In OSX there is this restart and resume feature, that makes every window of every application (that supports this feature) resume after a system reboot, even unsaved new documents, mails, images etc.
I wonder, if and how it is possible to imitate this feature on an Ubuntu system. There is tuxonice but I am not quite sure if that actually does what I want.
To clarify, I am not talking about hibernating or suspend to disk. After a true reboot and even after hard resetting the machine everything is back as before. I use it with TextEdit to hold notes a lot, but also with unfinished emails in Mail. It would be really cool to have this on Ubuntu as well.
