acpid and dbus

I'd like to see some more explanation of how all of these power management/laptop subsystems relate to each other. Do I need acpid now that udev and dbus exist? Will laptop mode tools talk to pm-suspend to initiate suspend on lid close? Or can this be signalled by dbus, or acpid? --VitaminJ 19:32, 5 February 2011 (EST)

I'm pretty sure you do need acpid, else the events aren't picked up. It seems there are some LM connected scripts in the /etc/acpi/ directories, but they don't really do much besides enabling/disabling LM. I guess that's up to the user to decide, but you could provide some suggestions on the wiki for these scripts.--Smartass 10:18, 20 March 2011 (EDT)

Laptop-mode-tools does not disable on AC

I think the command should be:

# touch /etc/pm/power.d/laptop-mode

because in /usr/lib/pm-utils/power.d/ there is a "laptop-mode" file

I think LMT is now obsolete due to systemd+tlp combination; In my honest opinion we should add an initial warning on the top of the page, that says a something like: LMT based on old softwares acpi and cpufreq; today major distribution relies on systemd (Arch Linux too) so your software choice for battery saving/energy optimization/whatelse... is likely to be TLP; let me know what do you think --nTia89 (talk) 13:24, 17 May 2016 (UTC)

Last commit 16 days ago [1]. Besides, if we're adding "warnings" like that to this page, we could likewise add some to TLP e.g. for the system using more power on AC and USB devices that stop working. Closing. -- Alad (talk) 10:54, 1 September 2016 (UTC)
Any link to support this warning? --Fengchao (talk) 09:24, 1 September 2016 (UTC)
