+Subject: [PATCH] weston: Enabling DRM backend with multiple displays
+
+There are three main issues that this patch tries to address
+
+ 1. Black screen when running weston
+ 2. Support for multiple displays
+ 3. Handling missing VBlanks
+
+There is an issue with missing VBlanks for LCD and
+HDMI connectors which leads to display not getting refreshed.
+This patch can be considered as a workaround.
