Hoary: suspend and hibernate report on HP nc6000

[Mario Vukelic]

My PC is an up-to-date Hoary, hardware is a HP nc6000 laptop. However, it was
"sidegraded" from Debian sid 2 months ago.

After I managed to get basic acpi stuff working (see bug #12194 for the history),
I get a glimpse of working power saving modes:

sudo /etc/acpi/actions/hibernate.sh:
Basically works without me having to change anything. The only problem is that
when I send the machine to hibernate, it needs several minutes actually doing so
(all the while I see a console screen, and from the percentages it _slowly
counts up, it seems it is writing mem to disk). I don't know if this is "normal"
though

sudo /etc/acpi/actions/suspend.sh:
I get a console screen briefly, and then the system goes to suspend. However
when it wakes up again, I get only a white X screen and can't give any input.
Switching to another VT is impossible too.
I have played with the options in /etc/default/acpi-support, but to no avail. So
far I have tried (each setting changed on its own):
ACPI_SLEEP_MODE=standby
POST_VIDEO=false
USE_DPMS=false
DOUBLE_CONSOLE_SWITCH=true
LOCK_SCREEN=false

When I choose "hibernate" or "suspend" from the Gnome Desktop "System" menu,
nothing happens at all.

If I can supply more info, or test something, please tell me

Some more info regarding the time needed to hibernate:
First the console screen says swsusp is copying pages. This goes fairly quickly,
around a minute or so. Then it says that it writes the memory to the swap
partition (and counts up percentages). This is the part that lasts seemingly
forever - I timed 11 minutes. My laptop has 512 MB RAM, but even for that, 11
minutes seems excessive (and not particularly power saving).

I tried using the /etc/acpid/sleep.sh on Hoary.
$ sudo /etc/acpid/sleep.sh

The machine just went to sleep while the cpufan and the power button showed
activity
the machine wont comeback ... I did everything including holding the power
button on
for like 5 minutes... The network was showing some activity. I pulled out the
battery
to reboot the machine.

The hibernate worked as a charm and I even get the video back X comes on with
the same
apps that I was using before I did a hiberate.

No it goes off in about half a minute unless im grossly missinformed about the
concept "off."

Yes.Im running hoary on a nc6000.

No, followed wiki/HoaryPM and ran /etc/acpid/hibernate.sh. and when I push the
power button again linux boots and takes me to X takes about 1-2 minutes.

Being optimistic because of Pankaj's success, I played a bit more, with the
following outcome:

First, I found out that my install of acpi-support was somehow wrong: the
hibernate scripts were in /etc/acpi/action instead of directly in /etc/acpi. I
suspect this may be because of my previous playing with PM in Warty (there once
was a tarball in the Wiki that replaced Warty's /etc/acpi).
I deleted /etc/acpi and reinstalled the package with dpkg -i --force-confmiss
/var/cache/apt/archives/acpi-support_0.21_i386.deb

The grub config was already ok as per wiki/HoaryPM, and the hoary install is up
to date

After that, I see an improvement in hibernating:
* The screen goes immediately blank, not displaying the swsusp progress info
that I mentioned in a previous comment
* However after the screen blanks, I still have a running fan, a lit harddisk
LED, and blinking lights at the ethernet port. In addition, the "sound off"
button at the left front lights up
* After 8 minutes, all the mentioned lights go out and the fan stops. When I
press the power button now, the laptop wakes up again and is ok. If I press the
power button before the lights go out, nothing happens, but I haven't tested
whether this messes anything up

Compared to my previous comments, this is a marked improvement -- hibernating
previously lasted 15 minutes. However it is still far from optimal.

Suspend still doesn't work, with the same symptoms Pankaj reported

I was facing problems with the upgrade from warty... with a freash install of
hoary from the cd hibernation and sleep worked out of the box.
