Bug Description
RTD3 is a nvidia GPU feature to support runtime suspend.
On-demand would be a X offloading feature.
They are independent, according to discussion on https:/
Some parts need to be adjusted, e.g.
```
# If we are dealing with NVIDIA PRIME, and runtimepm
# is supported, enable it
if (os.path.
try:
except:
pass
# Create the override file for gpu-manager
with open('/
```

[Impact]
* Ubuntu will set GPU mode to performance as default which may use more power
* User can't use GPU for other purpose (eg: deep-learning) if RTD3 is not supported
* According to Nvidia README, the RTD3 doesn't support on non-laptop machine
[Test Plan]
* Install Ubuntu, and then execute 'ubuntu-drivers install' to install GPU driver. After the installation, reboot the system. Execute "prime-select query" should get "on-demand"
* Old GPU (which supported by nvidia-390 only) will keep in performance mode, refer LP:1957094. Execute "prime-select query" should get "nvidia"
* On non-laptop machine. Can set GPU mode to on-demand
* On laptop with GPU in runtime PM support list. Set GPU mode to on-demand and Nvidia driver is loaded with "NVreg_
[Where problems could occur]
* With GPU supported RTD3 not able enable runtime PM on non-laptop. But based on the Nvidia README, this case shall not happened.
