Bug#738945: [Pkg-xfce-devel] Bug#738945: task-xfce-desktop: Hibernate doesn't work out of the box

[Max Kubierschky <max@knirz.de>]

Hi everybody,

Ok, I was't informed, that hibernating should work without uswsusp.
So I removed uswsusp again, for bug-hunting. I did try as suggested:

- logout button, then hibernate
- pm-hibernate (as root)
- echo disk > /sys/power/state (as root)

All of the above have the same effect: The screen goes black,
after some seconds, the computer switches off. When switching
it on again, It boots normally instead of returning to the hibernated
state.

So this bug is indeed not related to Xfce.

For me personally, the problem is solved, as I am fine with uswsusp.
But if it may benefit other users, I'm willing to cooperate in hunting 
it down further.

As to my hardware: Its a Dell inspiron 1525 Notebook.
To provide more information, below is the output from lspci.
I have the non-free module iwl3945 installed for wifi, but

  rmmod iwl3945 iwl_legacy mac80211 cfg80211

before hibernating doesn't change anything.

Yours, Max
