From ffa6bdfb74bdfecf1a7faac06502ae1fd1d15548 Mon Sep 17 00:00:00 2001 From: Scott Murray Date: Mon, 30 Nov 2020 19:09:37 -0500 Subject: [PATCH] meta-agl-profile-graphical: backport weston drm tear-down fix As part of the fixes for compositor start up failures on UpSquared, backport the fix for cleaning up the DRM backend when start up fails. This does result in start up working on the UpSquared, but usually after one or more failures, so a systemd dependency to avoid that will also be added via another change. However, this particular fix still seems worth applying as it may be potentially useful for AGL members that roll their own customized distributions.
