Debian Dual Monitors issue after installing Nvidia newer Driver

Please, help me with this problem.

I'm a newbie in the Linux world. Recently I decided to install Debian 12 Bookwarm and discovered all the challenges involving its integrations with Nnvidia drivers.

My setup consists of an RTX 3070 and an Intel Core i5 13600k. I do have two monitors a Dell 23' and a Pichau Cepheus 29'. When I first installed Debian it came with the Nouveau drivers and both my monitors were working without any problems. I then installed Nvidia proprietary drivers to extract more performance for some use cases. For the first time, I just decided to follow a guide using

Code:

apt
to download the drivers and all their dependencies. It worked pretty well. I was using an HDMI port on the GPU connected to my Dell 23' and the Motherboard HDMI connected to the other monitor. Using the onboard processor graphics.

My problem started when I needed to update the graphics version once the apt version was 345 and I needed the 555 version of the Nvidia driver. I discovered I needed to use the

Code:

.run
installer provided by Nvidia. My process was basically:

1. Uninstall the already installed Nvidia driver.
2. blacklist the Nouveau driver on kernel instruction options.
3. reboot the system in level 2 ( terminal only ). and then
4. Install the driver using the downloaded script.

After the installation, the monitor connected to the motherboard HDMI ¨does not work¨. Curiously the second monitor is on but blank. When I hit

Code:

ctrl + alt + f3
to go to the terminal outside of Gnome it shows the terminal on the other monitor.

Code:

lspci | grep VGA 
output:

Code:

I'm a newbie on Linux. If it's are any commands necessary to better understand the problem please tell me and let me add them.

Thanks for the help!
