+
+  * debian/patches/timeout-for-ping.patch: Raise the ping timeout from 2 to
+    30 seconds. Two seconds was way too short,
+    - causing ping to randomly fail on some busy multi-monitor start-ups,
+    - causing gdm to think no plymouthd is running,
+    - causing gdm to never call 'plymouth deactivate',
+    - causing plymouthd to retain ownership of the graphics hardware,
+    - causing gdm's login screen to fail to start. (LP: #1872159)
