<pre>Well, the UI has to know somehow at what value the screen is still lit: is that
1 or 0? It is very bad for UX to turn off the screen completely.
Can you explain where the bug is, then? Certainly not in the UI, it only talks
to an abstracted backlight API.
The kernel API here is not consistent (0 can mean both off and the lowest lit
value), and the kernel people don't seem willing to fix this (for fear of
breaking ABI compatibility):

Where would the bug otherwise be, if not here?</pre>
