[Q] Backlight settings for CM7 - Atrix 4G Q&A, Help & Troubleshooting

Has anyone played with the backlight settings for the Atrix on CM7 pre4 yet? I'm looking to set the brightness down some as it seems too bright to me, but I'm looking for a starting point if someone has one.
Thanks.

i personally use auto brightness, it works great for me... BUT, you might be interested in this thread here, since it allows you to modify the brightness beyond factory settings (maybe even beyond CM7 settings!)

Yea I'm using the auto brightness as well but you can set the levels for the auto brightness to be custom. I'm finding the auto brightness to be too bright in most cases so I want to turn it down.

Keying off the link above, I wrote this "noob" script to toggle LCD backlight level from my home screen with a Script Manager widget. It's basically one touch to toggle and another to exit.
#!/bin/sh
# Toggle LCD backlight setting
cd /sys/bus/i2c/drivers/lm3532/0-0038/leds/lcd-backlight
#First show brightness level
echo Brightness= `more brightness 2>&1`
if [ -f /usr/local/sbin/lowlight.txt ]
then
LEVEL=`cat /usr/local/sbin/lowlight.txt`
else
echo 17 1F > /usr/local/sbin/lowlight.txt
fi
if [ "$LEVEL" = "17 00" ]
then
echo "Setting backlight high..."
echo 17 1F > registers
grep CTRL_A_FS_CURR_REG registers 2>&1
echo 17 1F > /usr/local/sbin/lowlight.txt
elif [ "$LEVEL" = "17 1F" ]
then
echo "Setting backlight low..."
echo 17 00 > registers
grep CTRL_A_FS_CURR_REG registers 2>&1
echo 17 00 > /usr/local/sbin/lowlight.txt
fi
