I had to patch manually, for some reason the diff was rejected, but I t
compiled and I've instead on 10/stable... problem is this is the laptop
where I am typing this :D
Its also upgrading some ports, so not a good time to reboot, but I'll post
results in the other thread, as for the HP, works perfect (for me at
least... far better then what I had :) )
% intel_backlight 50
current backlight value: 100% (4882/4882)
set backlight to 50% (2441/4882)
% sysctl -a | grep backlig
hw.dri.0.i915_backlight: 50
% kldstat |grep acpi
9 1 0xffffffff81fb1000 8708 acpi_video.ko
% sudo sysctl hw.dri.0.i915_backlight=100
hw.dri.0.i915_backlight: 50 -> 100
% intel_backlight
current backlight value: 100% (4882/4882
