Turn off LCD backlight

I installed SparkyLinux 4.5.2 i686-lxde on my aging laptop last week, and am generally delighted with it. However (there's always a "however") I'd like to know if there is some setting that can turn off the LCD backlight after a timeout. I know that I can do this with an xset command in any of several files, but it would be preferable to use something in the desktop menus if the option exists.


Duh. Suitable options are on the "Advanced" tab of the screensaver.

As per my knowledge you'll need to rebuild the kernel with sysfs and then mount this file system.  If you want to access this directly, without sysfs, you'll need to write some code that changes the state of the GPIO line that handles the backlight.  This is line 4 on gpio bank G, so the call from the kernel would be.
