    Touchpad configuration tab disappeared

    I have an Acer Aspire E431 and Mint 14 Mate. I always have to re-enable the touchpad after each boot. Until this morning, I had to do ctrl fn f7 to enable it, but when I booted this morning, I discovered that the key combination had mysteriously changed to just fn f7. Also all my touchpad configuration options that I had configured had disappeared, and the touchpad configuration tab under control center/assisstive technologies/mouse was no longer there. Apparently this is the result of an update within the last week (Mar 20 -27) (for lack of any other cause). Does anyone know how to restore the configuration options tab to the Control Center? When I first installed Mint I remember that I had to do something to get the touchpad configuration options to show, but I don't remember what it was. I Tried reinstalling xserver-xorg-input-synaptics to no avail. Is there some other package I should install/reinstall or...? gpointing-device-settings is installed. I noticed that there is no xorg.conf file present under /etc/x11 as what I have read seems to indicate there should be. Something else I noticed is that the touchpad is currently being recognized as "PS/2 Synaptics TouchPad" but several months ago when I was dealing with another touchpad issue, it was recognized as "synPS/2 Synaptics TouchPad". I tried running synclient -l but there is no output from this at all. I tried installing the Synaptiks pacjage, but it says "Touchpad not found". I have read bug reports that suggest that the problem might be the result of a bad kernel update? Here is some information from various terminal commands:
