Comment 11 for bug 1793584

Okay, I haven't yet lost the trackpad completely, but twice now tap to
click has stopped working. The first time I rebooted to make sure it had
actually been working under the test kernel (I was pretty sure it had, but
wanted to confirm). The second time I removed and reloaded the i2c_hid
module; tap to touch returned, but there now a visible jitter in moving the
cursor.
