Re: [gentoo-user] Laptop Lid Close...

[Gregory SACRE <gregory.sacre@gmail.com>]

This is the script I am using. It is spawned by the default.sh from /etc/acpi:

-------------------------- SCRIPT START --------------------------
# default display on current host
export XAUTHORITY="/home/<your_user>/.Xauthority"
DISPLAY=:0.0

# find out if monitor is on
STATUS=`cat /proc/acpi/button/lid/LID0/state`
logger "monitor: $STATUS"

# find out if DPMS is enabled
DPMS=`xset -display $DISPLAY -q | grep -e 'DPMS is'`
logger "dpms: $DPMS"

# enable DPMS if disabled
if [ "$DPMS" == "  DPMS is Disabled" ]
then
        logger "Enabling DPMS ..."
        xset -display $DISPLAY +dpms
fi

if [ `echo $STATUS | grep -i closed | wc -l` -eq 1 ]
then
        logger "[`date`] Turning display OFF"
        xset -display $DISPLAY dpms force off
else
        logger "[`date`] Turning display ON"              # shows up in log
        xset -display $DISPLAY dpms force on            # turn monitor on
        xset -display $DISPLAY s activate               # un-blank monitor
fi

#clean up
unset STATUS
unset DPMS

# comment this line out if you're manually running this script from a
shell (put a # in front of it)
unset DISPLAY

exit 0
-------------------------- SCRIPT STOP --------------------------

Change the <your_user> variable.
I had also to set xscreensaver to switch off my monitor instead of
blanking it, because I think (not sure) that xscreensaver was
switching on my monitor when it was supposed to start the screensaver
(as after a while, my monitor was switched back on, and as I didn't
see that happening since my xscreensaver modification, I can only
assume that was the problem).


HTH,

Greg

I can toggle the button with the lid open and cat /etc/acpi/button/lid/LID/state and see it change between 'open' and 'closed'; and I know I could write myself a little script do something like calling radeontool to turn off the backlight, but I'd like to find a more official method.

The only thing I can find is a the standby/suspend/shutdown/logoff, system performance, and CPU throttling. I don't really want to do any of that - just put the monitor into stand-by, not necessarily the whole system.
