I have the same problem in linux mint 17.2, with my Asus Zenbook ux305FA, and tried, inspired by Fabio's comment #59, to manually patch synaptics.c (see http://pastebin.com/raw.php?i=BC3fgErn ) from the package xserver-xorg-input-synaptics_1.7.4 in the mint repository.
More precisely, I pasted in the last chunk of +'ed lines in https://bugs.freedesktop.org/attachment.cgi?id=100632 as a replacement of line 3003: inside_active_area = is_inside_active_area(priv, hw->x, hw->y); in synaptics.c file. This compiled into a package that I could install, but the bug persisted. Thanks for any help or advice on how to fix this bug! -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1026046 Title: Missing support for thumb resting on bottom of clickpad Status in Xserver Xorg Input Synaptics: Unknown Status in xserver-xorg-input-synaptics package in Ubuntu: In Progress Status in xserver-xorg-input-synaptics source package in Precise: Confirmed Status in xserver-xorg-input-synaptics package in Debian: New 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.
