Screen won't dim

Reasons · 2008-01-19 23:03:23

On another (third laptop I've put arch on) computer, the screen won't dim automatically. It's using gnome and when I unplug the power cord, the OSD comes up showing a lower value but the screen stays the same.

I guess the problem would be that it isn't giving the correct command so where would the script, or whatever manages gnome-power-manager, be so I can edit it. I already tried gconf-editor.

If you have a ATI gfx, perhaps it works also with Nvidia, it could help to unload the video module [modprobe -r video] or put it in the 'Blacklist Modules' in the rc.conf. Hope it helps

Intel X3100.

Still safe to try? I mean, I could just modprobe video if it breaks, right?

EDIT - tried it, no luck. Xbacklight -dec 10 works though. That's what I don't get.

I've got it somewhat going now using acpid. I'm just not sure which to use under battery and A/C and which of those to use. Right now, it dims when unplugged but nothing when I replug. Actually, all it does is dim, when there is a switch.

[#!/bin/sh
# Default acpi script that takes an entry for all actions

# NOTE: This is a 2.6-centric script.  If you use 2.4.x, you'll have to
#       modify it to not use /sys

minspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq`
maxspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq`
setspeed="/sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed"

set $*

Fixed. Used /etc/acpi/handler.sh to start and stop laptop mode and have laptop mode control the backlight. Oddly enough that didn't work earlier. . .

Can you please post you /etc/acpi/handler.sh ?
