I'm using a Sony Vaio Z. (VPCZ122GX to be precise) I have to use a modded kernel to boot and then reboot into the new kernel in order to get accelerated graphics. This is due to the nature of the hardware graphics chip switcher. I've got the NVIDIA graphics working fine, except for suspend/hibernate. When I suspend it goes to sleep, however, when I open the lid and press the power button, the light comes back on, but I have nothing on my screen. Its just black. I can't even enter tty1. I'd appreciate any possible solutions to my problem.
