ASUS ROG with RTX 3060 (ubuntu 18.04) Screen Blank


I have Asus ROG (Intel i9) with Geforce RTX 3060 running Ubuntu 18.04. I also have nvidia 460 (460.84-0ubuntu0.18.04.1) installed.

The nvidia-smi generates valid output.
NVIDIA-SMI 460.84 Driver Version: 460.84 CUDA Version: 11.2

But for some reason the laptop monitor continues to stay blank. External monitor works fine. If I disconnect the external monitor, the laptop continues to stay in blank screen. It seems to have difficulty loading the X-windows on the laptop.

I would really appreciate any support to help me fix this issue or any other materials that solves this problem. So far searching the forum I have not found useful links that fixes this issue.

Attached the output from nvidia debugger.
