Elantech 'ETPS/2' Clickpad on 'Asus Zenbook ux31a': unable to move cursor while thumb is resting on the left button

[Ivan]

It is a usual behaviour when you rest your finger on left button area(not clicking it) and move cursor with your index finger.
Unfortunately it doesn't work.

evtest and xev reports contain attempt to move cursor while resting finger on the left button area.

Sorry for my english :)

Running an Asus K55a here with the same Elan clickpad. For me, right click and some other things where broken until I put the following into the (new) xorg.conf file. Now everthing works except this issue.

I think what is needed is to set the property "AreaBottomEdge" to some value so that the lower portion of the touchpad surface is disabled with regard to mouse pointer movement.

I tried my suggestion and while I figured out that 1800 is the correct value, this bug remains.

Status changed to 'Confirmed' because the bug affects multiple users.
