[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.

Fixed my problem on Feisty with my Inspiron 1501

Thanks, works fine with Acer Aspire 5102 with 8.10.

All the best,

As it seams no need to change anything on the new Ubuntu 8.10 Intrepid.

Suspend and resume has been working out of the box for me!

Also confirmed the suspend to disk(hibernate) works for aspire 4720Z. The default suspend to ram(suspend) works so I didn't test it, just left it as is by default.

This is on Ubuntu 9.04 Jaunty Jackalopearoo.

Now I can focus on making games work

I have a Dell Inspiron 9400 I have never been able to get suspend to ram or hibernate to work.

Today read through this entire thread and did some googling after some prelim work got my swap space setup and recognized and s2disk works perfectly.

But s2ram is a bit problematic it suspends but on resume the system freezes I have to do a hard power off.

My Inspiron uses an integrated Intel 945GM. Where can I locate the log that would have the errors encountered while resuming?

Thanks.

I just upgraded to Jaunty, and as I normally do in upgrades, I made the changes outlined in this howto to make my system use s2ram and s2disk. Both commands would work when I ran them from the terminal, but when I selected "hibernate" or "suspend" from the logout menu, they didn't seem to be working.

I discovered that with this upgrade, Jaunty seems to have installed uswsusp into /usr/sbin/, and not /sbin. So, for those of you having the same problem, when you edit /usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux, instead of putting this:

#!/bin/sh

/sbin/s2disk

try this instead:

#!/bin/sh

/usr/sbin/s2disk

You also would need to make a similar change for suspend. This fixed the problem for me so that I could select hibernate or suspend from the menu, rather than having to run s2disk or s2ram from the terminal.

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.
