thanks, this seems to work, but after entering suspending the system, it comes back immediately.  In syslog I see that
one device can't suspend ('could not suspend device ...), which is my ehci usb controller.

do you happen to know how to solve this? (in windows the whole system suspends fine...)

(and by the way, can you explain this /sys/power/state way of doing it, isn't apm -S the 'normal' way, or am I
misinformed?)
