ACPI: edit lid.sh to blank screen, turn backlight off, no-suspend ?????

Outabux · 10-04-2004, 02:31 PM

Debian Linux, SID

2.6.8-7 w/ dsdt-initrd, debianlogo patches No suspend enabled in kernel, NVIDIA 5336 or 6111 depending, currently 5336 (GeForce 4 440Go)

Inspiron 8200 w/ Precision M50 A12 BIOS (C/Dock II functionallity)

ACPI components compiled as modules (no fan, that is done by BIOS; I use i8k module and gkrellm & i8k plugin for that)

How do I configure ACPI (lid.sh) to blank the screen and turn off backlight upon LID CLOSE and reenergize upon open?
I have KDE do this after five minutes without user interaction.

Would like to perform this action of blanking screen/backlight off during non-X as well.

Please include code and a place of a good direction to start.

Again, nVidia!

Thanks in advance

Turning the graphic card off (ACPI) ( post #1)

I've been trying to put my nVidia GForce 2 card to sleep. Before booting Linux, my computer turns the display off after 1 minute (I can tell that turns of the graphic card because the power consumption - monitor excluded - drops by 25 watts)! I could not get the computer to turn the display off in linux, is there a way to enable that so Linux can listen to my ACPI BIOS?
I have kernel 2.6.6 with ACPI support (it does work) and I am using the latest nvidia driver that has ACPI support (I also tried switching from agpgart to nvagp but it didn't help).

ANOTHER POSSIBLE SOUTION, would be to turn the graphic card off through linux. The only way I know how to turn the display off is using KDE Display Power Management but that only turns of the monitor not the graphic card.

I'd really appriciate any help, specially since I've wasted more power than one year of turning display off by compiling the kernel so many time!!!

download and install acpid. Here is a mini-howto that shows a command being executed on the button/power event. The lid would be a button/lid event. There is a little more to it that I'm still figureing out, but you would also need a command that would blank the screen and turn off the backlight.

Um, that is what im looking for...w/nvidia video card

Thanx!

ok, I think i've got it figured out now. My default acpi event handler looks liek this:

Code:

case "$group" in
    button)
	case "$action" in
	    power)	/sbin/init 0
		;;
	    lid)	
		case `cat /proc/acpi/button/lid/LID/state | awk '{print $2}'` in
		    open)	/usr/X11R6/bin/xset -display :0 dpms force on
			;;
		    closed)	/usr/X11R6/bin/xset -display :0 dpms force off
			;;
		esac
		;;
	    sleep)      echo 1 >/proc/acpi/sleep
		;;
	    *)	logger "ACPI action $action is not defined"
		;;
	esac
	;;
    
    *)
	logger "ACPI group $group / action $action is not defined"
	;;
esac

To get xset to work for the acpi daemon, you have to give root permission to use the X display. you can do this by running a command like this:

Code:

 xhost +local:root

the sleep button still doesn't do what it's supposed to do (it starts to sleep, and then comes back), but the backlight turns off alright.

also, the following needs to be in the Monitors section of your x config:

Code:

Option "DPMS"

provided your X is propery configured and your screen supports is, just use "xset dpms force off" to switch off the display, and "xset dpms force on" to switch it back on
