power button

Hello,

I like that (by default) pressing the power button causes a clean(ish)
system shutdown, but I don't like how easy it is to hit it by
accident. Is is possible to make it so that I have to hold down the
button for a second (or some duration shorter than the BIOS's
hard-reset push-and-hold duration), so I can't kill all my running
programs and shutdown my system by missing the backspace key or
absentmindedly pushing the power button to unsuspend my machine when
it's already on?

Thanks,
Aidan Gauland

In the good ol' days (using the old system v init system), you could
define what happened when it caught that interrupt. Nowadays it's
probably a little simpler... if you can find where to do it. I'd guess
it would have something to do with kdm/gdm - as what happens there
should be different from what happens at terminal.

If you're on GNOME / Ubuntu, goto System -> Preferences -> Power
Management Preferences -> General and choose an appropriate action for
"When the power button is pressed". I've set mine to "Ask Me". This
will popup a box with shutdown/restart/suspend options when you hit
the power button, and will default to 'Shut Down' after 60 seconds.
Other distros should have a similar power management applet with an
option to choose an action upon pressing the power button.

Another alternative is to remap the power button (XF86PowerOff) to
your own command/script: "shutdown -P +1" will wait for one minute
before powering off the machine. You could then map another hotkey to
"shutdown -c" which will abort a shutdown.

Shiv

another good option might be a script that only shuts down if you press the
button twice in some short time.

If you do the "shutdown -P +1" approach, you'll probably also want to
display a message - zenity in gnome does quite nicely. Not sure what
the equivalent in KDE is. Otherwise you might not know to hit that
other hotkey...
