Amazing! I've been looking for something like this for a long time. This should improve charging times by a landslide! +Karma to you!
EDIT: However, shouldn't it be a .sh file instead of .dge? Or does that matter? I could be wrong as I know next to nothing about Dingux yet.
EDIT(2): Okay, I have an issue with this. I run the script, but it instantly boots be back to GMenu2x. I read the output by repeatedly launching the script, and I got that it said something along the lines of
/bin/sh: /boot/local/gmenu2x/scripts/lcdoff.dge: not found
However, both lcdoff.dge and cpu are in /local/gmenu2x/scripts/. lcdoff.dge contains nothing but the code in the first post of this thread. What am I doing wrong?
