Title:
Wrong handling of forcepad edges
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have experienced incorrect behaviour of the driver when forcepad
very edges are touched (HP Elitebook 1040 G1). With Tap-and-drag
gesture disabled and even tapping disabled (although this does not
change anything) when one finger touches the touchpad and another taps
the very edge of the touchpad (any side), the system behaves as if
there was a click and hold action as long as the finger is on the
touchpad. This seems to be linked to the driver reporting a left click
when the second finger touches the veery edge of the touchpad, see
output from evtest below.
How to replicate: disable tapping. On the desktop, put one finger on
the touchpad, then lightly tap the very 1mm of the edge. Move the
first finger down and right and notice an area being selected. This
should only happen when the finger is pressed (like for a click)
against the touchpad and held so during the move.
Attached are outputs from synclient and xinput.
I believe it is a bug in a kernel driver.
From system logs:
