From 6703a7c7cf1a349c137e247a0c8eb462ff7b07be Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Tue, 8 Jan 2013 20:24:32 -0800 Subject: hw/xfree86: Require only one working CRTC to start the server. Instead of requiring every mode set to complete successfully, start up as long as at least one CRTC is working. This avoids failures when one or more CRTCs can't start due to mode setting conflicts.
