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
