Hmmm... interesting!

looking at the MATE section (since I run the MATE desktop), I do
the two dconf-editor settings listed there.

then I do (skipping a step or two in what I show here):

xinput list-props "SynPS/2 Synaptics TouchPad" | grep Capabilities
	Synaptics Capabilities (324):	1, 1, 1, 0, 0, 1, 1

which reports :

>From left to right, this shows:

    1: device has a physical left button
    1: device does not have a physical middle button
    1: device has a physical right button
    0: device does not support two-finger detection
    0: device does not support three-finger detection
    1: device can configure vertical resolution
    1: device can configure horizontal resolution 

where the two zeroes indicate 2 and 3-finger operations do not seem
to be supported.

Since The Main Thing I would like to have that I cannot get working are
two-finger horiz/vert scrolling, this seems to say that the device does
not recognize (and never will) that feature. Even though the Mate 
touchpad settings show they are enabled, as does synclient.

My thought on this is: :-( :-( :-( :-( :-( :-(


I guess that since the laptop was free, I shouldn't complain.

Thanks for the pointer!
