[Bug 1026046] Re: Missing support for thumb resting on bottom of clickpad

 

If you're using 14.04.2 (utopic enablement stack), I have solved on
xserver-xorg-input-synaptics-lts-utopic:

### Build the deb
apt-get build-dep xserver-xorg-input-synaptics-lts-utopic
apt-get source xserver-xorg-input-synaptics-lts-utopic
cd xserver-xorg-input-synaptics-lts-utopic
wget -q -O - https://bugs.freedesktop.org/attachment.cgi?id=100632 | patch -p1 
# if it asks for a missing file, write: "src/synaptics.c" (without quotes) and press enter to confirm
dpkg-buildpackage -us -uc -nc
cd .. #here there should be your debs ready to be installed 


### Configure trackpad
sudo mkdir -p /etc/X11/xorg.conf.d/
sudo wget -q -O /etc/X11/xorg.conf.d/10-synaptics.conf http://pastebin.com/raw.php?i=drJKRmW8
sudo gedit /etc/X11/xorg.conf.d/10-synaptics.conf
# now set your button area and save
# reboot and login again

Note: this guide is based on a previous guide, but uses the patch that
you find here https://bugs.freedesktop.org/attachment.cgi?id=100632

  Missing support for thumb resting on bottom of clickpad

Bug description:
  When using the trackpad on the MacBook Pro In Mac OS X it is possible to have the thumb resting (ready to click) on the bottom part of the touchpad while moving the mouse pointer around with your index or middle finger. 
  Likewise it is also possible to use two finger scrolling with the index and middle finger on the upper part on the track pad while resting the thumb on the lower part of the trackpad.

  This behaviour is not currently supported with the synaptics driver in
  12.04. It wil register a two finger scroll when the thumb is resting
  in the bottom part and index finger moves around in the upper part.

  I have tried playing aroud with the setting AreaBottomEdge that
  disables all motion on the bottom part of the touchpad. Unfortunately
  when this setting is enabled it still detects a finger in the area, so
  it wil register a two finger scroll like before.
