Description Simon 2014-12-28 10:35:14 UTC 
With my Acer Travelmate B115-M running Ubuntu 14.04 x64, when I click the bottom left or right area on my clickpad to either primary or secondary click, the cursor jumps to another place on the screen far away from its initial location and executes the click at that location.

The problem applies generally to clickpads in any laptop.

This workaround helped me solve the problem: 

Execute the following at a terminal:
synclient RTCornerButton=0
synclient RBCornerButton=0
synclient LTCornerButton=0
synclient LBCornerButton=0
synclient AreaBottomEdge=3900


Also filed it as a bug on launchpad:

what's your synaptics version and does the problem go away if you update to 1.7.6 or later?
