Macbook6-1 (GeForce 9400M)
Ubuntu 12.04
nvidia-current 295.40-0ubuntu1.1
Works perfectly without nvidia driver (nouveau driver).
Attached values of /sys/devices/virtual/backlight.
Write random values to any of that files, didn't destroy the machine neither
did nothing.
Modifications to the default command line arguments to the kernel where
made in grub:
* reboot=pci # To make the computer restart (before, shutdown -r now just
hangs for ever after system shutdown)
* acpi_backlight=vendor (Tested with and without without any change).
** Attachment added: "# find /sys/devices/virtual/backlight/ -type f -exec echo
-n "{}: " \; -exec cat "{}" \;"
