Hi,

I have a DELL XPS 12 convertible. After applying the last kernel updates
from proposed, with the last kernel the problem with the synaptic module
persists. The touchscreen works perfectly but the synaptics touchpad
gestures do not work. With the Acelan's custom kernel everything is
working but if I try the upstream kernel , it stops working. If I
blacklist the i2c_hid module, the synaptics tocuhpad works perfectly,
but in the moment I load it again, the gestures stops working. In fact,
if I don't blacklist the i2c_hid module, the synaptic dirver does not
load, seeing this:

# synclient -l
Couldn't find synaptics properties. No synaptics driver loaded?

I've checked errors in xorg or dmesg, but nothing found, plus without
the i2c_hid moudle is working. I've also purged and reinstalled the xorg
synaptics package, but problem persists. AT the beginning I was working
with the bentiss patch, but is not working with the last kernel sources,
and the Acelan's custom kernel would got outdated at some point.
