Most people need hibernation for their laptops.step is to install a tool called «uswsusp»
sudo apt-get install uswsusp
And by typing the below command you check if the suspend function works now….
sudo s2ram
Same goes for hibernation
sudo s2disk
Now once this is done, and all of the above commands work, they can be replaced with the old non-working commands that come with ubuntu.
But attention, before editing the system files, always make sure you back up the files in case something goes completely wrong.
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
This step is to replace the old commands with the new commands in
hal-system-power-suspend-linux
sudo nano /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux
paste the following:
#!/bin/sh
/sbin/s2ram –force
hal-system-power-hibernate-linux
sudo nano /usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux
paste the following again:
#!/bin/sh
/sbin/s2disk
I get a crash on rebooting from hibernate after doing this…I have to reboot again with previous successful boot, and then it works.
Is there any way to skip the crash?
instead of using uswsusp, i used the acpi scripts /etc/acpi/sleep.sh and /etc/acpi/hibernate.sh. works for me.
Oh. Dear Lord, why the command so long. Is it possible that ubuntu will fix this bug via update?
In my case, the location of s2ram and s2disk was in /usr/sbin, instead of /sbin.
On my Dell Latitude X300, I’ve found that it’s closing the lid that causes problems, not suspend. If I press the alt-esc, the computer suspends and comes back alive fine. But if I close the lid, which I’ve also set to suspend, it crashes. I tried setting the “close lid” to blank screen and also tried hibernate, and the computer crashed in both instances.
With Ubuntu 9.10, I have to change the /etc/pm/config.d/00sleep_module file to make power manager use uswsusp.
# The sleep/wake system to use. Valid values are:
# kernel The built-in kernel suspend/resume support.
# Use this if nothing else is supported on your system.
# uswsusp If your system has support for the userspace
# suspend programs (s2ram/s2disk/s2both), then use this.
# tuxonice If your system has support for tuxonice, use this.
#
# The system defaults to “kernel” if this is commented out.
SLEEP_MODULE=”uswsusp”
Since 9.10, I was unable to use uswsusp, simple because my computer no longer boots if ‘resume’ is present in kernel options. Either it takes too long or it doesn’t boot al all. But I glad the dennis j is able to use uswsusp in Ubuntu 9.10.
If I disable display effects then suspend works normally!!

I have the same problem with the lid of the Dell Latitude X300. The computer hangs when you close the lid. Help anyone? Thanks!
