I tested my Idea and it is just working. All I changed is from original
3.0 kernel samsung-laptop.c is the "set_brightness" function. I can't
notice any problems with the fast change to min_brightness. I think this
should work on any Samsung Laptop and doesn't require any complicated
quirk check. Sry I don't have a patch right now but this is the code I
used for testing:
static void set_brightness(u8 user_brightness)
{
if (user_brightness == read_brightness())
return;
u8 user_level = user_brightness + sabi_config->min_brightness;
sabi_set_command(sabi_config->commands.set_brightness,
sabi_config->min_brightness);
sabi_set_command(sabi_config->commands.set_brightness, user_level);
}
This code might be a bad Idea or bad written. I never coded anything
hardware or kernel related. Sry.
