In my last post I talked about Clickpad support in the synaptics driver. Unfortunately, right around the same time a kernel bug surfaced that messed with the events from some clickpads (the Synaptics-branded ones, Apple and others were unaffected).
Affected was the 3.3.x series and obviously 3.4.
Thanks to +Benjamin Herrenschmidt, that bug was fixed and it is now available in a variety of kernels. The upstream commit is in Linus tree now, still making it into stable (not in 3.3.4 yet).
Fedora users can grab Fedora 17 or Fedora 16 kernels that carry this patch.
