From b334f2b3b68c35fd86a0cbc90ecee40e63ba2f37 Mon Sep 17 00:00:00 2001 From: Maarten Maathuis Date: Sun, 9 May 2010 14:49:52 +0200 Subject: [PATCH] drm/nouveau: allow cursor image and position to survive suspend - This isn't triggered yet on a normal kernel, because it still does a VT switch, but it seemed like a good idea to fix this now.
