jac-tict Posted August 23, 2012 Share Posted August 23, 2012 Hi guys, on MacOSX with DSDT patched by macinsane B570 doesn't reach the minimum brightness. I'm trying to look deeper, hope someone would help. In Linux: xrandr --prop | grep BACKLIGHT BACKLIGHT: 16 (0x00000010) range: (0,976) sudo sh -c 'echo 16 > /sys/class/backlight/intel_backlight/brightness' Gives the minimum brightness. Hero DSDT: Scope (_SB) { Device (PNLF) { Name (_HID, EisaId ("APP0002")) Name (_CID, "backlight") Name (_UID, 0x0A) Name (_STA, 0x0B) } Maybe the problem is that macosx use 10 steps and actual driver has different granularity/lowest values?

Isopropylique Posted September 19, 2012 Share Posted September 19, 2012 I've found that my B570's minimum brightness is actually "off". If I press Fn + Insert enough times, the display can actually be turned off. The maximum is reached with Fn + Home about 3/4 of the way across the on-screen brightness indicator.
