PM-utils 1.3.0-rc1 is not available for testing. Notable changes from the pm-utils 1.2 series:

* We now have a suspend-hybrid method that does not rely on tuxonice or userspace suspend/resume. It initially suspends the box, and sets an alarm to wake up in 15 minutes. If the system is not resumed before the alarm goes off, it will wake up and hibernate. You should be sure hibernate works before using this mode -- if the system fails to hibernate, it will not go back to sleep on its own (working around this involves better reporting from the kernel about the last sleep state -- I have a patch forthcoming for that), and if you cannot resume from hibernate you may as well have not even tried to hibernate in the first place. One thing to keep in mind (it might be more needed for g-p-m and KDE equivalent) : users might think they laptop are really "off" (harddisk not running) and moving it in a backpack or whatever and the "hibernate part" could be started while laptop is not a "physicaly" stable position. Maybe g-p-m / kpowersave should warn users the first time they enable "hybrid" suspend (with explanation on the timeout)..

It is not an issue for g-p-m right now because it does not expose
hybrid suspend at all. I do not know if kpowersave does - I have not
used kde since the mid 1990's.
