Yes, what I meant to say was that most laptop BIOS's switch off the monitor by default, so you shouldn't need to do any fiddling around other than when a possible power management tool has interrupted this behaviour. Except for very old models that do not recognise lid closure as an ACPI event. -- GPG/PGP ID: B42DDCAD
