"The first annoyance was the Synaptics touchpad control. The
machine includes a hardware switch to disable the touchpad, but it
doesn't work. Fortunately I can turn off the touchpad with the
GNOME Control Center's mouse control dialog. Unfortunately the
process also switches my Fluxbox theme background to the Ubuntu
default image. That image is nice, but I didn't ask for it and I
don't like the system switching to it without my approval. I
searched Google for an alternative and found the synclient utility.
Alas, that software requires a configured SHMConfig, so I went back
to Google to find out how to enable SHMConfig.
"My first attempts were made by adding appropriate lines to the
meager /etc/X11/xorg.conf, to no avail. I then discovered that
xorg.conf is no longer where the appropriate changes should go. X11
input devices are now defined and registered in the HAL .fdi
configuration files located at /etc/hal/fdi/policy/."
