Hello there,
I have an issue and I think I'm too junior to fix it by myself.
I have a PC from System76. It's an Adder WS running Debian 12 XFCE on the kernel version 6.1.0-27-amd64.
I am trying to connect this PC to an external monitor, via HDMI. Unfortunately the monitor doesn't detect the PC. It only displays "Input signal not found" before going into sleep mode. I assumed it was due to missing nvidia drivers.
I runned the following commands:
My conclusion was that the nouveau drivers don't support my Nvidia GeForce RTX 4070 Max-Q / Mobile. I followed the official documentation to install the proprietary drivers. First I ran nvidia-detect, installed nvidia-driver as recommended in the output and rebooted my PC.
Now the situation is even worse. lspci | grep -i vga doesn't even detect the Nvidia GPU anymore (only Intel Graphics show up) and lsmod | grep -E 'nvidia|nouveau gives an empty output.
To be honest, I hate non-free software. It's so frustrating. All I want is to be able to connect the PC to an external monitor which is a basic thing...
Could you please help me to fix it?
I read stuff online about Hybrid, optimus and a bunch of other stuff but at this point I'm so frustrated that I'm barely able to write this post without punching the PC.
Thank you for your help.
PS:
- The monitor is not faulty, it works with my other PC
- I tried using an USB-C to HDMI adapter to make sure the HDMI port wasn't damaged
- I tried different HDMI cables
EDIT: Even after purging all the nvidia-* packages I still can't detect my GPU anymore and the nouveau kernel module isn't loaded. I read it could have been blacklisted but I find no traces of that.
