Re: i915kms.ko regression?

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.

Regards, Lutz
