--- Comment #33 from Peter Hutterer <peter.hutterer at who-t.net> ---
Note you'll also need to run udevadm hwdb --update afterwards, and check for
the various udev properties we talked about. Without that, it won't pick things
up.

You can check with sudo ./builddir/libinput-debug-events (i.e. in the git tree)
and see if palm detection roughly works there. That's a separate context and
won't interfere with the xserver libinput context. Check for the dwt pairing
message. If it  all works there, the rest is just a matter of making sure the
.so files are in the right place. The X server itself has no effect here, this
is all libinput-internal.

Of course, you need to make sure you're not using the synaptics driver (xinput
list-props <device name> will tell you which driver is used).
