I have just upgraded to Hardy. Switching the display worked with Gutsy (display driver: NVIDIA-Linux-x86_64-1.0-9755), but does not work with Hardy (display driver: NVIDIA-Linux-x86_64-174.55 for CUDA 2.0 BETA). As the same problem exists with the nvidia-glx-new drivers, the driver does not seem to be the reason for the problem.
Confirming.
