Comment 66 for bug 146946

Well, since set_touchpad_enabled() and other functions that were
introduced by 08_extra_touchpad_options.patch also didn't contain any
#ifdef HAVE_XINPUT sections, I thought it would be a bit overkill.

It all depends on whether the extra_touchpad_options code will be sent
upstream later. If that's the case, it should probably be cleaned up a
little more anyway. Any idea if it's going to be sent upstream?

As to the issue other people in this bug report have, when I apply my
own fix, gnome-settings-daemon does startup now, but sooner or later I
also get the dreaded "The program 'gnome-settings-daemon' received an X
Window System error" message. :)

So back to stack-tracing again...
