Hello,
I've been able to set a specific brightness intensity at evry boot, by using an /etc/init.d/after.local script, but anytime my system awakes from suspended mode, the brightness resets to a very high intensity.
from dmesg I see:
[ 3.128757] i915 0000:00:02.0: [drm] Skipping intel_backlight registration [ 33.797331] ideapad_acpi VPC2004:00: Keyboard backlight control not available [28383.336476] video LNXVIDEO:00: Restoring backlight state
Hmm ... I actually wonder why ACPI is used for brightness at all. Default should be to prefer native (intel_backlight in this case) unless overridden by system-specific quirks or manually. Can you provide full dmesg output?
