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.
I got most of my information from:

various Linux sites talking about thinkpads
