Comment 11 for bug 510004

I doubt that this problem is related to the nvidia driver. I tested a suspend from the virtual terminal (stopped X and unloaded the nvidia module) - after resume, the monitor is black with some white rectangles but switches to standby soon. Switching to a vt with ctrl-alt-f* does not work. Rebooting the system with ctrl-alt-del works, though.

I have this problem on my desktop and notebook computer - both have a nvidia card (but different ones). So maybe it is hardware related, but not the the nvidia-binary driver itself. Suspend/resume worked on both system without any problems in the last couple of Ubuntu releases.
