Default Re: Linux backlight driver

You have to edit the file "/usr/src/nvidia_bl-0.52/nvidia_bl.c", find the "static struct driver_data nv5x_driver_data" section and change .min and .max values. Then rebuild the module. With the latest nvidia driver I had to change .min to 1024 and .max to 133000 for a vaio vpccw1s1e with gt230m. You can try different values, but be carefull because if you change .min to a very low value the screen might turn off completely.
