Re: When the monitor does not wake up from the sleep mode
JavaBeanHead: As is the case with almost any nVidia card under Ubuntu these days, drivers for yours can be enabled (read: automatically detect correct version, then download & install it) under System > Administration > Hardware Drivers.
Enable the recommended one if given multiple choices, provide your password when prompted, it'll apply all changes, and then a reboot will be necessary. That's all there is to it.
