Ah yes, the classic
"Obi-Wan" error.
I tried telling it to set the frontlight brightness to "-1", but no jailbreak resulted from that. Just an error message.
I did not have a room dark enough for visual testing at the time I posted this discovery. It looked "off" to me, and besides, after setting it to zero with lipc-set-prop, reading it back with lipc-get-prop showed that it was indeed zero. Why would kindle software lie to us?
Though it makes sense that its behavior mimics the brightness slider, which is probably just a GUI layer over this very same lipc command.
Whereas the corresponding /sys file is a kernel driver interface, which gives us a closer connection to "bare metal" reality and a greater degree of control (where zero is indeed off, and 999 is max brightness).
