I have a Samsung Series 7 Chronos (700Z5C-S02UB) and a couple of kernel updates ago (I'm currently on 3.5.0-25-generic ), I lost the keyboard backlight support.
Any idea on how to turn it back on?
NOTE: I've already had samsung-tools, I've re-installed but still doesn't work
EDIT: I manage to get it working (somehow). What I found is: the ambient light autodetect works, but it seems to be unable to control the level of brightness. If I boot windows and set it to high, it works in Ubuntu (it might be just a coincidence tho)
