After resume:

/sys/class/backlight/intel_backlight/brightness:426
/sys/class/backlight/intel_backlight/power/control:auto
/sys/class/backlight/intel_backlight/power/async:disabled

/sys/class/backlight/intel_backlight/power/runtime_suspended_time:0
/sys/class/backlight/intel_backlight/bl_power:4
/sys/class/backlight/intel_backlight/max_brightness:851
/sys/class/backlight/intel_backlight/actual_brightness:426
It's purely Xorg by the way; LightDM revives the screen correctly after resume,
but after logging in again, the screen is dimmed completely.</pre>
