Dear The-Wise,
I can't find a solution to my Elantech issue and believe me I have looked. I am running 12.04 on an Asus 1011px.

I can't seem to actually control the sensitivity of the pad from accidental triggering. If I have "tap to click" enabled, it will mis-fire even when the sensitivity is set to minimum in "preferences/mouse and touchpad".

I've fiddled about with command line codes but none of them seem to atually be operating on the touchpad. I can't work out where it's getting its instructions from, i.e. what is the actual driver for the pad.
Here's what the OS is telling me.

Code:
~$ xinput list
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ ETPS/2 Elantech Touchpad                	id=13	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Video Bus                               	id=7	[slave  keyboard (3)]
    ↳ Power Button                            	id=8	[slave  keyboard (3)]
    ↳ Sleep Button                            	id=9	[slave  keyboard (3)]
    ↳ USB2.0 UVC VGA WebCam                   	id=10	[slave  keyboard (3)]
    ↳ Eee PC WMI hotkeys                      	id=11	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=12	[slave  keyboard (3)]

I thought to alter a few properties, such as
Code:
$ xinput --set-prop --type=int "ETPS/2 Elantech Touchpad" "Synaptics Palm Detectection" 1
Notably, I tried to alter the area of the touchpad to desensitize the area near the top by the space bar that causes the triggering, but whatever I set the area to, it made no difference to the area of response of the pad.
e.g.
Code:
$ xinput --set-prop --type=int "ETPS/2 Elantech Touchpad" "Synaptics Edges" 27 168 47 485
I have had a look for an Xorg.conf file in /etc/x11 and I don't appear to have one. Is that usual for newer versions of Ubuntu?

So, can anyone help me to find out what is controlling my touchpad?
Many thanks, Wise Ones,
Scot
