From 9412d34e2dc1d8b034e117950ede1424dc0f243c Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Thu, 7 May 2020 12:04:14 +0200 Subject: backend/drm: disable cursor in dealloc_crtc dealloc_crtc was destroying GBM surfaces, but the cursor_enabled flag was left as-is. When re-enabling the output, atomic_crtc_pageflip would try enabling the cursor plane, but would fail because no framebuffer is available.
