How to Power-Off with Button?

win32sux · 04-11-2005, 08:42 AM

How can I make it so that when I hit the power button on the case my PC will go through it's regular shutdown sequence (runlevel 0)?

Right now if I hit the power button the PC goes into like a sleep mode or something and I need to hit a key on the keyboard to wake it up. I'd like to change that sleep mode for a shutdown/halt. How can I accomplish this?

BTW, I am using Linux 2.4.29 (APM). Thanks!

Hrm, usually holding down the power button for 3 to 4 seconds will cause it to power off...don't know if it does anything on the system level.

thanks for the reply...

yeah, holding the button down for a few seconds cuts the power abruptly - a very bad thing, as the shutdown scripts aren't run...

i need the system to go into runlevel 0 when the power button is hit (without the need to hold it down)...

i want the effect of hitting the power button to be the same as issuing the "shutdown -h now" command...

That's not going to happen, AFAIK. What it does is causes the hard drives to write out their cache and then shuts everything down in as gentle a state as possible, as compared to say an abrupt power loss. The kernel may or may not interpret this correctly, maybe someone else will know.

The only problems you should see with regards to applications are those that when starting look to see if a pid file is present then refuse to start up b/c it wasn't shut down properly. I don't know of many that do that though.

I run the latest mandriva on a Fujitsu-Siemens Scenic xS. When I push the power button, it logs off properly and does a regular shutdown. However, thhe next time I start, it boots in CLI instead of X.

You need ACPI enabled in kernel and acpid running. Then the powerbutton will trigger an ACPI event, I believe it is shutdown by default.
