please inform us, what does "xset dpms force off" do? And for what circumstances/purpose do you use it?
Sorry it took so long, I missed your reply.
"xset dpms force off" is supposed to turn off the screen immediately using DPMS, at least thats what it seems to do. I just don't want to suspend (suspend the whole system to RAM) everytime I close the lid, rather I like it to continue to work on whatever I told it to do :-)
That _is_ the default behaviour - the laptop should do nothing at all when the lid is closed. I know of no particular hardware/BIOS that sets a sleep action upon lid closure. It is only altered by userspace tools/daemons like for eg. when using a DE. You might want to check what else is enforcing a rule to the lid-closing state.
Mine does turn off the backlight, and I'm quite sure there's no userspace involved, just plain hardware/bios. No idea whether others do more than that. Turning off the backlight seems like reasonably safe thing to do.
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
