From f2da0e2f686ee16ddd3a4e92e06ef3a55ec80472 Mon Sep 17 00:00:00 2001 From: "Miguel A. Vico" Date: Tue, 4 Apr 2017 14:39:47 -0700 Subject: [PATCH 1/9] compositor-drm: Release current & next fb when deactivating the session X-NVConfidentiality: public With commit 47224cc9312fef05c1a523ea0da0a1aae66f100d Author: Daniel Stone Date: Sat Nov 5 08:04:07 2016 +0000 compositor-drm: Delete drm_backend_set_modes we stopped forcing a modeset when restoring the session. The motivation was that we would use a stale fb, so better to let the next repaint handle it. However, if drm_output::current != NULL, we won't issue a modeset upon repaint. This change releases both drm_output::current and drm_output::next when deactivating the current session. This ensures the very first repaint after restoring the session will issue a modeset.
