I have a similar issue with my click pad (Dell XPS 15). The issue is well described in the upstream project there: https://bugs.freedesktop.org/show_bug.cgi?id=66532
The patch suggested by one maintainer (Kit Westneat) fixes the issue as far as I am concerned, and I can finally keep my fingers on the buttons without blocking the mouse movement done with the other finger. I attach the (modified) patch to add to the package to solve the issue. To test: apt-get source xserver-xorg-input-synaptics cp path/to/fix_multitouch_outside_area.patch xserver-xorg-input-synaptics-1.8.2/debian/patches/ echo fix_multitouch_outside_area.patch >> xserver-xorg-input-synaptics-1.8.2/debian/patches/series cd xserver-xorg-input-synaptics-1.8.2 dpkg-buildpackage cd .. sudo dpkg -i xserver-xorg-input-synaptics_1.8.2-1ubuntu3_amd64.deb reboot and tell synaptics to ignore the bottom clickpad area: xinput set-prop 12 "Synaptics Area" 0, 0, 0, 800 Result: I can now keep my left thumb on the bottom left button while moving the cursor with the right hand. ** Bug watch added: freedesktop.org Bugzilla #66532 https://bugs.freedesktop.org/show_bug.cgi?id=66532 ** Patch added: "fix_multitouch_outside_area.patch" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1257153/+attachment/4813085/+files/fix_multitouch_outside_area.patch -- 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/1257153 Title: Option "AreaBottomEdge" ignores other areas when active Status in xserver-xorg-input-synaptics package in Ubuntu: Confirmed Bug description: Just got a new laptop with one of the infamous "ClickPads," been playing around for a couple hours to get the thing to work decently. After enabling Option "AreaBottomEdge" "82%", I finally got it to ignore movement in the "button" areas, but if I put my finger down in that 18% area first, the top 82% of the touchpad ignores any movement from a second finger. This makes it difficult to perform a click and drag operation. Inversely, if I touch in the top 82% first, then click on the 18% bottom button area, then I still get cursor movement from the top area. It's a workaround I suppose, but not ideal. Still debating about sending this laptop back and buying something from 2011 to meet my "netbook" requirements Using xserver-xorg-input-synaptics 1.7.1-0ubuntu1 on saucy.
