ACPI: Standby, sleep, suspend and resume

[Erik Norgaard]

Hi:

I have the following sysctl parameters:

hw.acpi.supported_sleep_state: S3 S4 S5
hw.acpi.power_button_state: S5
hw.acpi.sleep_button_state: S3
hw.acpi.lid_switch_state: NONE
hw.acpi.standby_state: S1
hw.acpi.suspend_state: S3
hw.acpi.sleep_delay: 1

First, I'd like that the screen is switched off when the lid closes, so
I assume that I should set hw.acpi.lid_switch_state to something, but I
don't know what.

Second: Is there a way to manually toggle the sleep state so I can
create a menu item "sleep" or "standby"?

Last: When the laptop goes into some suspend mode - I don't know which -
I don't know how to bring it back alive except for rebooting. What is
the secret key combination? (typically).

Thanks, Erik

These are my settings. This is for a thinkpad T42p, your settings may be
slightly different.

sysctl:

hw.acpi.supported_sleep_state: S3 S4 S5
hw.acpi.power_button_state: S5
hw.acpi.sleep_button_state: S3
hw.acpi.lid_switch_state: NONE
hw.acpi.standby_state: S1
hw.acpi.suspend_state: S3
hw.acpi.sleep_delay: 3

/boot/loader.conf

snd_ich_load="YES"
if_ipw_load="YES"
wlan_load="YES"
wlan_wep_load="YES"
acpi_ibm_load="YES" <---- for thinkpad

If I close the lid the T42p goes to standby, opening wakes up. The sleep button
fn-F4 does a suspend, again opening the lid does a resume. I have not figured
out suspend to disk but for my purposes suspend draws power so slowly, I have
not bothered.

It may be that you do need something set for hw.acpi.lid_switch_state, I do not.
Resume does not correctly redraw the X-windows background, but it writing this I
noticed I put:

notify 10 {
match "system" "ACPI";
match "subsystem" "Lid";
action "/usr/X11R6/bin/xrandr -display :0.0 -s 0";
};

inside of the comments in /etc/devd.conf.

The devd.conf change works. Trying to help you helped me. I hope this
information aids you as well. Without the xrandr, I got black and white stripes
randomly for the background.
