NOTE: The correct path is /usr/local/etc/xdg/autostart/ibus.desktop

======= Ian' Follow-up Report ==========
After approximately 19 hours of testing PCBSD 8.0-x86 with the legacy
nVidia driver 96.43.16 (compositing off, ibus on), I have not had a
freeze. I've tested heavily with internet and graphics programs and
terminal. The only corruption to the display consisted of minor
speckles visible along the outside edge of terminal windows, usually
on the right side inside the frame. Occasionally, the background
terminal window would display a horizontal band, but the band
disappears the moment that window becomes the focus. A few times, the
title bar would become invisible, but would redraw as soon as the
mouse cursor passed over it. A screen shot is attached to show both
the horizontal band and the minor speckling.
Several hours ago, I removed ibus as per your suggestion and rebooted.
It makes no difference as far as I can tell because the speckling in
terminal windows still remains.
It appears to me that the most important things necessary to have
nVidia legacy cards play nice with PCBSD 8.0-RELEASE is to upgrade to
the 96.43.16 driver and to turn off display effects-compositing.
I will report on the 173.xx.xx series of legacy drivers tomorrow.
