My machine is a little weird on the graphics/monitors. I'll go into that in a bit, but I'm specifically looking for how to do the following:
When the monitors are standing by, but the system is running, usually pressing a key on the keyboard will wake them up. Is there a way to accomplish the same kind of waking up from the command line, when remotely connected over the network?
The specifics of what this solves for me is that when I reboot my machine, the nvidia powermizer settings get reset to adaptive. Because this is a managed desktop I cannot edit /etc/ files to change this. I do have something that sets it to maximum performance once I log it. This eliminates the flicker I get on my second display port monitor, and it allows the screens to wake up after being timed out to stand by. So, if I reboot and do not log in, the screens might sleep, and then not wake up. However the machine is still running fine.
If you're curious the driver is nvidia 195.36.24, the card is a Quatro FX 580, the monitors are two Dell U2410 attached via display port (DFP-3 & 4); the VBIOS is 62.94.96.00.05
PS would create tags sleep and powermizer
As much as the answer is correct for my question, it seems that the state of non-waking monitors cannot be gotten out of this way.
