[SOLVED] What is the "proper" way to disable acpi from grabbing the xf86power in X sessions.

Old_Fogie · 01-20-2012, 07:59 PM

Hello all,

Was wondering if there was a way to modify the acpi scripts such that the acpi daemon does grab the xf86 power button from a run level 3 with no X session running ; but if a user is logged into XFCE or KDE run level 4 then acpi ignores the power button press and allows the desktop environment's power management to manage the power button keypress.

Any ideas?

Sorry to see you suffering with zero replies. I found a couple of threads with maybe some bits of relevance:

It seems to me that you need to add some code in rc.4 which will disable the power button keycodes when starting X, using xbindkeys or xmodmap. Or maybe it would be better to figure out how to do that in xorg.conf or a fragment in xorg.conf.d

Hope this helps you a bit. I know you're an old pro (as well as fogie), so I won't try to hold your hand...

Thanks gnashley for your help, I'm making progress on this, but it's not post ready yet. /fingers-crossed

Hi, you could check if /var/run/kdm.pid exists in your /etc/acpi/acpi_handler.sh and react from there.

Hi again,
here is what I'm using now:

/etc/acpi/acpi_handler.sh

Code:

#!/bin/sh
user=$(who|grep " :0 "|cut -d" " -f1)
case "$1" in
  "button/power")
    if [ ! "$user" ];then
        /sbin/poweroff
    fi
    ;;
  *)
    logger "ACPI group $1 / action $2 is not defined"
    ;;
esac

edit: the format goes away

NeoMetal thank you!

Use [?code][/code?] tags instead of quote to keep code formatting. - the '?'s of course

Fantastic! This indeed does work. I've been using it daily for a week now, and it has been flawless.

Thank you!
