Hi, on my UX31A it is/was like this: - after 277959 the display was dark - backing out 277959 gave full brightness, but no brightness control using hw.acpi.video.lcd0.brightness anymore - after some more syncing with Linux 3.5.7, brightness control using hw.acpi.video.lcd0.brightness works again - brightness control using the function keys (acpi_asus_wmi?) never really worked, neither before nor after the changes to drm2/i915.
