It appears to me (empirically, not from code inspection) that there may
(at least in some cases) be a delay between the time hald(8) starts and
the time that X can actually use it in a useful way to determine
information about the mouse and keyboard.
I ended up augmenting my xdm(1) start-up script's "start" stanza with:
...
# REQUIRE: ... hald ...
...
. /etc/rc.subr
...
until hald=$(check_process hald-addon-mouse-sysmouse); [ -n "${hald}" ]; do
info "$name start-up waiting for hald-addon-mouse-sysmouse"
sleep 1
done
until [ -r /proc/${hald}/status ]; do
info "$name start-up waiting to read /proc/${hald}/status"
sleep 1
done
# This can actually be done as a single expression, but that helps
# neither debugging nor comprehension.
hald_start=`awk -F "[ ,]" '{print $8}' /proc/${hald}/status`
now=`date "+%s"`
# This was determined empirically
hald_delay=8
wait=$(($hald_start + $hald_delay - $now))
if [ $wait -gt 0 ]; then
info "$name start-up waiting $wait seconds for hald-addon-mouse-sysmouse"
sleep $wait
fi
...
With the above, I've only had the "non-responsive keyboard & mouse"
syndrome a couple of times (out of about 2 dozen or so xdm start-ups)
in the last several days.
Mind, I don't consider that a "solution" -- it's a hack. But if
it helps.... :-}
Peace,
david
