I have a Dell Inspiron 9400. When it used F6 it "noticed" the lid switch, and did suspend. With F7 nothing happens. Also when I experiment with pm-suspend and various "quirk" parameters, I always get to a blank screen except for this message: stopping tasks ..... done Suspending console(s) I note that various sub-directories of /etc/pm/ have no files. I don't know what to do from here. Perhaps someone could guide me. Thanks DP South Australia
