Subject: [PATCH] compositor-drm: Release current & next fb when deactivating
the session
X-NVConfidentiality: public
With
commit 47224cc9312fef05c1a523ea0da0a1aae66f100d
Author: Daniel Stone <daniels@collabora.com>
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.
