Public bug reported:
Binary package hint: acpi-support
In 6.06.1 LTS, /usr/acpi/power.sh explicitly calls
laptop_mode start
and
laptop_mode stop
This means that the preferences specified in /etc/laptop-mode/laptop-
mode.conf are not honoured.
Instead, power.sh should simply call
laptop_mode auto
in both cases. That way the user's preferences as to when laptop mode
will be used will be honoured.
The specific bug that was hitting me was that laptop mode was being
disabled when AC power was reconnected, despite having set
ENABLE_LAPTOP_MODE_ON_AC to 1 in laptop-mode.conf.
Also, power.sh is explicitly changing the hard drive spindown and power
management behaviour by calling hdparm (with fixed, uncofigurable
values). It should leave this to laptop_mode, which already has
completely configurable functionality to do this.
