Comment 5 for bug 516329

The Synaptics touchpad in question is a new model, known as a "clickpad". It actually has a single physical button underneath the bottom edge of the touchpad, and the driver is supposed to determine whether the click is "left" or "right" by looking at finger position on the pad.

It's important to realize that the "workaround" that people are using basically makes the pad appear as a PS/2 mouse to the kernel. This means no edge or two-finger scrolling, and the touchpad will stay active when typing. Not optimal.

There are two patches in development. One is to the Synaptics X driver; the other is to the kernel. BOTH of the patches will be necessary to get the proper behaviour. Read the mailing list thread posted by Paul for details.

Both the Ubuntu X team and the Kernel team will need to collaborate on a fix. Getting late for Lucid now.
