Trying again to see if anyone had any other ideas.
In addition:
The acpid daemon is running.
The same machine when booted into windows will automatically go to
powersave mode when the power cable is removed.
TIA

original post (4th March):
Hello,
I have been trying to get acpid to receive events on gentoo without any
success.
I an on kernel 2.6.17 (with rev 10 gentoo patched)
acpid: 1.0.4-r4
Toshiba Tecra M3
I have been following the guide at:
http://www.gentoo.org/doc/en/power-management-guide.xml
I'm on 2.6.17
So, whatever they suggested to compile in the kernel or as a module that
is what I have done.
When I look at /var/log/acpi no events are being generated.
With this test :
on_ac_power && echo AC available || echo Running on batteries
It shows "AC available" when the ac is plugged in, take the cable out,
and it shows "Running on batteries"
Code:
# acpitool -e

wakeup devices :
I can modify this:
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
and the processor speed with follow the governor which I set.
I can also run: acpitool -l 4
for example, and dim the lcd display.
Also, I have th battery indicator applet in gnome, this also changes
correctly with respect to having the power connected, or not.
Most things seem to work as they should, except acpid is not receiving
events.

The AC and battery modules are compiled in kernel as the guide suggests.
# acpi_available; echo $?
0
# grep -i "^config_acpi" .config
CONFIG_ACPI=y
CONFIG_ACPI_AC=y
CONFIG_ACPI_BATTERY=y
CONFIG_ACPI_BUTTON=m
CONFIG_ACPI_VIDEO=m
CONFIG_ACPI_FAN=m
CONFIG_ACPI_PROCESSOR=m
CONFIG_ACPI_THERMAL=m
CONFIG_ACPI_TOSHIBA=m
CONFIG_ACPI_BLACKLIST_YEAR=0
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_SYSTEM=y
# lsof |grep "/proc/acpi/event"
acpid 13843 root 3r REG 0,3 0 4026532088
/proc/acpi/event
Even if I run strace against acpid I can't seen anything happening.
One interesting though, if I do : modprobe button
then every 30 seconds or so I get:
received event "battery BAT1 00000080 00000001"
Even when i do rmmod button I still keep getting these events.
The only way to go back to "normal" behaviour is to reboot.
Any suggestions as to what might be my problem here ?
TIA
Nigel.
