+Background: I'm planning to switch from a CentOS 6 workstation to one running Fedora 17.  Some things are different.  I have questions.

+Unfortunately, I'm suffering from this problem:

+http://major.io/2013/08/24/get-a-rock-solid-linux-touchpad-configuration-for-the-lenovo-x1-carbon/ makes me wonder if this has something to do with my settings at /usr/share/X11/xorg.conf.d/50-synaptics.conf or /usr/share/X11/xorg.conf.d/50-wacom.conf

+The former says, "Some devices have the buttons as part of the lower edge of the touchpad.  Pressing a button moves the cursor, causing cursor jumps and erroneous clicks." I'm definitely suffering from similar problems. Before making any changes, here are my current settings:

+Strangely, it almost seems related to being plugged into power... if I touch and hold my finger on the touchpad while plugged into power, the cursor oscillates. When I unplug from power, the cursor is more stable. As of this writing I'm on Fedora 20. I don't see this behavior when I reboot into Windows.
