General

Software Suspend 2, also called "swsusp2" and "suspend2", is an implementation of suspend-to-disk functionality in the form of a Linux kernel patch and several userspace utilities. It is an alternative to both the BIOS-driven hibernation feature found on most ThinkPad models, and the "software suspend" functionality built into recent Linux kernels.

Compared to the alternatives, Software Suspend 2 has some unique features:

  • The ability to compress the memory image as it is written to disk, thereby reducing suspend and resume times.
  • Saving the memory image into the swap partition or a file on a normal filesystem, instead of a dedicated partition
  • Cancelling a suspend in progress
  • Control over amount of RAM written to disk -- can (optionally) discard cached disk blocks to reduce suspend and resume times
  • Textual and graphical UI (optional)
  • Improved reliability under some circumstances -- if the alternatives don't work, try this one!

Since it is implemented purely in software, Software Suspend 2 is in principle machine-independent and should work on all modern ThinkPad models. However, in some cases problematic driver need to be unloaded before suspension.
