Hello,

After installing nvidia drivers using nvidia-installer-dkms my monitor which is plugged into my graphics card does work. However, I have a second monitor plugged into VGA in my motherboard. This monitor is not detected. I have run lscpi -v

Hello,

I unistalled the nvidia drivers and the second monitor works again. I will post the output of xrandr and lscpi -v for this case.

Maybe this helps.

Edit: You have hybrid graphics. Did you set up optimus-manager?

Hello,

I thought that this was for laptops only. I have a desktop with dedicated nvidia and integrated intel. Does that apply to my case? Mine is not a laptop.

Thanks,

Sorry, I misread your hardware not paying attention. You are right.

Edit: Have you tried it using an xorg.conf

I can’t imagine that making a difference, but I’d love to be corrected if I’m wrong.
