Hi Jani,

Yes I still have the issue. The minimum brightness available on my display
simply hurt my eyes and without this patch I cant use my laptop. Even if you
say that its going to damage the hardware, I would still insist, because I'd
rather have my hardware fail first, than my eyes.

I need a way to force at the brightness to go down at least 10% of the max
brightness. My safe level is 'echo 100 >
/sys/class/backlight/intel_backlight/brightness' which works only if I have the
attached patch that allows to override the min brightness value from VBT. I use
the value "-1" for the min_brightness module parameter. Please see the attached
patch.
