From 03d6069912babc07a3da20e715dd6a5dc8f0f867 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Fri, 5 Jun 2009 18:19:56 -0700 Subject: [PATCH] drm/i915: Hook connector to encoder during load detection (fixes tv/vga detect) With the DRM-driven DPMS code, encoders are considered idle unless a connector is hooked to them, so mode setting is skipped. This makes load detection fail as none of the hardware is enabled.
