sleeping and xfce4 on thinkpad T21

Hi!

I've just got an older IBM ThinkPad T21. Suspend to disk and suspend to RAM works more or less (see other mail), when I just do an 'echo "mem"
> /sys/power/state'. But when using xfce as Desktop Environment, I
encountered a small Problem when setting it to sleep.

The core of my problem is, that alsa has some problems, when setting the notebook to sleep (be it suspend to disc or to ram). When I wakeup my notebook, alsa is more or less dead.

Therefore I set in /etc/default/alsa
"force_unload_modules_before_suspend" to all. And if I now run "/etc/init.d/alsa suspend" before doing the 'echo "mem" > /sys/power/state' it seems to work.

However: The "/etc/init.d/alsa suspend" kills processes using alsa, which includes xfce-mcs-manager. No big Problem, I can start that again after resuming my notebook, but isn't there a better solution?

And is there a possibility, so that I don't need to be root (or use sudo) to send the notebook to sleep?

Yours sincerely,
Alexander
