Interesting, I hadn't considered that. Might explain something which did confuse me a little. I ran 'free -m' just before hibernating, and from that concluded I had ~280M of ram in active use, minus the file cache etc. Hibernating then wrote ~380M. I have 128M video card so that might explain the difference ? Chris
