GSynaptics is a tool for configuring Synaptics touchpads. It uses synclient as a backend, so your xorg.conf has to list Option "SHMConfig" "true" in the Synaptics section. There are a bunch of options available, like vertical and horizontal scroll, circular scrolling (iPod-style), tapping, etc. I just packaged up GSynaptics 0.9.14 for Hardy. It can be found in my PPA (see right side) if you'd like to install it. The reasons you may want to install this one instead of what's in the default repos are:
- Sensitivity fixed
- Minimum and maximum speed settings added
- Acceleration settings added
I just learned to make packages yesterday when I was doing Twitux, so I figured I ought to do this before I forget how.
EDIT: JDong says to include the warning from Synclient's manpage.
