    Question Synaptics touchpad driver issue

    Hi,
    From last system upgrade my synaptics touchpad driver's stoppet to work properly. I tryed to reinstall them but nothing changed.
    I read ALL old discussions in this and in other forums, but nothing worked to me.
    This is the error:
    Code:
    synclient
    Couldn't find synaptics properties. No synaptics driver loaded?
    here some log and settings infos:

    Re: Synaptics touchpad driver issue

    Are you using a logitech device? Somewhere and for some unknown reason the Logitech support for touchpads was removed from the Kernel. I can only get the synaptic driver to load again if I install Kernel 3.19, then all my logitech functionality is returned. However, this breaks Fglrx so I am back on 3.16 until I get figure out how to patch 3.16. Since the new alpha version of 1504 doesn't have Kernel 3.19 it feels like it could be a long wait to get everything back to normal.
