This should fix the compiz issues across vt switch (works for me). From 087e40e095de737d948f26bb1c28bba34a274fdb Mon Sep 17 00:00:00 2001 From: Keith Packard <[EMAIL PROTECTED]> Date: Tue, 18 Nov 2008 09:30:25 -0800 Subject: [PATCH] [drm] Move drm vblank initialization/cleanup to driver load/unload
drm vblank initialization keeps track of the changes in driver-supplied
frame counts across vt switch and mode setting, but only if you let it by
not tearing down the drm vblank structure.
