Thank for the response, Hika.
pgrep -u mythtv mythfrontend.re
returns no error (I don't have mythfrontend running at the time, so it
returns nothing)
In conf.d, I have:
# User id that all the processes should run as.
MYTH_UID="mythtv"
mythtv is a valid user, and the home directory is there. Also, if the
MYTHUID were bad, wouldn't the init.d script bomb in here?
start-stop-daemon --start --quiet --background \
--user ${MYTH_UID} \
--exec /usr/bin/startx \
-- -- ${MYTH_XOPTS} vt${MYTH_VT}
