+Subject: [PATCH] vulkaninfo.c: fix segfault when DISPLAY is not set
+
+Both xlib and xcb interfaces expect the DISPLAY environment
+variable to be set before creation of a window and the
+display creation mechanism would segfault if that is
+not the case and won't provide the user with details on
+what has to be done to correct the problem.
+We now handle such scenarios and exit cleanly after
+providing the user with some details.
