How I "fixed" my laptop Alps touchpad

[Default User]

My laptop has an Alps touchpad (not Synaptics). Running any FOSS system,
it was too slow. Moving from top to bottom or side to side of the
touchpad only moved the cursor about 1/2 to 2/3 the height or width of
the screen. So I was using a mouse (on a laptop?) instead. What the
hell, it worked. 

Today, running Ubuntu 7.04, I finally figured out a quick fix for the
touchpad. All I had to do was, as root, add one line to the
file /etc/X11/xorg.conf: 

        Option          "AccelFactor"           "0.5"

(BACK UP THE FILE FIRST, OF COURSE!)
Then I rebooted (just logging out of the X session and logging back in
without rebooting did not work). BTW, the acceleration factor of 0.5 was
chosen at randon, it just happened to work. You may need to use a
different value.

It works! For now anyway. And I have freed up a usb port as well. But it
will take some getting used to using a touchpad rather than a mouse. 

Hope this helps someone else.
