Hello, I would like to know if there is a way to use the suspend, sleep, etc...
(in fact the >>>>
powermanagement function) with an acpi laptop?
I got acpid to work by doing the following:
1. Turn off apmd and enable acpid using redhat-config-services. If you have an ACPI machine, you don't have an APM machine. I don't know why both are enabled by the default installation.
2. For test purposes, set up a battery monitor. On the GNOME desktop, I used battstat-applet; I don't use KDE so I can't help you there. When things are broken, it will give you no useful information at all.
3. Add the following code to /etc/rc.local: ----snip---- if [ -d /proc/acpi ]; then for module in /lib/modules/$(uname -r)/kernel/drivers/acpi/*
do insmod $module done fi ----snip-----
This script will load modules for the various ACPI functions. I located this in the fedora-list archives, and cleaned it up to suit my style. The $(uname -r) part extracts the kernel version so that this continues to work when you change kernels.
4. Reboot the system and add
acpi=on
as one of your boot parameters. Make this permanent by editing /etc/grub.conf.
Once I did these things, I discovered the following:
The battstat-applet properly displayed the battery level and indicated when I was on AC power.
The system would turn completely off when I halted, rather than simply halting the OS and leaving the computer on.
I have seen postings that say that suspend does not work under FC1. I've also not managed to respond to events from the power button, lid, etc; because I don't know how to specify events for acpid. The man page for acpid explains which files configure it, but not precisely what you can configure. I did notice that the screen would turn off after a time, but I don't know what exactly made that happen.
What this did do for me is to give me status on the battery, the ability to cleanly shut down the system, and the confidence that I wasn't likely to melt my processor. I hope this will get it going for you, so you can figure out how to go farther.
Good luck. I hope this helps. Erik
I have had good luck with FC1 and ACPI on my Dell Inspron 600M - I can "put it to sleep" thus (must run with root privs.):
#!/bin/bash
# shut down screen (activate screensaver)
xscreensaver-command -activate
sleep 2
echo 1 >/proc/acpi/sleep# machine is now sleeping, pressing power button # will "wake it up"
# next line gets the mouse back from X never-never-land
/sbin/service gpm restart
echo back from sleeping...-- John Pantone Objectech Corporation
