Monitors connected to on-board HMDI and VGA ports shows blank after installing Nvidia Driver | Fedora 32

Greetings all.

I am using a desktop with 3 monitors.

2 x 21-inch Dell monitors
1 x 34-inch LG monitor

The 2 Dell monitors, one is connected to the VGA port on-board, and the second one is connected to the onboard HDMI port.

The third and the large monitor 34 inches LG is connected to the HDMI port of NVIDIA GeForce GTX 1650 SUPER.

The system was using Windows 10, but I replaced it with Fedora 32 KDE last week, also installed Nvidia driver and CUDA successfully then. It has been working well until today, but I have no idea what really happened in the system or if some system update has undergone without my knowledge, when I tried to boot up the machine today morning, all I can see only the large 32inch LG monitor connected to Nvidia graphic card is showing up. The system is showing disconnected status for the rest two Dell monitors connected on-board VGA and HDMI ports which are using Intel onboard integrated GPU.

Have you guys faced the same issue?.

What could be wrong here?.

Fixed it myself https://ask.fedoraproject.org/t/monitors-connected-to-on-board-hmdi-and-vga-ports-shows-blank-after-installing-nvidia-driver-fedora-32/9655
