From d0c2ce16bec0afa6013b4c5220ca4c9c67210215 Mon Sep 17 00:00:00 2001 From: Lan Tianyu Date: Fri, 30 Nov 2012 13:02:50 +0100 Subject: [PATCH] ACPI / video: Add "Asus UL30VT" to ACPI video detect blacklist The ACPI video driver can't control backlight correctly on Asus UL30VT. Vendor driver (asus-laptop) can work. This patch is to add "Asus UL30VT" to ACPI video detect blacklist in order to use asus-laptop for video control on the "Asus UL30VT" rather than ACPI video driver.
