hi,
i've been browsing through the pm-utils code since fixing some suspend
issues on my laptop (running ubuntu hardy) and it looks to me like it'd
be pretty straightforward to get pm-utils to support tuxonice in
debian-based distros. i think not much would be required beyond a
couple of small changes in pm-action and functions; first we slightly
improve the test for suspend-hybrid capability (in pm-action):
case "$ARG" in
suspend)
grep -q mem /sys/power/state || exit 1
;;
hibernate)
grep -q disk /sys/power/state || exit 1
;;
suspend-hybrid)
grep -q mem /sys/power/state || exit 1
grep -q disk /sys/power/state || exit 1
[ -d /sys/power/tuxonice ] || [ -x /usr/sbin/s2both ] ||
exit 1
and in functions, change do_suspend_hybrid():
do_suspend_hybrid()
{
if [ -x /usr/sbin/s2both ]; then
/usr/sbin/s2both -f $S2DISK_CONF $S2RAM_OPTS
elif [ -d /sys/power/tuxonice ]; then
echo 3 > /sys/power/tuxonice/powerdown_method
echo -n "platform > /sys/power/disk
echo -n "disk" > /sys/power/state
else
exit 1;
fi
}
one could make other refinements, in particular allowing users to set a
preference when multiple suspend options are present; but i think these
would be sufficient in principle. let me know what you think & if you
would be interested in patches. thanks much,
matt
