I would like my laptop to ignore system APM suspend and standby requests
from BIOS calls when on AC power.
The relevant (Woody default) part of /etc/apm/apmd_proxy reads:
==========
SUSPEND_ON_AC=false
[ -r /etc/apm/apmd_proxy.conf ] && . /etc/apm/apmd_proxy.conf
if [ "${SUSPEND_ON_AC}" = "false" -a "${2}" = "system" ] \
&& on_ac_power >/dev/null; then
# Reject system suspends and standbys if we are on AC power
exit 1 # Reject (NOTE kernel support must be enabled)
fi
==========
and /etc/apm/apmd_proxy.conf has correctly set:
==========
SUSPEND_ON_AC=false
==========
However, the laptop will enter standby mode even on AC power.
What makes me wonder, is the note "Reject (NOTE kernel support must be
enabled)". The APM related configuration of my kernel is
This note just means that you must have APM support compiled into the
kernel and turned on. From what you write that appears to be true.
You'll need to debug this a little to find out what is really
happening. That conditional test has three separate components;
failure of any one of the three components will cause the suspend to
continue.
So, for example, you could add lines like this just prior to the
decision in "/etc/apm/apmd_proxy":
echo "ARGS = ${1},${2}" >> /tmp/apmd-trace
echo "SUSPEND_ON_AC = ${SUSPEND_ON_AC}" >> /tmp/apmd-trace
if on_ac_power > /dev/null; then
V=true
else
V=false
fi
echo "on_ac_power = ${V}" >> /tmp/apmd-trace
Then do the operations and see what shows up in the output file.
