AFAIK, only acpiconf calls the rc.suspend and rc.resume scripts (please correct me if I am wrong!), so the above method only really works if you use acpiconf to suspend and the power switch to resume. I find it mostly works using acpiconf -s 1 to suspend, and then closing the lid. It resumes on lid switch open, but does not run rc.resume. I have also tried calling scripts from devd to process the lid switch events, however the rc.suspend scripts does not get called until after resume (and it seems after rc.resume!). I have not tried it yet, but it should be possible to call just rc.resume from devd for the lid switch open event only. Jameshome | help
