The touchpad on my laptop appears to be no longer functioning. I typically use an external keyboard and mouse, so I didn't notice the problem until I tried to use the touchpad. I'm running Gentoo Linux.
Even after I toggled the on/off switch several times, the touchpad still wouldn't work.
I saw something in the logs about cannot read byte from synaptics device. I will post the full logs when I am in front of my machine.
