My Dell Latitude D600 has an Alps Synaptics Touchpad and Dual Point Stick. The Dual Point stick causes the mouse pointer to become unresponsive whenever I use the keyboard or accidentally hit the stick.

I've tried many different configurations in xorg.conf but can't disable the DualPoint without disabling the mouse or keyboard.

So, I disabled the Input Device Support Mouse, and Mouse Interface in make xconfig and then successfully re-compiled the kernel. After re-booting into the new kernel, I noticed /dev/input/event1 is hooked up to the USB mouse, but using "Device" "/dev/input/event1" inside xorg.conf doesn't work, the pointer jumps all over the place and is unusable.

Is it possible to configure X to only use a USB mouse and totally ignore the Touchpad and Dualpoint?

Kernel: 2.6.19-1.2911.fc6
