hyperair, thanks for responding.
As you suggested, I tried using a "fresh" user - but nothing changed. I than found bug #42052, a very old bug, which seems to be still alive in Intrepid - at least for xfce-users. Citing from https://bugs.launchpad.net/ubuntu/+source/gnome-power- manager/+bug/42052 Jarno Suni wrote on 2008-12-16: ... In Xfce4: Additionally choose Power Management in Screensaver preferences and choose a way to suspend/hibernate. You can not use the "Ask me" option in Power Management preferences like above (or you can, but it doesn't lock screen when you resume). Then use that way to suspend/hibernate. In summary: whenever you suspend/hibernate using the Quit dialog, screen will not be locked. So from my point of view this is true. So for the time being adding a script to /etc/pm/sleep.d is at least a solution for a real problem. It works for me and my data is safe now. If you give me further hints how to debug I'd really like to help to find the root cause though !
