>From c9541bb35389c3ccd96a49e9f30509e5bebae760 Mon Sep 17 00:00:00 2001 From: Lee, Chun-Yi Date: Fri, 1 Oct 2010 16:28:29 +0800 Subject: [PATCH] DMI to disable Vista compatibility on MSI GX723 Notebook The brightness control hotkey don't work with Vista compatibility , because MSI GX723 included a infinite while loop in DSDT when brightness control hotkey pressed. MSI GX723 used Nvidia video card, the infinite while loop must be a workaround with Nvidia's Vista driver. This patch should be reverted once nouveau grows support to call NVIF method in DSDT.
