i'm trying to power on the keyboard backlight on my new laptop but every attempt has miserably failed. I've tried to use xset but nothing happens. I've been able to manually set the capslock led on/off but nothing else since i added acpi_osi= in my grub configuration. At least before that i could see the asus_airplane folder under /sys/class/leds and i could set it on/off too (now its gone) but the main backlight of the keyboard seems completely missing (i've seen the folder kbd_backlight referred in many forums).
Any ideas? Is possible the kernel has no clue my keyboard can do that? Thanks a lot, i wish i won't be forced to reinstall windows and virtualize ubuntu again :(
