From f146dc06ce32df9c2f9b46691e968c7e1bcaeb52 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 19 Oct 2018 13:44:43 +0100 Subject: [PATCH xf86-video-intel] sna: Only generate a coldprobe RR probe when RandR is enabled MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If Xinerama is enabled, RandR is disabled and calling into RR functions merely explode, so don't.
