Ubuntu 11.10 無法Suspend的解決方法

Ubuntu 11.04在我的laptop上可以suspend，但是升級到/11.10後就沒辦法了，google了一圈，找到了一個解決方案，原文如下：

I've had some difficulty getting uswsusp to be default on my other laptop. So here are the 3 approaches (best option first):

A1. Set correct pm-utils options

Code:

gksudo mousepad /etc/default/acpi-support

...and uncomment the line:

Quote:

# SAVE_VIDEO_PCI_STATE=true

...so that it reads

Code:

SAVE_VIDEO_PCI_STATE=true

...save the file.

A2. Recreate initramfs

Code:

sudo update-initramfs -u

A3. Reboot and try using the menu options.

------------------------------------------------

If you have no luck with the above approach, here is the second approach:

B1. Set uswsusp as default in place of pm-utils:

Code:

gksudo mousepad /etc/pm/config.d/defaults

...and add the following content:

Code:

SLEEP_MODULE=uswsusp S2RAM_OPTS="-f -s -p -v"

...save the file.

B2. Recreate initramfs

Code:

sudo update-initramfs -u

B3. Reboot and try using the menu options.

------------------------------------------------

And finally, if neither of the above 2 options work, try this approach:

C1. Create new pm-suspend file:

Code:

gksudo mousepad /usr/sbin/s2ram_override

...with the following contents

Code:

#!/bin/bash /usr/sbin/s2ram -f -s -p -v

...save the file then make it executable

Code:

chmod +x /usr/sbin/s2ram_override

C2. Backup the current pm-utils suspend file:

Code:

sudo mv /usr/sbin/pm-suspend /usr/sbin/pm-suspend.BAK

C3. Link in the s2ram suspend file:

Code:

sudo ln -s /usr/sbin/s2ram_override /usr/sbin/pm-suspend

C4. Try using the menu suspend option.

我用了option B ，解決了我的問題。
