at the end, and save your modifications.
$ sudo update-grub
And finally reboot.
