From 6d3759fac636028849f3bbec80c4b77e9bfdb1d2 Mon Sep 17 00:00:00 2001 From: Michel Dänzer Date: Fri, 21 Nov 2014 11:48:57 +0900 Subject: drm/radeon: Re-show the cursor after a modeset MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Setting a mode seems to clear the cursor registers, so we need to re-program them to make sure the cursor is visible.
