Since I didn't know about the new zaurusd I hacked up my zaurus-hinge script the other day to provide this funcionality.
Here are the parts I changed:
if [ $STATE = "3" ]; then
echo 0 > /sys/class/backlight/corgi-bl/brightness
fi
and at the top of the "landscape" section (under "if [ $STATE = "0" ]; then" )
I added:
echo 30 > /sys/class/backlight/corgi-bl/brightness
Brightness is 0 (off) to 47 (full bright). Poke around at the other files in /sys/class/backlight/corgi-bl/ to find fun stuff like max_brightness, etc. Anyways, this little hack should get you by until the new zaurusd comes out.
BTW, if you close the Zaurus, then suspend it, then open it, then resume it (in that order), you'll end up with the Zaurus resumed with the backlight off. In that case close the lid, wait a couple seconds and re-open it to make the backlight come on again. You might find other problems with the way I did this since it was just a quick hack to let me listen to music on the go rather than a real fix.
