commit 731b5a15a3b1474a41c2ca29b4c32b0f21bc852e Author: James Simmons <jsimm...@infradead.org> Date: Thu Oct 29 20:39:07 2009 +0000
drm/kms: properly handle fbdev blanking uses DRM_MODE_DPMS_ON for FB_BLANK_NORMAL, but DRM_MODE_DPMS_ON is actually for turning output on instead of blank. This makes fb blank broken on my T61, it put LVDS on but leave pipe disabled which made screen totally white or caused some 'burning' effect.
