From 30aa59759ae9a3629c5f4e6a1d9532c41620328b Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Wed, 2 May 2018 10:21:56 +0200 Subject: [PATCH] desktop-shell: handle NULL output in center_on_output() This is a tentative crash fix for a case where there are no enabled weston_outputs at all. If no output is given, just put the surface at 0,0. At least it should become mostly visible if an output is plugged in, if not centered.
