This patch exposes the backlight support via a sysctl: set the backlight to 10%: # sysctl hw.dri.0.i915_backlight=10 hw.dri.0.i915_backlight: 25 -> 10 set the backlight to 50%: # sysctl hw.dri.0.i915_backlight=50 hw.dri.0.i915_backlight: 10 -> 50 decrease the current backlight value: # sysctl hw.dri.0.i915_backlight=-1000 hw.dri.0.i915_backlight: 50 -> 43 increment the current backlight value: # sysctl hw.dri.0.i915_backlight=1000 hw.dri.0.i915_backlight: 43 -> 51 # sysctl hw.dri.0.i915_backlight=1000 hw.dri.0.i915_backlight: 51 -> 60 I am running this path on for about a week without issue. This path can be found at: https://github.com/maurizio-emmex/i915_backlight_freebsd I thank Elizabeth Myers, elizabeth at interlinked dot me, for the idea of adding the backlight support for the i915 driver and for the original patch.
