[SOLVED] Power button action

qweasd · 06-22-2012, 07:01 PM

I put Slackware on Zareason's Alto and started playing with power options. Trying to make power button to hibernate or bring up menu, but it just ain't happening. Regardless of settings in KDE it seems to instantly run shutdown.

Kind of off-topic, but should I expect all of the Fn- things to work? Brightness and sound level, for example, work great, while sleep and wifi do nothing. Looks like may be half of them work.

I had a similar problem with my netbook. I set up the XFCE power manager to hibernate the netbook when the power-button is pressed. This worked, but when waking up the netbook it shutted of the system after the wake-up finished. This was caused by the settings in /etc/acpi, the power-button was set up to shut down the system there.

Thanks! /etc/acpi was everything I needed.

/etc/acpi/acpi_handler.sh is all you need. Just edit that script and set a different function for "power" under 'case "$2"'.

As for the Fn keys, check to make sure Action Keys, or Function Keys (different names on different motherboards) is set to <Enabled> in your BIOS too.

How should I edit /etc/acpi/acpi_handler.sh so that the system suspends when I press the power button?

I don't know how you could edit /etc/acpi/acpi_handler.sh directly to do that, but you could just comment out everything in /etc/acpi/events/default, and have Xfce (or whatever GUI you use) manage the power button itself (that's what I did and it works just fine).

A while back, I was having trouble with X on my desktop: all mouse/keyboard input was ignored, so there was no way to exit X, not even Ctrl-Alt-F1 to switch to a text console. The only way out was the power button, but that incurred a power-cycle on every iteration of the bug-hunt.

The quick & dirty solution:

1. In /etc/acpi/acpi_handler.sh, change the "power" case to execute "/sbin/init 3".
2. "telinit 4" to launch X, powerbutton to kill X. No power cycle, plus it's just a whole lot faster.

I know that this is an old post, but this is an useful question since the /etc/acpi/acpi_handler.sh file is always replaced when Slackware is reinstalled or in new installations.

The best solution I've found here was to do what TommyC7 said, but replacing

Code:

power) /sbin/init 0

simply by

Code:

power)

In this way, when pressing the power button on the keyboard the logout screen appears (with the options to turn off, sleep, restart, etc...) instead of turn of the PC instantly.

If you don't have a use case for acpid, you can just disable it:

Code:

/etc/rc.d/rc.acpid stop
chmod -x /etc/rc.d/rc.acpid
