[HowTo]: Fix suspend and hibernate on laptops

[zeekoe]

For me, it worked using uswsusp right after updating to Gutsy. Now it's gone again. What I did to fix it:

* Did what was described here:
http://knowledge76.com/index.php/Suspend_and_Hibernate
* Did some basic tests from here:
http://www.mjmwired.net/kernel/Docum...-debugging.txt
The reboot/disk test showed directly that mysql was a problem. I disabled mysql, did some tests again, and it worked fine! This is now my custom hibernate script:
#!/bin/bash
/etc/init.d/mysql stop
echo platform >/sys/power/disk
echo disk >/sys/power/state
/etc/init.d/mysql start

Don't think this is using swsusp, but it works... who cares
By the way, the Menu -> Shutdown -> Hibernate thing does still not work; it blanks the screen for a few minutes and then just returns.

(sorry for me english, but i don'ts speak that very well.. i speak spanish)

i try this in a laptop packard bell easynote mx36-u-2080

I'm running compiz fusion with the latest fglrx driver of ati propieatry, with a intel core duo 1.73ghz and 1gb ram... on ubuntu gutsy

when i try... it seems like to the resume image is done.. but when i reboot the sistem (s2disk) the screen freeze and i only see a message like that:

resume: Image loadding succesfull.

But the sistem don't start...
What can i do???

other thing the command s2ram doesn't exists... i see only a s2disk and s2both... i supose s2both = s2ram ...

[chiefmanyrabbitguteat]

For me, the fix worked only when I entered the command:

 s2ram --force

from the terminal. To fix this, I had to do the following:

sudo aptitude install uswsusp

After that, I pulled the 0.7 version off of

http://packages.debian.org/sid/i386/uswsusp/download

and installed it. I don't know if it is necessary to install the one from the Ubuntu repos, but that's how I did it.

Test it out: Use

sudo s2ram --force

If that works, back up the following file:

sudo cp /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux.bak

Then, edit the original:

 sudo gedit /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux

Replace all of the text with the following:

#!/bin/sh

/usr/sbin/s2ram --force

Now, it works like a charm!

P.S. Sometimes I get a white screen after I suspend, and all I need to do is enter my password and hit enter.

Suspend works OK now on my HP Compaq nx7400 laptop.

Anyone been able to get hibernate to work as well?

both hibernate and suspend now work on my IBM X60

On a Dell Inspiron 5160, I've managed to get s2both working properly from the command line using sudo s2both, which was a huge ordeal. However, pressing the Fn-Esc (Suspend) does nothing at all. After running "xev", no events are reported for this key event. All of the other Fn keys report events. Furthermore, pressing the power button does nothing as well. Performing the suspend or hibernate from the Gnome menu appear t suspend and hibernate, but when powered on again, they screen is blank but the system appears to be running.

Does anyone know how to enable these events?

Running Gutsy, kernel version 2.6.22-14-generic.

Thanks!

Hi,
I have a compaq Evo n610c and I managed to get suspend to ram working. Not using s2ram.
I added to grub kernel line "acpi=off".
It just work pressing the suspend button, not with the suspend icon. Also hibernation does not work anymore. Maybe somebody with the same laptop can fix the hibernation and suspend with the icons.

PS.
Does anybody knows what script is executed when I press the suspend button and I have ACPI deactivaded?

thanks

My suspicions were correct. The problem is not Ubuntu, it is the BIOS. It does not properly report all ACPI messages. I found this link where they discussed how to patch it on the fly:

http://bugzilla.kernel.org/show_bug.cgi?id=1752#c103

This made my power and suspend button start working, but after suspending, the resume does not work. The system powers up again, but gets stuck before X starts.

Any recommendations?

I got suspend working properly. After following the above steps in the link, then the instructions in this link:

https://help.ubuntu.com/community/Nv...cumentation%29

everything works fine. Hope this helps someone else.

I get a weird message

s2disk: Could not stat the resume device file. Reason: No such file or directory
