Comment 11 for bug 116826

It looks like gnome-power-manager has two options, one is available as a setting in the menu, the other one is only available in the gconf-editor.In the gnome-power-manager settings dialog, you can set the PC's timeout for initiating hibernate. However, there is also an option in the gconf-editor for gnome-power-manager, that handles the sleep timeout. In my fresh install of Ubuntu, I putt the hibernate function on 11minutes, and the sleep function appears to be sett at 120 seconds.

Probably this is going wrong: after 120 seconds, the PC starts sleep mode. When you start it again after the 11 minutes have elapsed, it somehow makes the error that the 11 minutes should be counted too when the system is at sleepmode and thus hibernating needs to be activated.I now have put hibernation to off, and sleep to 180s, will report later if this seems to be working.

I would like to know from people that also suffer from this bug: Do you have enabled the hibernate timer in the gnome-power-manager settings menu? If so, do you get the same symptoms if you wakeup before the selected hibernation time ?

I really wonder why sleep cannot be configured from the settings menu of gnome-power-manager, and it also really looks like this bug is related to gnome-power-manager, and not a kernel issue.
