No need to do so. In AT times, before ATX was common, there was no way to power off the machine as it had a mechanical power switch (a _real_ switch), so using -h was the way to go. > >For example, I've programmed Ctrl+Alt+Moon on my Sun USB keyboard... > > Sun keyboards have moon keys?? The moon key is on the top right, and only present on the type 6 and 7 keyboards. Pervious models had a (I) key (power key) in that location. http://stuartconnections.com/products/Computers/Peripherals/Keyboard_and_Mouse_Combos/Sun_320-1366-03/DSC09864w.jpg http://i.stack.imgur.com/D8RsW.jpg http://www.lemis.com/grog/Photos/20120509/big/Keyboard-1.jpeg For comparison: http://imageshack.us/scaled/landing/387/suntype5cks2.jpg http://docs.oracle.com/cd/E19683-01/806-4743/images/keyboard_a.tif.gif The original function of the (I) power key has been to switch the computer on and off. Today I'm using it for session logout, and for power off (with Ctrl and Alt, just to reduce the change of accidental system shutdown). > (I hope and trust that I'm not the only one who finds this fact rather > comical. Perhaps that's why Sun put the key there (?)) Now that Sun doesn't exist anymore, there's the word "Oracle" on top of the keyboard. The moon is more associated with the uncertainity of a mysterious oracle than the sun. :-) > >In the past, this kind of operation has been performed via APM. > >When APM has been fully supported, it was abolished and replaced > >by ACPI.

I cannot wait to participate in this wonderful experience that keeps the "throw away society" alive (and enable us to buy cheaper and more powerful stuff, on the other hand). How will I be going to have a video feed from a VCR when I cannot plug in my fully working and excellently supported PCI TV card (with video input) anywhere? It's hard to keep doing "the same" over the period of time the equipment will work. Okay, no problem if you need to to "something new" (which requires more power, more storage or faster speed), but if that's not the case, the wheel keeps being reinvented. What has been old will be new, except it comes in shiny new marketing mumbo-jumbo to convince us. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
