Package: i8kutils
Version: 1.33
Severity: important
Dear Maintainer,
The package i8kutils has been installed on an old DELL Latitude C610 computer
running DEBIAN Wheezy.
i8kmon has been configured to start automatically at boot time.
Here is what the various i8k utilities report in succession.
more /proc/i8k
1.0 A16 XXXXXXX 39 0 0 0 0 -1 0
Notice the value -1 corresponding to the AC/battery status. XXXXXXX replaces
the id of the computer for privacy reasons.
1.0 A16 XXXXXXX 41 0 0 0 0 1 0
Notice the value 1 for the AC/battery status (AC on, correct).
Launching manually i8kmon with i8kmon --nodaemon in a terminal window results
in the following:

Notice the value 0 for the AC/battery status (battery on, incorrect), and the
fact that the tool assumes the temperature control range corresponding to an
unplugged machine (39 - 60 degrees). Notice that when launching this command
in a terminal window, there is already a i8kmon daemon running in the background
(but which does not seem to leave a log of its own).
Repeating the whole exercise after unplugging the power cord, hence running on
a battery, gives the following results.
more /proc/i8k
1.0 A16 XXXXXXX 46 0 0 0 0 -1 0
Notice the value -1 corresponding to the AC/battery status.
i8kctl
1.0 A16 XXXXXXX 46 0 0 0 0 0 0
Notice the value 0 corresponding to the AC/battery status (battery on, correct).

Notice the value 0 for battery on, and the selection of temperature ranges
corresponding to the battery (correctly this time).
There is no user configuration file ~/.i8kmon.
File /etc/modprobe.d/i8k.conf is as follows:
options i8k force=1
File /etc/i8kmon.conf is as follows:
# /etc/i8kmon.conf
# Control fans automatically, but keep user interface
set config(daemon) 1
set config(auto) 1
set config(verbose) 1
# Parameters for user interface
set config(timeout) 4
set config(unit) C
set config(t_high) 75
# Controls, derived from i8kfangui for Windows XP.
# It seems that the C610 actually has one small (left, single speed)
# and one large (right, two speeds) fan.
set config(0) {{0 0} -1 48 -1 50 }
set config(1) {{0 1} 37 58 39 60 }
set config(2) {{0 2} 47 68 49 70 }
set config(3) {{1 2} 57 128 59 128 }
The following files or folders do not exist and have not been created during
installation of Linux:
config(proc_ac24) = /proc/acpi/ac_adapter/0/status
config(proc_ac26) = /proc/acpi/ac_adapter/AC/state
config(proc_apm) = /proc/apm
It may be that there is a deficient setup of ACPI in DEBIAN Wheezy for that
computer that results in a strange behaviour of i8kutils, but in any case:
1) If i8kutils depends on some unavailable component in the operating system
power management setup, then it should warn explicitly about that dependency.
2) i8kctl seems to find the correct value of the AC/battery status, but i8kmon
does not. How is this at all possible?
3) Why does /proc/i8k report a value of -1 whatever the AC/battery status?
No newer version of i8kutils has been installed, the only stable version
proposed by Synaptic being 1.33.
I would be grateful for an explanation of this discrepancy, and if possible on
how to make i8kmon detect the AC/battery status properly.
Many thanks in advance
