ubuntu-minimal/Server does not depend on acpi-support

xfce needs to be able to deal with non-ACPI suspend keys (ie, those that generate keycode 142)

I don't understand fully

You suspended in the installation? With the CD in the drive? Didn't it just reboot from the cd then, or are you 100% sure, that is was a real suspend?

Boot from Installation CD. In the screen I have the new menu of the CD. Then I press the "suspend button" and after few seconds the system is supended. The power is off (but the power led blinks) and the cd-rom spin down. Then (after some minutes) I press the "suspend button" again. The power is on again, the cd-rom is running again and I'm in the same state in the installation menu (no reboot in any way, I'm totally sure). Then I think "wow, supends is running in the new Ubuntu".

But after the installation process (and after discover a bug in the framebuffer mode) I tested the "suspend button" from de text mode. Nothing happends.

To test the "suspend" facility better I install the Xfce4 and test if the "suspend" mode from the menu works at all, but not. Nothing happends again.

I think that it's not a Xfce4 problem because suspend runs in "installation menu" but not in the system installed and running, with and without Xfce4.

Something is loaded or activated before the new installation menu that makes the "suspend button" works.

I see all the "dmesg" log but nothing. No errors about this feature.

Thanks. I hope that this explains it better.

Please do

sudo tail -f /var/log/acpid

and press the suspend key. Does anything relating to sleep.sh appear? If not, your suspend key generates a keycode and not an ACPI event. It's up to your desktop to catch that and deal with it appropriately.

Ok, that's more interesting. What does your

/etc/acpi/events/sleepbtn

file look like?

There is only "powerbtn" file.

You're missing the acpi-support package. Colin, any idea how that could end up being the case?

After acpi-support installation (a lot of thanks!) I need to edit /usr/share/acpi-support/Compaq.config to add my laptop:

        "Evo N600c"*)
                ACPI_SLEEP=true
        ;;

Please add this lines to this file by default to help new users. And improve the "laptop detection" to install this packages (radeontool, laptop-mode...) by default. Thanks.

Since Ignacio did the "Server" install method and that won't pull in 'acpi-support' (whereas, the LiveCD has 'ubuntu-desktop' which pulls it in).

  $ apt-cache rdepends acpi-support
  acpi-support
  Reverse Depends:
    ubuntu-desktop
    xubuntu-desktop
    ubuntu-desktop
    powermanagement-interface
    kubuntu-desktop
    edubuntu-desktop

So one or more:

  (a) Ignacrio, you need to 'sudo apt-get install xubuntu-server'
  (b) 'ubuntu-minimal' should depend on 'acpi-support' on i386 and amd64

Thanks for the white-list entry, this needs adding to 'acpi-support'.

Whitelist Compaq EVO as having working suspend.

This isn't an espresso issue. Indeed, the reporter didn't even use espresso at all.

Whether this is a but or not depends on whether power-management should work on server-installs or machines without a desktop running.

 acpi-support (0.65) dapper; urgency=low
   * Whitelist Compaq Evo N600c has working SLEEP [Malone: #36838]

Power management isn't generally appropriate for a default server install; the odd server admin who wants to suspend their server can install the package explicitly (or just install it as a desktop).

Simplicity++

The Whitelist was added earlier.
