I'm having trouble with hdmi on a hp compaq cq60 with Nvidia Geforce 8200M G. Connecting PC on TV it shows "no signal" but according to xrandr it is connected, using blob (version 304.88) I'm having the same issue but if I use the legacy driver (173.14.36) the problem disappears. Screen disappears as soon as the kms module is loaded. Connecting TV with vga it works with all versions of blob and nouveau. It would be great to be able to use the hdmi without the nvidia drivers. What do you need to help you find a solution?
