backlight stays off

["David Berg" <drberg1000@gmail.com>]

I have a Linux Certified laptop (LC2210D) and finally decided I'd
rather have both my systems on debian sarge instead of a sarge and an
ubuntu.  So I'm working through getting all the hardware that was
working fine under ubuntu setup under debian.

My current problem is the backlight.  Running `xset dpms force off`
works just fine and the system wakes up with no problem.  The problem
is with a lid event the backlight goes off (though the screen doesn't
blank) and I haven't been able to get it to come back on with out
rebooting.  This happens whether the acpi script is empty or contains
the `xset dpms force off` command.

I haven't been able to find anything in /usr/share/doc and googling
for the terms "backlight linux" didn't seem to produce anything
relevant.

Can anyone give me a hint on where to look for the information I need?

Thanks in advance.
