[HowTo]: Fix suspend and hibernate on laptops

[Bluecircle]

If the normal suspend and hibernate buttons don't work, you can try this little hack.

First get uswsusp:

sudo apt-get install uswsusp

Now, test out suspend to see if it works:

sudo s2ram

If this does not work, you can use

sudo s2ram --force

Next, try out hibernate:

sudo s2disk

Now, if one or both of these commands work and you would like to use them, we need to change the command on the shutdown menu to this.

Note: This part is for FEISTY AND GUTSY ONLY!!! The scripts in Edgy are stored in "/usr/share/hal/scripts" and have different names AFAIK. If someone running Edgy could tell me what the files names are I will add it here.

First, backup your original files:

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

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

Now, edit these two files and replace all the code with this:

hal-system-power-suspend-linux

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

#!/bin/sh

/sbin/s2ram --force

hal-system-power-hibernate-linux

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

#!/bin/sh

/sbin/s2disk

if this breaks stuff, just restore the backup files you made.

Good luck!

I know few people having this problem in feisty I will ask them to try this.

On my laptops there are no problems either on Edgy or Feisty.

Good work though.

Excellent!

This works on my HP Pavilion DV5215us, with xgl and beryl enabled on Feisty

But, after I hibernate or suspend, my Hibernate and Suspend buttons from the Log off menu are gone!

UPDATE: Sound didn't work, I have to reboot to get it back.

Thanks, Bluecircle. The kernalspace (?) suspend/resume stuff (what comes by default) never worked properly on my Toshiba A105. I spent some time long ago trying to figure it out, and eventually because satisfied with only hibernate.

A couple weeks ago, after some update undoubtedly, fan control started to be flaky on resume---the laptop would sometimes get VERY hot! But following your guide, now suspend and hibernate both seem to work fine.

The only strange thing I get is that upon resume, Gnome Power Manager reports that there was a problem suspending. So I have to click a checkbox to make that disappear.

Probably, the permanent installation of the alternative hibernate routine is safer the way described in the link. I have applied it with success (Dell Latitude D810) under Feisty

Many thanks Bluecircle, I will give a try and report back.

tnx!! works fine here

Seems to work fine here too. I have an Asus M2400N Centrino Laptop. It's like 4 years old now.
I will have to play around with it a little more, but the test run I just did went fine.
Thank you very much!

Thanks for the post.

I tried s2disk and found it resumes much faster (50 secs v 84 secs), than the default hibernate on my Compaq n610c. So far s2ram does work on this system as i can not resume. I think the ATI graphics controller is not recovering correctly and I will try this again when the later uswsusp0.6 gets release as this adds more options such as -v (save the PCI config space for the VGA card).

If anyone has a Compaq n610c and has s2ram working, please let me know what settings you are using and also report the s2ram -i output to the developers, thanks.

I will try s2disk and s2ram on my work HP nw8440 laptop soon.

No luck on my Dell inspiron 8600--suspend and hibernate both worked for me in Dapper, but not in Feisty. I've tried several solutions listed here in the forums, but no dice. Everything seems to go down nicely, even with the commands listed in this thread, but when I power up, I get nothing after grub. Does anybody know why the solution listed in this thread works? I'd really like to track down this problem and get it working. Otherwise, I'll have to try and install Dapper again or Edgy. Thanks. Here's my sudo s2ram -i output, if it means anything...

This machine can be identified by:
sys_vendor = "Dell Computer Corporation"
sys_product = "Inspiron 8600 "
sys_version = ""
bios_version = "A14"
