Bug Description
Hello,
For quite some time I've been experiencing problems with Ubuntu after resume from suspend. I have an Asus M70SR notebook with ATI Radeon Mobility HD3470 and using the open-source driver for it (from Quantal official repository). Currently I have Ubuntu 12.10 installed, but the same was happening before with 12.04. It doesn't matter if I use Unity, Gnome-Shell or Gnome Classic - the slow down is always there. My /etc/X11/xorg-conf looks like this:
Section "Device"
Identifier "ATI Radeon 3470HD"
Driver "ati"
Option "AccelMethod" "EXA"
Option "AccelDFS" "true"
Option "EnablePageFlip" "true"
Option "SwapbuffersWait" "off"
Option "ColorTiling" "on"
Option "ColorTiling2D" "on"
EndSection
To give you some picture about it:
Glxgears BEFORE suspend:

ATTENTION: option value of option vblank_mode ignored.
4007 frames in 5.0 seconds = 801.315 FPS
3867 frames in 5.0 seconds = 773.359 FPS
3918 frames in 5.0 seconds = 782.475 FPS
3879 frames in 5.0 seconds = 774.902 FPS
3859 frames in 5.0 seconds = 771.025 FPS

553 frames in 5.0 seconds = 110.366 FPS
530 frames in 5.0 seconds = 105.835 FPS
As you can see the performance after resume from suspend is about 1/8th of the normal. The workaround is to kill the X server (Ctrl-Alt-
As you can see, I use vblank_mode=0 option and in Compiz the Vsync is turned off. The measuring was done from Gnome Classic session, but I can experience the same slowdown in Unity and in Gnome Shell as well.
