Some interesting info here: https://bugs.launchpad.net/ubuntu/+s...on/+bug/583525 and here: https://bugs.launchpad.net/ubuntu/+s...er/+bug/738526. Do you have xfs installed?
apt-cache policy xfs
I believe this is a bug. If you look in your /var/log/Xorg.0.log file, it should show you which driver is being loaded and it should say nvidia.
I did select the nvidia proprietary drivers. The Ubuntu "additional drivers" tool shows:
NVIDIA accelerated graphics driver (version 173): This driver is not activated.
NVIDIA accelerated graphics driver (version current) [Recommended]: This driver is activated but not currently in use.
1. Have you fully updated the system?
2. What modules are loaded:
3. Try suspending manually from the command line to see if it produces a different result:
4. Try disabling Compiz and then suspending. Any change?
