Bug Description

For some time now (since dapper) I have not been able to get my thinkpad to suspend using the Fn+F4 key. Suspending from the context menu from gnome-power-manager applet works. I can also get the thinkpad to sleep from the System->Quit menu. The suspend mechnism seems to be fine, however, something is wrong with the suspend key.

I have finally been able to investigate this. When the Fn+F4 key is pressed, the acpi daemon detects it and runs /etc/acpi/sleepbtn.sh. The file sleepbtn.sh issues 'acpi_fakekey $KEY_SLEEP'.

I understand that gnome-power-manager is supposed to listen for these events produced by acpi_fakekey. I ran g-p-m with --no-daemon and --verbose. This is the output I see when I press Fn+F4:

[watch_device_condition_cb] gpm-hal.c:953 (14:58:14): emitting device-condition : /org/freedesktop/Hal/devices/platform_i8042_i8042_Kbd_Port_logicaldev_input, ButtonPressed (sleep)

[gpm_info_event_log] gpm-info.c:611 (14:58:14): Adding 11 to the event log

This is odd (and ironic): "doing nothing because the suspend button has been pressed". Shouldn't g-p-m suspend the machine?

I have finally figured out how to solve the problem. I opened up gconf-editor to find the key /apps/gnome-power-manager/action_button_suspend. It was set to the value "nothing". I changed that to "suspend". That solved the problem.

Therefore this bug reduces to the question (perhaps for upstream): is that the default value for that key? Or how did I end up with that value in that particular key -- I've never edited gconf-editor before.

I think the default action for the suspend key should be to suspend -- and not to silently ignore the button. This is specially important given that the other special keys (display on/off, wireless kill switch, lock-screen, etc.) on the thinkpad actually do work.

Hi Ali, there is a whitelist based on whether Suspend is known to work on that particular machine; wonder if that is it. Can you please past the output from:

  cat /var/lib/acpi-support/*-*

Upstream we have the default for the suspend key to be "suspend" - ubuntu patch this to "nothing". I'm not sure I understand this one either (upstream author talking). Richard,

Thanks for the ACPI data. If you can confirm that T60p is working correctly, we can whitelist suspend by default in future.

I can confirm that suspend works perfectly on my Thinkpad T60p.

g-p-m defaults to suspending when you hit the Suspend button now.

I suddenly have the same issue on my Samsung X20 XVM 1730 V laptop.
I am almost certain that it worked until a couple of days ago. I haven't changed the configuration. Has any update changed the /apps/gnome-power-manager/action_button_suspend recently? Does any process change that setting?
