From b0e07da3f5c8d069d186a7983ff64eaebf2ea230 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Mon, 11 Sep 2017 11:39:50 +0200 Subject: qxl: fix primary surface handling The atomic conversion of the qxl driver didn't got the primary surface handling completely right. It works in the common simple cases, but fails for example when changing the display resolution using xrandr or in multihead setups. The rules are simple: There is one primary surface. Before defining a new one you have to destroy the old one. This patch makes qxl_primary_atomic_update() destroy the primary surface before defining a new one. It fixes is_primary flag updates. It adds is_primary checks so we don't try to update the primary surface in case it already has the state we want it being in.
