Installing Software Suspend 2 for Ubuntu breezy, Kernel 2.6.12
Download the appropriate versions of Software Suspend 2 Kernel patches and the hibernate scripts from
http://www.suspend2.net/downloads/all/.
Applying the kernel patches:
~# cd /usr/src/linux
~# /path/to/software-suspend-version-for-kernel-version/apply
An `All Happy' response from the script confirms the successful application of the patches.
Configuring the new options available:
# Softwareuspend2
CONFIG_SOFTWARE_SUSPEND2=y
CONFIG_SOFTWARE_SUSPEND2_BUILTIN=y
CONFIG_SOFTWARE_SUSPEND_SWAPWRITER=y
CONFIG_SUSPEND2_FILEWRITER=y
CONFIG_SOFTWARE_SUSPEND_LZF_COMPRESSION=y
CONFIG_SOFTWARE_SUSPEND_TEXT_MODE=y
CONFIG_SOFTWARE_SUSPEND_DEFAULT_RESUME2='swap:/dev/resume_partition'
# CONFIG_SOFTWARE_SUSPEND_KEEP_IMAGE is not set
CONFIG_SOFTWARE_SUSPEND_CHECK_RESUME_SAFE=y
# CONFIG_SOFTWARE_SUSPEND_DEBUG is not set
# CONFIG_SOFTWARE_SUSPEND_DEVELOPER is not set
... where `/dev/resume_partition' is the default swap partition -
fdisk -l knows more if in doubt. (Also configurable via the
resume2=swap:/dev/resume_partition/ kernel boot option.)
Finally, the hibernate scripts provides a convenient and configurable way to send the system to sleep. After executing
./install.sh from the hibernate-script source dir, the program gets installed in
/usr/local/sbin/hibernate with the appropriate configfiles in
/etc/hibernate/Basic suspend worked fine - now playing around with the configuration :)
