Software suspend under Linux
Software suspend
As usual, the following informations are provided as is, with no warranty of any kind. Use this at your own risk.
Software suspend is a kernel patch that provides the ability to suspend execution of the kernel without using any APM BIOS feature. This is really useful either if your BIOS is broken (for instance you have bought a larger disk than the original one and the BIOS is unable to handle it :-() or if you frequently swap from windows to linux because this feature allows you to save your linux session on disk instead of rebooting.
 Software suspension related scripts
The following scripts try to help users in using software suspension. Use option --install to install each script and its configuration file. Edit the latter to tune the settings. Changelog is included in each script.

This script let you suspend your computer smoothly. It makes some
checks before actually suspending to prevent some possible
misbehaviours of swsusp. It restores clock upon resume and start/stop
services such as usb or pcmcia for which devices could change between
suspension and resume.

This script is for ACPI users. It monitors battery power and takes
appropriate action when AC is off to reduce consumption. It also
activates suspension when battery power reaches its end. It provides
also a small xterm with remaining capacity of the battery. |

This patch is against vanilla kernel. The changes are detailed through the incremental patches below.
This version is currently the most stable one. If you can't get swsusp
to work with beta16, you can try more recent releases, but for the
moment beta19 isn't as reliable as beta16, due to big changes in
suspension process.

This is the outdated version of patch for 2.2 kernels. It is adapted from v7c-2.2.19 patch but it is no more maintained.
Software suspend was first developped by Gabor Kuti and he used to maintain a
page for his patch.
