+Subject: [PATCH] xfree86: allow fallback to PCI bus probe for graphics devices
+ on non-seat0 X servers (#66851)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Currently non-seat0 X servers only probe platform bus for graphics devices,
+which is OK for most KMS-compliant drivers. However, for non-KMS drivers
+(like NVIDIA proprietary ones), graphics devices can't be reached
+by platform bus probe, resulting in a "No devices detected" error.
+
+This patch allows a fallback to PCI bus probe for non-seat0 X servers
+in case no platform bus graphics device is found.
+
