From 25c7e52ada781a5165370b0c4558560466f60a71 Mon Sep 17 00:00:00 2001 From: Ray Strode Date: Thu, 12 Apr 2018 14:06:01 -0400 Subject: [PATCH] xwayland: Don't abort if Xwayland crashes Right now if Xwayland crashes, we crash, too. On some level that makes sense, since we're supposed to control the lifecycle of Xwayland, and by it crashing we've lost that control. But practically speaking, the knock-on crash adds noise to the logs, bug trackers, and retrace servers that only makes debugging harder. And the crash isn't something mutter can "fix", since it's ultimately from a bug in Xwayland anyway. This commit makes mutter exit instead of crash if Xwayland goes away unexpectedly.
