TuxOnIce. Revolutionise the way you start your computer.
TuxOnIce is most easily described as the Linux equivalent of Windows' hibernate functionality, but better. It saves the contents of memory to disk and powers down. When the computer is started up again, it reloads the contents and the user can continue from where they left off. No documents need to be reloaded or applications reopened and the process is much faster than a normal shutdown and start up.

TuxOnIce has a long feature list, including the ability to cancel hibernating or resuming by pressing Escape, image compression to save time and space, a versatile plugin architecture, support for machines with Highmem, preemption and SMP.

The TuxOnIce website (this one) and mailing lists provide support for dealing with issues.

The primary author of TuxOnIce is Nigel Cunningham. A huge thanks must also go to Bernard Blackham, Florent Chabaud, Pavel Machek, Gabor Kuti and Michael Frank along with many others who have tested and contributed to the development of TuxOnIce.
