Xorg freeze after hibernate restore with nouveau driver

[blackpaw]

I have Sleep and Hibernate working perfectly with the nvidia drivers.

However with nouveau:

- Sleep works fine.

- After a restore from hibernate xorg displays and freezes. However I can switch to a text console, restart lightdm and get a working X again

The problem goes away if I disable OpenGL in Desktop effects, so presumably its related to that.

Any suggestions?

Thanks - Lindsay
